Android Bitcoin Wallets

Finding the best bitcoin wallet for Android is hard. There are so many options!

Luckily for you, today I’ve organized the most popular wallets for Android to make deciding which one to use easier for you.

Large amounts of bitcoins should not be stored on your Android device! If you want the most secure Bitcoin wallet then you will need to use a hardware wallet like the Ledger Nano S or TREZOR.

You should always do research before downloading or installing any Bitcoin wallet. Many wallets are malware and will just steal your bitcoins once you fund the wallet.

Samourai Wallet

Samourai Wallet is a privacy focused Android Bitcoin wallet. It is very simple to use, yet packs in powerful privacy features for more advanced users.

This makes it a great choice for new users and users with extra needs.

breadwallet

Out of all the wallets we’ve tested, breadwallet is by far must user-friendly.

It’s so simple I could almost–almost!–see my grandma using it!

It offers basic send and receive features so it’s not confusing for first-time users.

There’s no weird Bitcoin terminology although you will need a basic understanding of Bitcoin.

If you are just getting started with Bitcoin it makes a great option!

The Mycelium Wallet is a featured-packed wallet that advanced Bitcoin users will love using.

It has support for many of the hardware Bitcoin wallets and even offers support for connecting through Tor if you want extra privacy.

Airbitz is a great wallet if you are making frequent Bitcoin payments.

The wallet has a number of plugins that make spending bitcoins easier:

  • Fold Integration: This integration allows you to buy Starbucks and Tartet gift cards from within the app.
  • Bitrefill Integration: You can easily top up your mobile phone from within the wallet!

If after reading this you’re converting to iPhone, then check out the best bitcoin wallets for iPhone !

Frequently Asked Questions

Any risks if I am using a rooted Android device?

Rooted Android devices are more vulnerable to being hacked. Chances are you won’t have any issues running a Bitcoin wallet on a rooted Android, but we still advise against this especially if you are dealing with large amounts of bitcoins.

Why can’t I store large amounts of bitcoins on my Android device?

Android devices are usually connected to the internet via Wi-Fi or cellular connection. Since internet connected devices are easier to hack, it’s best not to use an Android device for significant amounts of coins. Wallets connected to the internet are called ‘hot wallets’.

If you want secure storage, you’ll need to use an offline wallet—also called cold storage—like a hardware wallet or paper wallet.

Do hardware wallets work with Android devices?

Yes—unlike iOS—Android devices work with hardware wallets. This means you can plug in your hardware wallet to your Android phone with an OTG cable to securely sign transactions with your hardware wallet and broadcast it with your Android device.

Mycelium, Copay, and Greenbits are three wallets that currently work with hardware wallets on Android.

Are Android wallets free or paid apps?

All of the Android wallets listed on this page are 100% free apps. Hardware wallets are the only Bitcoin wallets that cost money—for now.

If someone has access to my phone, can they take my bitcoins?

It depends on what wallet you’re using. Some wallets allow you to set a PIN code so that only you can access the coins. Most of the wallets listed above also encrypt your wallet so that it would be very hard for the average person to access should they have your phone.

Still, you should always keep backups and if you do lose your phone, restore the wallet backup onto your new phone or send them to a different wallet.

How do I create a backup of my wallet?

Each wallet will walk you through backing up your wallet when you set it up. There are different methods. Most have you write down a 24 word seed that is a backup of your wallet.

Can I use more than one wallet at a time?

Of course. There are no limitations on how many or which wallets you can use. We recommend you download a few wallets, test them out and decide which one you like best!

Are there any wallets that work both on my Android and desktop computer?

Yes, but there are not a ton of options. Copay is one of the few wallets that works cross-platform, meaning you could use it on your Android phone and desktop at the same time. All of your transactions would be the same across all of the devices.

What’s better about using an Android wallet over a web wallet?

Web wallets like blockchain.info have a long history of bugs. Web wallets are also accessed in your browser, so it is much easier to fall for simple phishing attempts and lose your coins.

I personally receive a few phishing emails a week in my inbox targeting blockchain.info users. These end up in my spam folder, but it’s still a risk that less technical people may accidentally mess up with, which is why apps installed on your device can provide a bit more security.

I only need secure storage, so do I have any use for an Android wallet?

If you use a hardware or paper wallet for secure storage of bitcoins, nice job! Having an Android wallet installed on your device still might be helpful.

Once you buy bitcoins, it’s always best to get them off the exchange and into your own wallet. So if you can’t access your hardware wallet, you can at least send coins from the exchange to your Android wallet before you get on your desktop computer and send the bitcoins to your paper or hardware wallet.

You can always keep a little bit on your wallet to show your friends how Bitcoin works by sending them a small amount!

Any risks to be aware of?

Yes! While this specific issue has been more of a problem with iOS, know that Google Play Store does not check every wallet that it allows into the store.

There have been many apps that were approved by Google that were simply malware and stole any bitcoins that were deposited.

Do research on any wallet you download especially if you’re going to use it with significant amounts of money. We do not like to see people have bad experiences with bitcoins, especially since the transactions are irreversible.

Also, make sure you are download the correct wallet from the right developer. Not only have there been scam wallets that stole bitcoins, but many of these had the same logo and looked exactly like legitimate wallets. You should go to the website of the provider follow the download link from there.

Is Coinbase Android wallet a good choice?

Here is one of the biggest misconceptions about Coinbase:

It is not a Bitcoin wallet!

Coinbase has even said this themselves!

Coinbase is a fine place to buy your first bitcoins, but not a good place to store them. Once you buy bitcoins, move them into a wallet you control!

There is a long history of hacks where users lost bitcoins. Coinbase stores over $1 billion worth of digital currency and is a huge target for hackers. If Coinbase gets hacked, they will likely spread the losses evenly across all customers. This is what other exchanges have done in the past, like Bitfinex and Mt. Gox.

What about the blockchain.info Android app?

Even though blockchain.info has an app, it’s still a web wallet. If you’re using it for very small amounts it’s probably fine, but we really recommend against using web/online wallets unless you have a very specific need.

Greenbits Review and User Guide

GreenBits is the native Android version of GreenAddress. We hope this Greenbits Review will help you decide if it’s the right wallet for you!

It’s a multi-signature wallet that supports hardware wallets like TREZOR and Ledger. Seeds created with GreenAddress can be imported into GreenBits.

By default, GreenBits is a 2 of 2 multisignature wallet. In this case, you control one private key and GreenAddress the other. GreenAddress must sign every transaction.

GreenAddress claims that it will never sign a double-spend transaction. Users can send & receive to other GreenAddress and GreenBits users and receive instant confirmations, but this only works if the other party trusts GreenAddress.

Some features, like disabling 2FA and spending limits, must be set using GreenAddress and not GreenBits.

Greenbits Security

A mobile wallet is only as secure as the device it’s running on. GreenBits encrypts all your data and keys. An unrooted Android device should be used.

A backup is made by writing down the 24 word seed provided in the app. If the phone is reset or lost, all funds can be recovered by re-entering the seed.

GreenBits offers a unique setup with its options of 2-2 wallets and 2-3 wallets.

In a 2 of 2 wallet, you control one key and GreenBits controls the other. If GreenBit’s servers go down funds cannot be spent immediately because it would be impossible to access GB’s signature. GreenBits solves this by providing nLocktime transactions, which release funds after a chosen period of time. You must set this up using GreenAddress.

GreenBits relies on GreenAddress’s servers for transaction data, and also uses Electrum servers for extra verification.

A user-set PIN is required to open your wallet each time.

Greenbits Privacy

GreenAddress plans to add CoinJoin to GBits in a future update. GreenBits/GreenAddress know your IP address, balance, and addresses.

As an HD wallet, GBits generates a new address for every transaction and does not re-use addresses. Using a new address for each transaction helps prevent spying on your payments and funds.

“Schildbach Wallet” Review and User Guide

Bitcoin Wallet, or “Schildbach Wallet”, was the first mobile Bitcoin wallet and has over 700,000 users in the Google Play Store and about 100,000 users in the BlackBerry AppWorld.

Schildbach Wallet Security

A mobile wallet is only as secure as the device it’s running on. An unrooted Android device should be used.

A file containing the wallet’s private keys are encrypted and stored on your phone. The file should be backed up to another location in case your phone is lost or reset.

Bitcoin Wallet is more secure than most mobile Bitcoin wallets, because it connects directly to the Bitcoin network with SPV. Most other wallets connect to centralized servers for transaction information.

Schildbach Wallet Privacy

Bitcoin Wallet is an HD wallet. It generates a new address for each transaction making it more difficult for spying or tracking your payments.

Because the wallet connects directly to the Bitcoin network peers can see your phone’s IP address.

Bitcoin Wallet received a score of 46 out of 100 from the Open Bitcoin Privacy Project’s Spring 2015 report.

Mycelium Android Review and User Guide

Mycelium, founded in 2008, is a Bitcoin company with 35 employees located in Europe, Asia, and America. Mycelium offers mobile wallets for iPhone and Android. All of Mycelium’s applications are open source.

Mycelium is a good option for new users, with basic features like watch-only addresses, cold storage spending, and HD accounts. Advanced options include TREZOR support, xpub/xpriv key exports, and decrypting BIP38 keys. Mycelium can also be used to restore a TREZOR seed.

Mycelium Security

A mobile wallet is only as secure as the device it’s running on. Mycelium encrypts all your data and keys. An unrooted (Android)/non-jailbroken (iOS) device should be used.

Users can create a backup by writing down the 12 word seed provided in the app. If the phone is reset or lost, all funds can be recovered by re-entering the seed.

Mycelium is a hot wallet and should not be used to store a significant amount of funds.

Mycelium Privacy

Both the iOS and Android apps connect directly to the Mycelium’s servers. Directly connecting to Mycelium’s servers allows for instant connection to the Bitcoin network, but reduces privacy.

Mycelium’s servers can view your IP address and wallet balance. The company website claims to not log IP information, but there is no way to be sure. Orbot/Tor can be used to hide your IP address from Mycelium.

As an HD wallet, a new address is created for every transaction and addresses are not re-used. Using a new address for each transaction helps prevent spying on your payments and funds.

The Mycelium developers recognized that users value their privacy, and plan to implement CoinJoin in future updates.

Mycelium received a score of 50 out of 100 from the Open Bitcoin Privacy Project’s Spring 2015 report.

breadwallet Review & User Guide

breadwallet had long been one of the most popular Bitcoin wallets on iOS. Luckily for Android users, it finally launched on Android in July 2016.

We hope this breadwallet review and user guide will help make using the wallet and Bitcoin easier.

First, this is our favorite part about breadwallet:

The wallet is super simple to use!

breadwallet definitely understands that Bitcoin is confusing. The company has kept the wallet bare bones and it’s pretty clear how to use the wallet even if you know nothing about Bitcoin.

The interface is simple and it’s easy to send and receive Bitcoin payments.

And that’s enough for most users!

The only thing lacking in breadwallet are advanced features. But the company’s target market appears to be new Bitcoin users so the lack of advanced features is not an issue.

How to Use breadwallet

First, download breadwallet from the Google Play Store.

Once installed, open the app and you should see a screen like this:

Select “new wallet” since you want to create a new wallet. (We’ll get into “recover wallet” later in this post).

Now breadwallet will ask you to generate a wallet recovery phase. This phrase is your wallet backup. Click “generate recovery phrase”.

You may be required to enter your Android phone’s password once clicking “generate recovery phrase”.

breadwallet will now display warnings that you should definitely follow!

Remember, the 12 word “recovery phrase” you’re about to get is the backup of your wallet. Anyone else who has these 12 words can access your wallet even without access to you Android phone. So be careful!

Follow what breadwallet says and do not share the code with anyone, let anyone else even see it, and do not enter it into a password manager or software!

In the next step you will finally receive your 12-word recovery phrase. I would show a picture, but the wallet does not allow you to take a screenshot of the phrase.

Make sure you write down your phrase because you will need to confirm the phrase to prove you wrote it down.

Once you confirm your phrase, that’s it!

You should now see a screen like this:

The above picture is your receiving address. Anyone with that address can send you bitcoins!

Note: the address will change each time you receive a payment.

So to receive bitcoins, you would just have someone scan the QR code above or you could email/text someone the address above (1QFV…7v8).

Now I am sure you want to know: how can you send bitcoins with breadwallet?

Just scroll to the left and you should see a screen like this:

Once you are there tap “scan QR code” if you want to pay to a QR code. Once you scan a QR code of a Bitcoin address you can enter the amount you want to send:

We realize your wallet is probably empty right now. Don’t worry:

In the next step we will give you a few tips on how you can add money to your wallet.

You can also go back to the main sending screen and tap “pay address from clipboard”. This can be useful if you received a Bitcoin address via SMS or email and want to send to it.

How to Add Funds to breadwallet

As of now, breadwallet does not offer a way to buy bitcoins from directly within the wallet.

You’ll need to purchase bitcoins from an exchange and then send them to your wallet. Here are some exchanges you can use:

  • Coinbase : Coinbase is easy to use and a good option to buy for residents of the US, Canada, Europe, UK, and Singapore.
  • Bitstamp: Bitstamp is a regulated and licensed exchange based in Europe. Customers from around the world can make deposits.
  • Worldwide: You can use our site, Buy Bitcoin Worldwide, to find exchanges to buy bitcoin in your country.

breadwallet Fees

You may notice when sending a payment there is a small fee attached.

This is not a fee charged by breadwallet, but a fee you pay to the Bitcoin network.

This fee will vary based on when you send your transaction and how much money you’re sending.

breadwallet FAQ

This section aims to answer some of the most common questions about the wallet.

Can I Buy Bitcoins from Within breadwallet?

Not yet. breadwallet is working on this feature but it has not enabled it for all of its users.

breadwallet Import Private Key

If you want to important bitcoins from another wallet it’s easy to do. Just go to the settings and select “import private key”.

From there you can scan any private key QR code and send bitcoins using the app.

breadwallet Recovery Phrase

Although we already discussed the recovery phrase earlier, it deserves its own section.

As noted on setup, make sure you keep your recovery phrase in a safe, secret place.

This is especially true if you are storing large amounts of bitcoins in breadwallet–although ideally you should use a hardware wallet like the Ledger Nano S for storing larger amounts.

Send from breadwallet to Bank Account

There is no way to “send” bitcoins from your breadwallet to a bank account.

You will have to send the bitcoins from your wallet to a Bitcoin exchange where you can then sell them and transfer the money to your bank account.

We recommend a few places for selling your bitcoins from the wallet:

  • Coinbase: a good option to sell for residents of the USA, Canada, Europe, UK, and Singapore.
  • Kraken: a good option for European and Japanese residents.

breadwallet vs. Coinbase

It is hard to directly compare breadwallet and Coinbase.

Coinbase is more of an exchange than a wallet and should NOT be used to store bitcoins. When you use Coinbase, Coinbase controls your private keys. Storing your bitcoins with breadwallet means you control your private keys.

breadwallet vs. Blockchain Wallet

Blockchain is a web-wallet although it does offer apps for iPhone and Android.

As for simplicity, we thing breadwallet makes the better choice if all you need to do is send and receive bitcoins.

breadwallet vs. Mycelium

Mycelium is probably the most popular Bitcoin wallet for Android.

Mycelium is also pretty simple to use although it offers more advanced features. The advanced features in Mycelium may confuse people so if simplicity is your goal, breadwallet has the slight edge.

How to Transfer Bitcoins from Coinbase to breadwallet

Coinbase is the most popular exchange in the USA, and breadwallet is a popular Android wallet. So it’s no surprise we get asked how to send bitcoins from Coinbase to breadwallet.

It’s actually quite a simple process. Simply open breadwallet on your Android device and find the page that shows your Bitcoin address. It should look something like this:

Now login to your Coinbase account and go to “Send/Request” on the left side:

From there just enter the Bitcoin address from breadwallet and enter the amount of bitcoins you want to send:

Click “Send” and that’s it! The bitcoins from Coinbase should be on the way to your breadwallet.

breadwallet Support

breadwallet has a detailed FAQ on their website that should help answer most basic questions.

If you need further support then you can email them.

Airbitz Review & User Guide

Airbitz is easily one of the most popular Bitcoin wallets for Android. The company released its Android app in 2015, so the wallet has been around for a while now.

We hope this Aribitz review and user guide will help make using the wallet and Bitcoin easier!

How to Use Airbitz

First, download the app from the Google Play Store.

When you open the app you will have to agree to the terms of use.

Once you agree you’ll be presented with this screen:

Since we want to create a new wallet, tap “Sign Up”.

Enter a username for your Airbitz account:

Enter a PIN code for your account:

Enter a password for your account:

Airbitz will let you verify your info. You may want to write it down because if you lose the information, you also lose access to any bitcoins stored in the wallet.

You should now be brought to a screen that looks like this:

From this screen you can access most of the wallets features.

Receive Payments & Get Your Bitcoin Address

To get your Bitcoin address and receive payments tap on “Request” and then you should see a screen like this:

You can have a friend or anyone else scan the QR code shown on this page to accept payments.

Note: The address on this page will change with each payment!

  • Press “Copy” at the bottom copy the Bitcoin address to your Android phone clipboard
  • Press “email” to email the address
  • Press “SMS” to text the address

These features make it easy for you to share your Bitcoin address with anyone and to receive payments.

Send Bitcoin Payments

From the “Receive” tab where your QR code is displayed, tap the menu icon in the top left.

Now you can see a full list of menu items. Tap “Scan QR Code” to send bitcoins. You should now see a screen like this:

Your camera will now open up for you to scan. If you instead want to send to an address that you coped to your clipboard, just hid “Address” at the bottom.

With that you should be well on your way to sending and receiving Bitcoin payments with the Airbitz wallet!

How to Add Funds to Airbitz

Airbitz offers a way to buy bitcoins from directly within the wallet.

If you don’t want to use the built-in wallet funding method, here are some more ways to buy bitcoins to fund your wallet.

You’ll need to purchase bitcoins from an exchange and then send them to your wallet. Here are some exchanges you can use:

  • Coinbase : Coinbase is easy to use and a good option to buy for residents of the US, Canada, Europe, UK, and Singapore.
  • Bitstamp: Bitstamp is a regulated and licensed exchange based in Europe. Customers from around the world can make deposits.
  • Worldwide: You can use our site, Buy Bitcoin Worldwide, to find exchanges to buy bitcoin in your country.

Airbitz FAQ

Is Glidera Safe to Link Your Bank Account?

It is safe to link your bank account to Glidera in the sense that the company is not a scam.

Like with any information online, you still have to trust that they will keep your banking information and personal details secure.

Why does it say Airbitz Pending Transaction?

Sometimes the Bitcoin network is being used by too many people at once! This may result in your transaction being stuck for a bit. If so, don’t panic.

You may just have to wait a bit longer until your transaction confirms.

Airbitz Fees

You may notice that when you send a transaction with Airbitz you are charged a small transaction fee.

This is not a free charged by Airbitz the company, but rather a fee you pay to have your transaction processed by the Bitcoin network.

The fee will vary depending on when you send the transaction and how much money you are sending. Read more on the FAQ page.

Airbitz vs Copay Wallet

Airbitz is a unique wallet in that it has many extra features. If you are interested in these features Airbitz is probably better, but Copay is also a great wallet!

Airbitz vs Coinbase

It is tough to compare Airbitz and Coinbase.

Coinbase is an exchange and NOT a wallet. So if you want to buy bitcoins, it may be easier to buy bitcoins in Coinbase rather than using Glidera.

For storing bitcoins Airbitz is by far the better option.

Airbitz vs breadwallet

Airbitz and breadwallet are both popular wallets for Android. But really, they are not competing with each other.

breadwallet aims to just offer basic send and receive features to make using their wallet as easy as possible.

Airbitz is also easy to use but offers many features that may feel overwhelming for new users.

If you are serious about getting into Bitcoin then Airbitz may be more the “power wallet” you are looking for.

If you just want to send and receive payments then breadwallet will do that just fine!

Airbitz vs Mycelium

Mycelium is different than breadwallet in that it offers more advanced features.

Users in search for those extra features may have a tough time deciding between the two!

If you care about privacy, Mycelium offers Tor support so it has an edge over Airbitz in that category.

Airbitz Customer Service

The company’s website has contact information in the footer of its website that you can use for support or to report bugs with the wallet.

5 Best Bitcoin Wallet Apps for Android

This post was last updated in October 2014.

Hi guys, we’re adding two more Bitcoin wallet apps for Android to this list, we hope you find our selection useful.

If you are new to the crypto currency scene, you have probably missed the chance to make crazy money. Bitcoin, as most people have heard by now, is one of the most popular crypto coins, along with Litecoin etc. Unfortunately, the currency is still very volatile and rates keep fluctuating several times during a day. If you own an Android device and want to manage your Bitcoins or simply check the existing exchange rates, here are the best apps you can use.

Bitcoin Wallet by Blockchain

Note: Blockchain recently underwent a major upgrade and the interface is now much more user-friendly. Definitely our first choice for an Android bitcoin wallet.

I personally use Blockchain because it is one of the most secure Bitcoin wallets on the internet. Given how easy it is for a wallet service to make off with your precious coin, reliability is key here. The Blockchain app is easy to use and provides a pin-code security function for added protection. You can easily view your balance, its current value in the currency of your choice and the ongoing exchange rate to a variety of other currencies.

While I have had a good experience with this app so far – when it comes to money, due diligence is your own responsibility.

Best Bitcoin wallets for Android in 2018

Keep your cryptocurrency portable with these Android wallets

Bitcoin (BTC) was originally invented as a decentralized and easy-to-use payment system. To this end there are a huge amount of wallet applications available for Android phones and devices, allowing you to take your BTC with you on the move.

In this guide, you'll discover five of the most popular Bitcoin wallets for Android available today. While we've tried to select apps that are as simple to use as possible, if you do have a large amount of BTC you may want to choose a wallet with more security features such as GreenBits. If you only have a small amount of Bitcoin and just want to test the water, you can get started immediately with apps like Bitcoin Wallet.

Bitcoin isn't the only cryptocurrency on the market today. If you hold any other kind of virtual currency, or would like to exchange some of your coins, you may prefer a multi-currency wallet such as Coinomi.

When picking a wallet that's right for you, whatever choice you make, we strongly suggest you stick to the ones available either in the Google Play store or the F-Droid repository, as these are less likely to contain malware.

1. Electrum Bitcoin Wallet

The ultimate lightweight and portable Bitcoin wallet

Electrum is well-known in the Bitcoin world as one of the most popular 'thin clients' for storing Bitcoins, and the Android app doesn't disappoint. After downloading, your wallet is generated using a 'seed' of 12 random words, which you must write down. If anything happens to your Android device, you can then use this seed to restore your wallet along with your BTC. Your 'private key' is not locked in to Electrum and you can export your BTC to another wallet if you wish.

The Electrum Bitcoin Wallet for Android takes security seriously: your seed and private keys never leave your device. During setup you're also asked to create a 6-digit PIN which is used to confirm payments. If you already use the desktop version of Electrum, you can even set up a 'watching only' wallet on your phone which lets you view your balance and receive BTC – but not send them.

The most recent version of Electrum Bitcoin Wallet comes bundled with its own QR scanner to easily capture wallet addresses and send payments. To receive BTC, just tap on the 'Receive' section to display a handy QR code for others to scan. This feature is only compatible with the ZXing QR Scanner. If you use another app to scan codes, be warned that this may cause compatibility issues.

2. Coinomi Wallet

Manage and exchange all your coins in one place

Coinomi Wallet was originally created in 2015 and has since developed a solid reputation as a great wallet for storing not only Bitcoin but other cryptocurrencies, including Litecoin, Dash, Bitcoin Cash, Ethereum, not to mention any amount of Ether tokens. During setup you can choose which coins to display in the handy 'overview' section which lists the current market price and value of each currency.

Like Electrum, your wallet addresses are generated using a 'master seed' of 12 random words which never leaves your device. You can use this to restore your wallet balance for all of your coins should anything happen to your device. Coinomi offers the option to set a password during setup rather than a mandatory PIN as with Electrum. If you choose not to set a password, make sure your Android device has screen lock enabled and is encrypted.

Coinomi has integrated support for exchanging different coins using either of the services Shapeshift or Changelly for a small fee. User reviews have reported occasional issues with this whereby transactions don't confirm for some time, although this wasn't an issue during our own tests.

As of January 2018, Coinomi also no longer appears to be open source. This means that it's very difficult to know if there are any undisclosed security bugs or backdoors in the software.

3. MyCelium Bitcoin Wallet

Benefit from a Swiss army knife of privacy features

Mycelium is one of the most highly acclaimed Bitcoin wallets around. The website claims that Mycelium won the ‘Best Mobile App’ award from Blockchain.info in 2014, and that there's no wallet which has more stars from reviews on Google Play.

Mycelium is entirely open source, which means it's much easier to check for any software bugs, and also near-impossible for developers to include hidden backdoors to steal your BTC.

The interface is laid out in very simple fashion with buttons to send and receive BTC as well as scan in QR codes. Mycelium also has a built-in address book for making payments.

The settings section of Mycelium contains a massive arsenal of security features. First and foremost is the security PIN which you can set so that Mycelium requests it each time you make payments. The app also supports sweeping private keys from paper wallets, as well as 'cold storage' wallets which will only display your balance, and cannot be used to send BTC.

Although there's no desktop equivalent of Mycelium, you can use it with hardware wallets like Trezor to digitally 'sign' transactions. This makes it much harder for anyone to steal your Bitcoins.

At the time of writing Mycelium doesn't support Segwit. You can read more info about what this is and why it matters here. However, this should not affect everyday transactions.

4. GreenBits Bitcoin Wallet

Spend your Bitcoin quickly and securely

GreenBits is a secure and open source Bitcoin wallet. It is truly cross-platform in that as well as being available for Android, there's also a GreenAddress Chrome extension allowing you to manage your BTC from any device running Google’s browser.

If a person or company supports the GreenBits wallet service, BTC can be sent without needing to wait for confirmation via the Blockchain (which can take hours or days), allowing for near-instant payments. Each payment also has a unique 'hash' preventing fraudsters from spending the same coins twice.

During setup, a 24-word mnemonic is created which you can use to restore your BTC on another machine if anything happens to your Android device. The app also prompts you to set up payment confirmation via two-factor authentication.

GreenBits is secured via a PIN which you create during setup. If you fail to enter the PIN correctly three times, your wallet's decryption key will be destroyed. After that, the only way to recover your BTC is by re-entering the 24-word mnemonic.

This makes for a very secure wallet, although the setup process might be a little intimidating for newer users who only hold a small amount of Bitcoin. The good news is that once you have secured your wallet, the interface is very easy to navigate. BTC can be sent by entering an address or scanning a QR code.

5. Bitcoin Wallet

One of the simplest ways to get started with Bitcoin

With BTC transaction fees skyrocketing at present, users may also be concerned that there's no built-in feature to manage these either. Bitcoin Wallet simply informs you what the transaction fee will be.

The developer of the free and open source Bitcoin Wallet claims that its Android app is the oldest in existence, and that it's one of the easiest ways to get started with Bitcoin.

Unlike other wallets which require you to set up a PIN or write down a seed, you can use Bitcoin Wallet immediately after installation. The interface couldn't be any clearer – simply click 'Send' or 'Receive' to manage your BTC. There's even a handy address book to keep track of your favorite payment destinations. Your current balance is displayed in mBtc (millibitcoin) by default, as well as your local fiat currency, but you can change this in the app’s settings.

This extra simplicity comes at the price of security, however: anyone with access to your device could open the app and steal your Bitcoins. Your private keys, which are used to send payments, are stored securely on your Android device, but there doesn't seem to be an easy way to recover your BTC if anything happens to the device itself.

The app does, however, support 'sweeping' of paper wallets – in other words, scanning the private key of a Bitcoin paper wallet to empty it and add the BTC balance to the wallet app.

2018’s Best Bitcoin Wallets for your Android Mobile Device Reviewed

Last updated on March 4th, 2018 at 02:30 pm

If you’re looking to store your first Bitcoins and you own an Android mobile device this post is for you. However, before I review the best Android Bitcoin wallets out there I just want to give you a word of warning.

Mobile wallets (Android, or iOS) are the least secure form of Bitcoin wallets. This is mainly due to the fact that mobile devices tend to get stolen, lost and break down. If you hold your Bitcoins in a mobile wallet, it means that the private key is stored on the device, and therefor if the device is ruined or stolen you can’t access your coins.

Having said that, you can always create a backup for your wallet by using the 12-24 word seed phrase shown to you when you first install the wallet. That’s why it’s important to keep this seed phrase in a safe place and out of anyone else’s reach but your own.

If you’re completely new to Bitcoin watch this video regarding Bitcoin wallets, it will probably answer a lot of questions you already have:

And now for the wallet reviews…

#1 – Coinbase – Coinbase IS NOT a Bitcoin wallet

Usually when people think about Bitcoin wallets they think about Coinbase. However Coinbase isn’t a Bitcoin wallet. It’s actually an exchange that lets you hold Bitcoins. In a blog post written by Coinbase’s CEO Brian Armstrong, he states

you’ll see the Coinbase brand shift from being a hybrid wallet/exchange to focusing on purely being a retail and institutional exchange

So while Coinbase is still a cheap place to get Bitcoins, please don’t consider it as a mobile wallet. Coinbase does not give you access to your own private keys nor privacy, as we’ve covered in our review.

The real #1 – MyCelium Android Bitcoin wallet

MyCelium is a popular mobile app wallet that features a wealth of advanced privacy and security features. Yes, the wallet can be a bit complicated for newbie users but it’s still one of the safest and fastest on the market. As an open source software program, MyCelium is constantly being upgraded.

The wallet doesn’t have a web or desktop interface meaning coins can be accessed only through your mobile wallet. The good news is that you can use Mycelium together with a hardware wallet in order to get maximum security for your coins.

#2 – BreadWallet Android Bitcoin wallet

BreadWallet is probably one of the simplest Bitcoin Android wallets around. The source code of Breadwallet is open and there are only very basic “send” and “receive” options featured within the wallet.

This will be very easy for people to get accustomed to on the one hand, but on the other, leaves the wallet exposed without any advanced protection in place. BreadWallet has a mobile version only for Android and for iOS.

#3 – Copay Android Bitcoin wallet

Copay is an open source multisig wallet created by Bitpay. Multisig, stands for multisignature, and it means that the wallet requires a certain amount of people to approve a transaction before it is executed. Kind of like a shared wallet (you can read more about it here).

This is great for security, but makes it harder to send out Bitcoins in some cases. Depending on your needs this just might be what you need. Copay has an Android, iOS and desktop version available.

#4 – Jaxx Android Bitcoin Wallet

Jaxx is a relatively new and controversial wallet. On the one hand Jaxx seems to be a clear winner when it comes to mobile wallets. It has an intuitive interface, can pair across multiple devices (meaning you can use the same funds out of your phone or desktop) and it holds a wide variety of cryptocurrencies (e.g. Ethereum, Litecoin, etc.)

However the main issue with Jaxx is that it’s not open source . Recently there was also a safety concern raised by developers around the community regarding the wallet. This issue has yet to be addressed. Please don’t store a large amount of coins on Jaxx if you don’t have to.

#5 – Airbitz Android Bitcoin wallet

Airbitz is another open source Android Bitcoin wallet you may want to consider. The wallet resembles BreadWallet in its simplicity but also offers a variety of features mainly aimed to support Bitcoin adoption. For example, the wallet displays a wide variety of merchants accepting Bitcoin or place you can buy discounted gift cards with Bitcoin.

#6 – GreenAddress (AKA GreenBits) Android Bitcoin Wallet

If all else fails you should check out GreenAddress. The wallet offers good features, good security and a slightly weak user experience. We’ve reviewed GreenAddress in the past and concluded it to be a solid choice for people who are more experience with Bitcoin.

Please remember the following rules when using a mobile wallet:

  • Always set a pin code protection for your wallet if possible
  • Never store large amounts of Bitcoin on your mobile wallet
  • Write down the 12-24 word seed you get when you set up your wallet and keep in a safe place.

Also keep in mind that not every wallet allowed into GooglePlay is verified. This means some people can create malicious wallet like apps in an attempt to steal your coins once you send them to your mobile wallet. That’s why it’s important to download only known apps and make sure that they are the official app you’re actually looking for.

    The 3 best Bitcoin wallets for Android

    *Are you looking for the best Bitcoin Wallets for iOS? Click here.*

    Android was the first mobile platform with Bitcoin wallets and has offered standalone apps, that don’t rely on a central server to process transactions, since very early in Bitcoin’s life. In the beginning, these decentralized apps downloaded the full Blockchain, which would barely be possible today, as it currently stands at over 60GB.

    Instead, just like ExpressVPN’s favorite iOS wallets, the applications rely on Simplified Payment Verification (SPV), where the wallet can directly connect to the Bitcoin network, but only syncs the most relevant data and not the entire blockchain.

    Mycelium – Easy to Use

    The Mycelium Bitcoin Wallet, named after a kind of fungus believed to be the largest living organism in the world, is an easy-to-use wallet that comes with just the right set of useful side features.

    It is the successor of wallet BitcoinSpinner and was launched in 2013. Mycelium has become the standard for mobile wallets and uses HD (Hierarchical Deterministic) seeds, meaning that to back up your Bitcoin, you only need to remember a set of twelve English words. Be careful when backing up your words, though, as anyone with these words has access to all your money. ExpressVPN recommends you to write them on a piece of paper and store it in a safe place, or use your password manager to save them.

    HD wallets help you preserve your privacy too, as the app will use a separate address for each transaction. Mycelium will go one step further, though, and allows you to route all your data through the Tor Network with the app Orbot. With this process, nobody will know you are even using Bitcoin.

    Also great for your financial privacy is the ability to separate your accounts with Mycelium. If you, for example, hold some Bitcoins as income and want to separate them from your savings, you can easily do that in Mycelium, just by adding an extra wallet. This makes record-keeping much easier, but don’t forget that when using multiple wallets, you will need to back them up separately.

    Mycelium also makes it easy to sweep all sorts of backups and paper wallets that you might have. Private keys in the form of a QR code can be scanned straight into your device, or you can type your twelve words into the app. Mycelium will then transfer the coins to one of its own secure keys.

    If you are particularly paranoid or concerned with security, or if you cannot trust the phone you are carrying (maybe because you have to share it with others), Mycelium can be used in connection with hardware Bitcoin wallets like Trezor or Ledger.

    These hardware wallets are external hardware devices specially made for securely storing Bitcoins. They look a bit like USB sticks but have a small display through which you can verify transactions. To make a transaction, you connect your hardware wallet to your phone, open the Mycelium app and initiate the operation. You will then verify and confirm the transaction in your hardware wallet. This way your private keys never leave your dedicated device and are only transmitted via your phone. Pretty genius stuff.

    The greatest side feature of the Mycelium app is the marketplace. You can easily find people near your location who are willing to trade Bitcoin for cash. It’s a great way stock up on some coin or liquidate your holdings in exchange for inflationary government money if you wish.

    You can even choose to become a trader yourself if you have extra time.

    Mycelium Summary

    • Easy to use and backup
    • Great app to sweep Bitcoin from cold storage
    • Support for hardware wallets
    • Trader feature to buy Bitcoin nearby

    Copay – Allows Multiple Signatures

    Copay is not only among ExpressVPN’s favorite Android wallets, but it was also a no-brainer for the iOS list. It may be the best cross-platform Bitcoin wallet out there, as it is also available for Windows Phone, Mac, Linux and as a Google Chrome extension.

    Copay’s biggest strength is the multi-signature feature. This means you can quickly set up a single Bitcoin wallet with multiple people or devices as signatories.

    You can use this feature to increase your security by creating a wallet that holds the funds between several devices. For example, you can create a Bitcoin address that has three keys, one on your phone, one on your computer, and one as a backup on a piece of paper. Each transaction requires two signatures, from your phone and computer, for example. A hacker would have to simultaneously attack both devices, which is considered magnitudes harder than just attacking a single device, to access your money. The third wallet is kept as a backup, in case your phone or computer get lost or damaged.

    You can also make use of multiple Copay addresses in your organization. For example, each board member or treasurer can hold a bitcoin wallet and key. To make a successful payment, a minimum number of signatures can be required to process the funds. This system is relatively secure from hackers, and you don’t have to trust a single individual in your organization with all the money.

    On the downside, the Copay app has to rely on a central server to monitor and broadcast transactions. This server is not able to steal your coins, but if it were subject to a DDoS attack, or be otherwise unavailable, you would not be able to spend your Bitcoin — an annoying nuisance.

    Theoretically, the app gives you the option to use an alternative server, and even to run your own. In reality, this will only be viable for larger organizations as it requires significant effort.

    Copay Summary

    • High powered, easy-to-use multi-signature wallet
    • Lots of features
    • Push notifications for incoming funds
    • Depends on a centralized server for key-management — risky for outages

    Schildbach Bitcoin Wallet – App Only 2.9MB!

    The Schildbach Bitcoin Wallet is named after its developer Andreas Schildbach (now known in the Play Store as simply “Bitcoin Wallet”) and is the oldest mobile Bitcoin wallet. The Schildbach wallet used to download the entire Blockchain before this process became too much of a burden due to the amount of transactions.

    With new SPV technology, it is no longer necessary to download the entire history of all Bitcoin transactions. Today applications can connect directly to the network, find out a wallet’s balance, and push signed transactions, without compromising on censorship, or uptime.

    The application is listed by Google as having between a million and five million installs, showing the impressive reach of the wallet.

    The wallet comes with simple functionalities, but it nonetheless shows what is possible with a decentralized permissionless system like Bitcoin. You can, for example, push Bitcoin transactions through to another device, via Bluetooth or NFC, as long as the devices support it.

    Schildbach Summary

    • Easy to use, slim application
    • Well maintained by one of the most experienced developers in the Bitcoin ecosystem
    • Support for NFC and Bluetooth
    • Only 2.9 MB

    Mycelium Is ExpressVPNs Favorite Bitcoin Wallet

    Mycelium is easy to use, looks good, has just enough features to be what you need, and the marketplace feature is also great if you need to stack on some Bitcoin.

    Copay has made multi-signature wallets usable and even fun. If you want extra security or the ability to spread funds between multiple people in an organization, this app will be your number one choice.

    Just like with iOS, all of the Android wallets ExpressVPN surveyed give a different address each time you make a transaction. This is good for privacy but does not make your transactions anonymous. If you require a high level of privacy or anonymity, check out ExpressVPN’s Guide to Bitcoin Anonymity.

    Choose your Bitcoin wallet

    Find your wallet and start making payments with merchants and users.

    Take time to educate yourself

    Bitcoin is different from what you know and use every day. Before you start using Bitcoin for any serious transaction, be sure to read what you need to know and take appropriate steps to secure your wallet. Always remember that it is your responsibility to choose your wallet carefully and adopt good practices in order to protect your money.

    Bitcoin Wallet

    Bitcoin Wallet is easy to use and reliable, while also being secure and fast. Its vision is de-centralization and zero trust; no central service is needed for Bitcoin-related operations. The app is a good choice for non-technical people.

    Control over your money

    This wallet gives you full control over your bitcoins. This means no third party can freeze or lose your funds. You are however still responsible for securing and backing up your wallet.

    This wallet uses SPV and the Bitcoin network. This means very little trust in third parties is required when verifying payments. However, it is not as secure as a full node like Bitcoin Core.

    The developers of this wallet publish the source code for the client. This means any developer in the world can audit the code. However, you still need to trust developers of this wallet when installing or updating the final software because it was not built deterministically like Bitcoin Core.

    This wallet is loaded on mobiles where apps are usually isolated. This provides a good protection against malware, although mobiles are usually easier to steal or lose. Encrypting your mobile and backing up your wallet can reduce that risk.

    Prevents spying on your payments

    This wallet makes it harder to spy on your balance and payments by rotating addresses. You should still take care to use a new Bitcoin address each time you request payment.

    Discloses limited information to peers

    Peers on the network can log your IP address and associate your payments together when receiving or sending payment.

    Tor not supported

    This wallet does not let you use Tor to prevent attackers or Internet service providers from associating your payments with your IP address.

    Full control over fees

    This wallet gives you full control over fees. This means that this wallet allows changing the fees after funds are sent using RBF or CPFP. This wallet also provides fee suggestions based on current network conditions so that your transactions are confirmed in a timely manner without paying more than you have to.

    Repair the Yahoo Search App.

    Yahoo Search App from the Google Play Store on my Samsung Galaxy S8+ phone stopped working on May 18, 2018.

    I went to the Yahoo Troubleshooting page but the article that said to do a certain 8 steps to fix the problem with Yahoo Services not working and how to fix the problem. Of course they didn't work.

    I contacted Samsung thru their Samsung Tutor app on my phone. I gave their Technican access to my phone to see if there was a problem with my phone that stopped the Yahoo Search App from working. He went to Yahoo and I signed in so he could try to fix the Yahoo Search App not working. He also used another phone, installed the app from the Google Play Store to see if the app would do any kind of search thru the app. The Yahoo Search App just wasn't working.

    I also had At&t try to help me because I have UVERSE for my internet service. My internet was working perfectly. Their Technical Support team member checked the Yahoo Search App and it wouldn't work for him either.

    We can go to www.yahoo.com and search for any topic or website. It's just the Yahoo Search App that won't allow anyone to do web searches at all.

    I let Google know that the Yahoo Search App installed from their Google Play Store had completely stopped working on May 18, 2018.

    I told them that Yahoo has made sure that their Yahoo members can't contact them about anything.

    I noticed that right after I accepted the agreement that said Oath had joined with Verizon I started having the problem with the Yahoo Search App.
    No matter what I search for or website thru the Yahoo Search App it says the following after I searched for
    www.att.com.

    WEBPAGE NOT AVAILABLE

    I tried to search for things like www.homedepot.com. The same thing happened. It would say WEBPAGE NOT AVAILABLE. The only thing that changed were all the upper and lower case letters, numbers and symbols.
    Then it would again say
    could not be loaded because:
    net::ERR_CLEARTEXT_NOT_PERMITTED

    This is the same thing that happened when Samsung and At&t tried to do any kind of searches thru the Yahoo Search App.

    Yahoo needs to fix the problem with their app.

    Yahoo Search App from the Google Play Store on my Samsung Galaxy S8+ phone stopped working on May 18, 2018.

    I went to the Yahoo Troubleshooting page but the article that said to do a certain 8 steps to fix the problem with Yahoo Services not working and how to fix the problem. Of course they didn't work.

    I contacted Samsung thru their Samsung Tutor app on my phone. I gave their Technican access to my phone to see if there was a problem with my phone that stopped the Yahoo Search App from working. He went to Yahoo and… more

    What is a Bitcoin Wallet?

    A Bitcoin wallet is the first step to using Bitcoin.

    A “wallet” is basically the Bitcoin equivalent of a bank account. It allows you to receive bitcoins, store them, and then send them to others.

    You can think of a wallet as your personal interface to the Bitcoin network, similar to how your online bank account is an interface to the regular monetary system.

    Bitcoin wallets contain private keys; secret codes that allow you to spend your bitcoins.

    In reality, it’s not bitcoins that need to be stored and secured, but the private keys that give you access to them.

    A Bitcoin wallet is simply an app, website, or device that manages Bitcoin private keys for you.

    This guide will show you how to create a bitcoin wallet and pick the best one.

    Types of Bitcoin Wallets

    Let's discuss the types of bitcoin wallets and why you might want to use one kind over another.

    Hardware Wallets

    A hardware wallet is a physical electronic device, built for the sole purpose of securing bitcoins.

    The core innovation is that the hardware wallet must be connected to your computer, phone, or tablet before bitcoins may be spent.

    The three most popular and best Bitcoin hardware wallets are:

    Hardware wallets are a good choice if you’re serious about security and convenient, reliable Bitcoin storage.

    Bitcoin hardware wallets keep private keys separate from vulnerable, internet-connected devices.

    Your all-important private keys are maintained in a secure offline environment on the hardware wallet, fully protected even should the device be plugged into a malware-infected computer.

    As bitcoins are digital, cyber-criminals could, potentially, target your computer’s “software wallet” and steal them by accessing your private key.

    Generating and storing private keys offline using a hardware wallet ensures that hackers have no way to reach your bitcoins.

    Hackers would have to steal the hardware wallet itself, but even then, it can be protected with a PIN code.

    Don’t worry about your hardware wallet getting stolen, lost or damaged either; so long as you create a secret backup code, you can always retrieve your bitcoins.

    Think of a hardware wallet like your own underground steel vault. If you own a significant amount of bitcoin, you should strongly consider getting one!

    Why are hardware wallets good?

    • Easiest way to securely store bitcoins
    • Easy to backup and secure
    • Less margin for error; setup is easy even for less technical users

    Why are hardware wallets bad?

    • They're not free!

    Hot Wallets

    Hot wallets are Bitcoin wallets that run on internet connected devices like a computer, mobile phone, or tablet.

    Private keys are secret codes. Because hot wallets generate your private keys on an internet connected device, these private keys can’t be considered 100% secure.

    Think of a hot wallet like your wallet today: you use it to store some cash, but not your life savings. Hot wallets are great if you make frequent payments, but not a good choice for the secure storage of bitcoins.

    Why are hot wallets good?

    • Easiest way to store small amounts of bitcoin
    • Convenient; spending and receiving payments is easy and fast
    • Some hot wallets allow access to funds across multiple devices

    Why are hot wallets bad?

    • Not safe for the secure storage of large amounts of bitcoins

    Which Wallet is Best for You?

    Investing or saving? Then a hardware wallet will keep your coins safe.

    Otherwise, a software wallet will send and receive bitcoins just fine. Best of all, software wallets are free.

    Each wallet has pros and cons, and different wallets are built to solve different problems.

    Here is a video that may help:

    Some wallets may be geared towards security, while some wallets may be more focused on privacy.

    Your specific needs should determine the wallet you use, as there is no “best bitcoin wallet”.

    Below, we've listed wallets you can buy or download. We suggest using the wallets listed or doing research before buying or downloading any wallet.

    Each day, new Bitcoin scam wallets are added to the Google Play Store and Apple app store that are designed to steal peoples' bitcoins.

    We only list wallets that have published and open-sourced their code.

    Hardware Wallets: Keep Your Coins Safe

    Hardware wallets aren't free.

    But the price can be worth it if you own a significant amount of bitcoins. A hardware wallet will protect a few hundred in Bitcoin just as effectively as a few million.

    How Hardware Wallets Work

    Hardware wallets are secure, offline devices. They store your private keys offline so they can't be hacked.

    This means you can even use one on a malware infected computer.

    Why A Hardware Wallet with a Screen is Important

    In the table below, you'll notice we show which hardware wallets have screens.

    Screens provide extra security by verifying and displaying important wallet details. Since the hardware wallet is nearly impossible to hack, its screen is more trustworthy than data displayed on your computer.

    Bitcoin Hardware Wallet Comparison

    Check the table below for a quick comparison. Note:

    Best Bitcoin Hardware Wallet Overviews

    Ledger Nano S Buy Learn More

    The Ledger Nano S is the cheapest of the three hardware wallets with a screen; it costs about $95. Ledger, one of the most well-known Bitcoin security companies, released the device in August 2016.

    TREZOR Buy Learn More

    TREZOR launched in August 2014 as the first Bitcoin hardware wallet, offering secure bitcoin storage plus the ability to spend with the convenience of a hot wallet. TREZOR is a small, thumb-sized device.

    KeepKey Buy Learn More

    KeepKey was released in September 2015 and was the second hardware Bitcoin wallet to offer a screen. The KeepKey's larger screen gives it some extra security features that the Nano S and Trezor lack.

    Hot Wallets

    Just a quick refresher:

    Hot wallets are Bitcoin wallets that run on internet connected devices like a computer, mobile phone, or tablet. As hot wallets generate private keys on an internet connected device, these private keys can’t be considered 100% secure.

    Think of a hot wallet like your wallet today: you use it to store some cash, but not your life savings. Hot wallets are great if you make frequent payments, but not a good choice for the secure storage of bitcoins.

    Online Bitcoin Wallets (Web Wallets)

    Web wallets store your private keys online, where they are encrypted with a user-selected password. Although they offer the lowest level of security, online bitcoin wallets have the advantage of being accessible from any internet connected device.

    GreenAddress

    GreenAddress is a multi-signature Bitcoin wallet available on the web, desktop, Android, and iOS. GreenAddress is compatible with hardware wallets like TREZOR, Ledger Nano, and the HW.1.

    “Multi-signature” in this context means that the site requires a manual confirmation from you for your coins to be moved; this greatly improves security.

    Android Bitcoin Wallets

    There is a large selection of Android wallets. Since Bitcoin wallets were originally banned by Apple, developers spent much of their time developing for Android.

    Samourai Wallet

    Samourai is 100% the best available Android wallet. It has the most features, the best privacy and its developers are constantly working to add the latest Bitcoin features to the wallet. Samourai Wallet has been around for more than 3 years and its code is fully open source.

    Mycelium

    Mycelium is the most popular Bitcoin wallet on Android. It's very easy to use for sending and receiving payments. Backing up your wallet is also simple, since Mycelium makes it very clear with setup and backup instructions.

    breadwallet

    breadwallet, the great iPhone Bitcoin wallet, recently released an Android wallet. It offers the user control of private keys, an easy to use interface, and passcode support.

    Edge

    Edge is an easy to use Bitcoin wallet for iPhone and Android. Its familiar login feature makes using the app a breeze for people new to bitcoin. The wallet also creates automatic backups, so you don't have to worry about the technicalities of performing manual wallet backups.

    GreenBits

    GreenBits is the native Android version of GreenAddress. It’s a multi-signature wallet that also supports hardware wallets like TREZOR and Ledger.

    Bitcoin Wallet

    Bitcoin Wallet, or “Schildbach Wallet”, was the first mobile Bitcoin wallet. Bitcoin Wallet is more secure than most mobile Bitcoin wallets, because it connects directly to the Bitcoin network. Bitcoin Wallet has a simple interface and just the right amount of features, making it a great wallet and a great educational tool for Bitcoin beginners.

    iOS and iPhone Bitcoin Wallets

    Apple banned Bitcoin wallets from the App Store in February 2014, but reversed its decision a few months later. Luckily, there are now plenty of options for iOS users.

    breadwallet

    We consider breadwallet, along with Copay (below), as the best bitcoin wallet for iPhone. It’s open source and gives the user full control over their private keys. It also has a clean interface which makes the sending and receiving of bitcoins a pleasurable and super-simple process.

    Edge

    Edge is an easy to use Bitcoin wallet for iPhone and Android. Its familiar login feature makes using the app a breeze for people new to bitcoin. The wallet also creates automatic backups, so you don't have to worry about the technicalities of performing manual wallet backups.

    Desktop Wallets

    Desktop wallets are downloaded and installed on your computer. If privacy is your main concern, the Bitcoin core wallet is a good option since it does not rely on third parties for data.

    Electrum

    Electrum is a light weight Bitcoin wallet for Mac, Linux, and Windows. Electrum was created in November 2011. The main features of Electrum are: support for hardware wallets (such as TREZOR, Ledger Nano and KeepKey), and secure Bitcoin storage using an offline computer. Electrum is a good option for both beginners and advanced users.

    Bitcoin Banks: $1 Billion Lost in Hacks

    One last thing to keep in mind when it comes to bitcoin wallets is that there is a difference between a wallet and a bank. Some Bitcoin users view Coinbase as a Bitcoin wallet, but companies like this operate much more like banks.

    The private keys are what users need to protect to safely use the Bitcoin network without getting robbed. When you hand someone else control over your private keys, you are essentially making a deposit at that financial institution – much like a deposit at any bank.

    Don't store coins on exchanges! Bitcoin users have lost over $1 billion worth of bitcoins in exchange hacks and scams. Control your own private keys.

    This is not to say that bitcoin banks are inherently bad. Companies like Coinbase have done wonders for bringing more users into the ecosystem. It is simply important to remember that whoever controls the private keys controls the bitcoin attached to those keys.

    A misunderstanding of this point has led to hundreds of millions of US dollars being lost in the past, so it’s important to understand this critical difference in how Bitcoin private keys can be stored.

    Understanding how bitcoin wallets work is an important aspect of safely using this new technology. Bitcoin is still in its early years of development and wallets will become much more user-friendly in time.

    In the near future, certain devices may eventually come with pre-installed wallets that interact with the blockchain without the user’s knowledge.

    For now, it’s vital to keep in mind that the private keys are what you need to protect if you want to keep your bitcoin safe from hackers, user error, and other possible issues.

    Theft and Scams

    No matter which wallet you choose, remember:

    Your bitcoins are only safe if the private key was generated securely, remains a secret, and--most importantly--is controlled only by YOU!

    Here are two examples where users got ripped off by leaving bitcoins in the care of a third party:

    To avoid theft, scams, and any other loss of funds, follow these three basic principles:

    1. Generate your private keys in a secure, offline environment. (Except if using trivial amounts, in which cases keys may be created in a hot wallet).
    2. Create backups of your private keys. This helps to protect against the loss of your bitcoins due to hard drive failure or some other problem or accident. Ideally you should have a duplicate set of backups kept off-site to protect against the possibility of fire, robbery, etc.
    3. Encrypt wallets to provide additional security. This helps prevent the physical theft of your funds in the event that your device or hardware wallet is stolen.

    Securing your bitcoins properly is the most important step for any Bitcoin user.

    With Bitcoin you have the privilege - but also the responsibility - to safeguard your own money. There have been countless scams related to Bitcoin that could have been prevented had people not entrusted others with their bitcoins.

    It’s a good rule of thumb to never trust anyone else with your money.

    Bitcoin Wallet Frequently Asked Questions

    Bitcoin wallets. What are they?

    Bitcoin Wallets let us send, receive and store Bitcoin amounts all the way down to the Satoshi unit.

    Wallets secure funds by guarding our private keys. These private keys act as the proof of ownership for our Bitcoins. As such, a Bitcoin wallet is like a key to your safe deposit box on the Blockchain.

    What is a private key?

    Private keys emerged as a way to communicate securely through insecure communication channels.

    Historically, before the advent of public key cryptography, the greatest cryptographic weakness was the inability to communicate the ‘key’ that makes sense of encrypted messages. As a solution, the use of two keys (public and private) entered the picture.

    It’s a nifty little trick.

    Keys come in pairs. The public key is used to encrypt the message whereas the private key decrypts the message. The only person with the private key is you. Everyone else is free to have your public key. As a result, everyone can send you encrypted messages without having to agree on a key beforehand. They simply use your public key and you untangle the gibberish by using your private key.

    Why should I care about private keys?

    At the end of the day, all of this can go over your head without much danger. Just remember that it’s good to know what you’re dealing with. Bitcoin wallets make use of a fundamental cryptographic principle that we use for things ranging from https for websites or sending anonymous tips to Wikileaks. Most importantly, by understanding private keys you’ll have a much easier familiarizing yourself with Cold Storage wallets.

    What is a Bitcoin address?

    A Bitcoin address is like an account number, just better. The address denotes which wallet the coins should be sent to. Like a bank account number, where the difference lies in the wallets having multiple addresses. These can be customized by including payment request information such as an amount and a date of expiration.

    What should I know about addresses?

    Bitcoin wallet addresses are case sensitive, usually have 34 characters of numbers and lowercase letters, start with either a 1 or a 3, and never use 0, O, l and I to make every character in the address as clear as possible. That’s a lot to take in. But don’t worry. What they consist of is largely irrelevant to you. Just know they’re a string of characters that denote a destination on the Bitcoin Blockchain.

    How do I generate a Bitcoin address for my wallet?

    How to generate a new Bitcoin Address varies between wallets. Some manage your addresses for you. Others give you full control. As with many other Bitcoin technologies, the option to dirty your own hands is always open.

    If you do end up taking the easier route, just press a button to generate a new address for your wallet.

    Some wallets, like Electrum, allow you choose in how many blocks your transaction should be confirmed. The faster you want your payment to go through, the more you will have to pay miners for confirming your activity. We find here another difference between Bitcoin wallets and Bank accounts. Given the right wallet, the control and oversight that we have over our transactions is far more extensive than that of the traditional banking system.

    How do I fund a Bitcoin Wallet?

    First, acquire some Bitcoins. Go through an exchange in your country, ask an acquaintance to share, or use Buybitcoinworldwide.com if you want as seamless of an experience as possible. The purchased coins can then be sent to your wallet by specifying one of its addresses.

    Some wallets, particularly online ones, also let you buy coins. Keep in mind that these come with larger exchange margins which are best left alone.

    Are Bitcoins safe?

    Is Bitcoin a safe way to store value digitally? Are we wise to save our coins on our computer? It’s true that online wallets are necessarily more dangerous than offline wallets. However, even offline wallets can be breached, meaning that security in the Bitcoin world depends largely on following good practices. Just like you would avoid flailing your bills about in a dangerous place, you should make sure to keep your passwords and keys as safe as possible.

    How do I secure my Wallet?

    • Secure your computer
    • Restrict unsupervised access. Set a strong password and close all ports and maintain a strict firewall.
    • Frequently change address. Use a different address for every transaction.
    • Multiple Signatures (Multi-sig). Multiple private keys to deter breaches.

    Where are Bitcoins stored?

    Bitcoins simply consist of a string of data. That’s why they can be stored anywhere. You could paint Bitcoin on a wall with your blood. Nobody does that though. Hopefully.

    Instead, we store BTC on computers because we need them handy to trade. After all, we need to be connected to the internet to send value from one wallet to another over the Blockchain.

    How do I open a Bitcoin account?

    To some readers this might seem like a weird question. Truth is, people coming from a financial or business background are likely to expect Bitcoin to be a direct alternative to our current financial system. This is not the case.

    You don’t need a Bitcoin account. There is no such thing really. You just need a wallet. The only accounts you might encounter are online wallets that are separated into various accounts via a user system.

    How do I know which wallet is best for me?

    Let’s be honest. It’s unreasonable to expect anyone else to make this decision for you. After all, your preference depends entirely on your personality and needs. So just be honest with yourself.

    Frankly, you shouldn’t need anything complicated if you’re using the wallet for simple internet expenses or as a way to save money.

    If, however, you’re planning to run a Bitcoin centered business make sure to use advanced wallets that support automated mass payments.

    Any common mistakes to be careful of?

    First of all, don’t rest your money in an exchange wallet. Keep your coins in an environment where you have complete control.

    Secondly, don’t keep all of your coins in one place. You’ll be crushed if you lose access to a wallet with all of your funds.

    Thirdly, double check the target address. Bitcoin transactions cannot be reversed, so don’t lose your coins forever to a stranger!

    Last of all, use trusted online wallets (if at all). Don’t just trust anyone with your money. Make sure that the online wallet provider has a reputation of upholding the highest possible security standards.

    Security Risks with Hardware Wallets

    Hardware wallets are more secure than any other software wallet, like one that runs on your Android or iOS device, or desktop. However, hardware wallets have some unique security risks to be aware of.

    Tampering of the Device

    We always recommend to order directly from the hardware seller. This is because someone can buy a hardware wallet, tamper with it, and sell it used. They could program it to steal any bitcoins or add a back door.

    Most hardware wallets add some special kind of tape on the packaging to try to make any tampering more noticeable. This is another reason we recommend only ordering from the hardware wallet company, and not from a website like eBay.

    Bad Random Number Generator

    Bitcoin private keys are based on cryptography. Random number generators, also called RNGs, are used to create the private keys that secure bitcoins.

    If the random number generator is not random enough, that means someone else can recreate the private key of the hardware wallet easier. This attack has happened in the past with blockchain.info, a web wallet. Over 300 BTC were lost because blockchain.info did not use good RNG, so a hacker was able to generate the private keys again and steal coins.

    One way to help prevent this is to use the hardware wallet’s custom 25th word. TREZOR, for example, allows you to add a 25th word to the 24 word seed. This means that you can technically add your own RNG to the computer generated RNG to ensure your private key will be truly based on good RNG.

    What happens if the hardware wallet company goes out of business?

    All hardware wallets listed above work with other wallets. So, if the hardware wallet company goes out of business you will still be able to use your wallet with a different wallet like Electrum.

    Let’s say you use TREZOR with TREZOR’s myTREZOR wallet. TREZOR goes out of business and no longer supports myTREZOR wallet and it gets shut down.

    You could, in just a few minutes, download Electrum on your computer. Once installed, you’d setup your TREZOR and all of your transaction history and balance would get imported and be exactly the same. This is because Electrum will use the same 24-word seed you generated with TREZOR on setup.

    Which wallets can be used for each device?

    Ledger Nano S, KeepKey and TREZOR all work with:

    • Mycelium (Android version only)
    • Electrum for Mac, Windows and Linux
    • Multibit HD
    • GreenAddress

    Do these hardware wallets work for Ethereum?

    Yes, all of these wallets work with Ethereum, Litecoin and many other coins.

    TREZOR and Ledger both have blog posts explaining their integrations with various Ethereum wallets.

    The hardware wallet tells me to write down the 24 word seed on paper.

    Should I take a picture of the seed with my phone as a backup?

    The seeds generated by hardware wallets are meant to be written down only. By taking a picture of your seed with an internet connected phone, you put your entire wallet on a device that is connected to the internet and easier for hackers to get into. Please do not do this!

    Why do the hardware wallets have buttons?

    The buttons are used to confirm transactions. In order to send a transaction, you must physically press or hold buttons on the devices. This is a security feature. If a hacker were to access the hardware wallet somehow, the hacker still would not be able to send a TX without physical access to the buttons. Read more about this in TREZOR’s security philosophy.

    Do hardware wallets work with Coinbase?

    One of the most frequent questions we get asked is how Coinbase works with hardware wallets.

    It’s a trick question!

    Coinbase does not work directly with hardware wallet. You should, however, send bitcoins from Coinbase directly to your hardware wallet once you buy. Never store bitcoins on Coinbase or any other exchange for long periods of time.

    Too many people in the past have lost money from hacks like Bitfinex and Mt. Gox.

    So, yes, use a hardware wallet in conjunction with Coinbase. Buy on Coinbase, then send to hardware wallet.

    Also, what we said above goes for ALL exchanges. Use Bitstamp? Cool! Once you buy bitcoins on Stamp, send the coins to your hardware wallet. The same goes for Kraken, Poloniex, or any other exchange or service that holds your coins!

    What other kinds of wallets can I use?

    Other wallet types are hot wallets. This means they are wallets run on an internet connected computer.

    Android wallets, iOS wallets and desktop wallets are all examples of this.

    How many backups of my seed should I create?

    We recommend keeping at least two backups of your seed in multiple locations.

    You can also laminate your seed to protect against water damage or any other damage.

    Keeping your seeds in fire proof safes can help protect in the event that the storage location is burned down.

    Another option is to put your seed into metal manually using stamps, or using cryptosteel.

    What happens if someone finds my 24 word seed?

    Unless you’re using a 25th word, someone who finds your 24 word seed can sweep your entire wallet.

    Coinbase is a web wallet with a simple design and a number of very useful features that make it excellent for beginners. You can send and receive bitcoins via email and buy and sell bitcoins directly from Coinbase.

    Once you get the hang of things, it is better to move your coins off of Coinbase and into a wallet mentioned above like the Ledger Nano S . Coinbase is a good place to buy bitcoins and learn how it works, but not a good solution for long term storage.

    A full-featured Android app enables access to all account functions on the go. Coinbase’s founders have a proven startup track record and have raised money from very prominent venture capitalists. This gives Coinbase a level of legitimacy unparalleled in the Bitcoin space. They are also one of the only large Bitcoin companies to never suffer a major hack. Click here to sign up.

    Electrum is a software wallet that enables you to set up a strong level of security very quickly. During the simple installation process, you are given a twelve word phrase that will allow you to recover all of your bitcoins in the event that your computer fails. Your wallet is also encrypted by default which helps protect your coins against hackers. Electrum is available for Windows, OSX, and Linux and is our recommended software wallet for beginners. Click here to download the right version for your operating system.

    Bitcoin Wallet for Android

    For those looking for mobility and security, we recommend the simply-titled Bitcoin Wallet mobile app. There is a version for both Android and BlackBerry OS . It is a software wallet, so you retain complete control over your bitcoins. It also works well with QR codes and NFC, making transferring coins to someone else’s phone easier than writing a check. Be sure to backup your wallet (with the included “Backup Wallet” feature) or you risk losing all your coins the next time you get too close to a pool.

    Other Wallets

    We also recommend a few other wallets, but not for the beginning Bitcoin user. If you are up for more of a challenge, Armory is a good choice for those requiring the highest possible security, and the original Bitcoin-Qt client is also trusted and worth learning how to use.

    Now that you have a wallet set up, it’s time to learn how to get some bitcoins .
