You’re in the right place!

The short answer is:

Find a Bitcoin exchange

Trade your local currency, like U.S. dollar or Euro, for bitcoins

For the long answer, read this Bitcoin buying guide and by the end you’ll understand these key points:

How and where to buy bitcoin

How to choose the right exchange

How to secure your coins after you buy

How to avoid scams

Below, we listed exchanges you can use to purchase BTC. We suggest our listed exchanges and doing your own research before making your final decision.

Certain exchanges are simply there to steal your personal information or rob you of your bitcoins.

We conduct intensive research on every exchange we list to filter out any and all dishonest exchanges.

Choosing an Exchange: Which is the Best Bitcoin Exchange?

To select the perfect exchange for your needs, consider these 7 factors.

1. Privacy: Keep Your Information Safe!

Want to buy BTC privately?

You can already cross off a number of payment methods:

Bank transfer
Credit card
Debit card
PayPal
Any other method that requires personally or identifying information

Buying bitcoins with cash or cash deposit is the most private way to purchase bitcoins.

We also have a detailed guide which reveals your options for buying without verification or ID.

2. Limits: Are You Buying a Lot of Coins?

If you need to buy a large amount of bitcoins--say 25 or more--then big brokers or major exchanges are the way to go.

Coinbase has high limits for buying with a bank account.

CoinMama has the highest limits for buying with a credit card.

Most cash exchanges have no buying limits. Limits, however, will vary between individual sellers and are usually lower than online exchanges.

3. Speed: When Do You Need Access to your Bitcoins?

How quickly do you need to convert regular money into bitcoins? Different payment methods deliver your coins at different speeds.

Your first Bitcoin purchase may be time consuming. Once you get everything setup all subsequent purchases will be much faster!

Bitcoin ATMs can be the fastest way to purchase bitcoin if you’re lucky enough to have one in your area. Here's a map to help you out.

Some brokers offer instant buys with bank transfer, credit card, or debit card.

4. Exchange Rate

There is no official Bitcoin price. Use BitcoinAverage or CoinDesk to see the average price of Bitcoin across all major international Bitcoin exchanges and compare that to the price on your chosen exchange.

5. Reputation: Don't Get Scammed!

How long has the exchange been in service? Is the exchange trustworthy? Our Bitcoin exchange reviews can help you to find a trusted exchange.

6. Fees: Are You Getting a Good Deal?

How much does the exchange charge for its services? The fee will vary greatly based on the payment method you choose to use.

Remember to include deposit and withdrawal fees as well as trading fees. Some exchanges will lower their fees if you trade a lot of bitcoins.

7. Payment Method

How can you pay for the bitcoins? Payment method may be the most important factor.

We're sure you already have a payment method in mind that you'd prefer to use. More on that below.

Get a Wallet!

Some exchanges require a Bitcoin wallet before you can buy.

If you don't have a wallet yet, learn how to get a Bitcoin wallet and then come back.

We'll wait for you here ;)

Know your Payment Method?

Payment Methods

We can both agree that this Bitcoin stuff is confusing. Stick with us!

We're about to have you on your way to choosing a payment method and buying bitcoins.

Where to Buy Bitcoin?

Purchase bitcoins online with a credit card, debit card, or bank transfer.
Acquire bitcoins from a Bitcoin ATM near you.
Buy bitcoins with cash locally or via cash deposit.
Convert PayPal to Bitcoin online.

The above was just a brief overview of where you can buy bitcoin. Now, let's get into the details.

In order to buy bitcoins, you’ll need to exchange your local currency, like Dollars or Euros, for bitcoin. Here’s an overview of the 4 most common payment methods:

1. Credit or Debit Card

Credit/debit cards are the most common way to pay online. So, it's really no surprise that many people want to buy bitcoins this way.

Why buy bitcoin with a credit/debit card?

Credit cards are a payment method most people are familiar with; probably the easiest way to buy bitcoins online
Delivery of bitcoins is instant once initial verification is complete

Why NOT buy bitcoin with a credit/debit card?

High fees; if you're patient and not in a rush to buy then use a bank transfer for lower fees
Not a private way to buy; your ID will be required to buy with a credit card

A few places to buy bitcoins online with a credit card are:

Bank Account or Bank Transfer

Bank transfer is one of best ways to buy bitcoins in most countries.

Why buy bitcoins with bank account/transfer?

Good way to buy large amounts of bitcoins
Using a bank transfer will usually result in the lowest fees, so you can get a great price on your purchase

Why not to buy bitcoins with bank account/transfer?

Usually requires ID verification, so not a good choice for privacy
Slow; in the USA, bank transfers can take up to 5 days to complete

Some of the best ways to buy bitcoins with your bank account:

Cash deposit is often the fastest and most private ways to buy bitcoin. You can usually receive your bitcoins within a couple hours.

What are cash exchanges good for?

Can be more private since in some cases no personal information is required
Can be nearly instant; no need to wait 5 days for a bank transfer to process

What are cash exchanges bad for?

Privacy comes at a cost; cash exchanges often have price 5-15% above market rate
Easier to get scammed or robbed; need to be on alert and follow the exchange's rules

Some of the best places to buy bitcoin instantly with cash:

Note: There is no easy way to buy bitcoin at Walmart. We get asked this A LOT!

There are Bitcoin ATMs all around the world that let you purchase bitcoin with cash.

You simply insert cash into the machine, and get bitcoins sent to your wallet.

Use Coin ATM Radar to find a Bitcoin ATM near you.

What are Bitcoin ATMs good for?

Can be more private since in most cases no personal information is required
If you have an ATM in your area it can be a convenient and fast way to buy coins

What are Bitcoin ATMs bad for?

Privacy comes at a cost; Bitcoin ATMs often have a 5-15% premium above market rate

There is no way to directly buy bitcoins with PayPal. Under PayPal’s terms and conditions merchants are not allowed to sell bitcoins for PayPal.

I really recommend not buying bitcoins with PayPal. The fees are really high. Chances are that your PayPal is connected to your credit card or bank account, which can be used to buy at much lower fees.

However, there are a few hacks to get around this. You can buy other digital items with PayPal and sell those items for bitcoin. It's all explained in our guide on how to buy bitcoins with PayPal.

Why buy bitcoins with PayPal?

If you already have a balance, it can be an easy and fast way to convert PayPal to bitcoins

Cons of buying bitcoins with PayPal

Fees are over 12%; much better to just buy with a credit card or bank account

Frequently Asked Questions

If you're still a bit confused, that's okay. Buying bitcoins is hard, but that's why I built this site, to make it easier!

If you still need help, I hope this FAQ will help to answer any remaining questions.

When is the Right Time to Buy?

As with any market, nothing is for sure. Bitcoin is traded 24/7 and its price changes every second.

Use tools like Bitcoin Wisdom or Cryptowatch to analyze charts from other Bitcoin trading sites. These charts will help you understand Bitcoin’s price history across the many global Bitcoin exchanges.

Why Does Buying Bitcoin Take So Long?

Long wait times are usually a problem with existing payment systems, not with Bitcoin itself.

Bitcoin transactions only take about 10 minutes to confirm. Bank transfers in the U.S., for example, can take up to five days to complete.

Bitcoin transactions can be confirmed as quickly as 10 minutes; it’s rare to experience a delay longer than one hour.

This means that a merchant can’t release bitcoins to a customer until five days have passed unless they're willing to take on risk.

Can You Sell Bitcoins?

Yes, of course! Most exchanges that let you buy bitcoins also let you sell (for a fee of course).

Why Do I Need to Upload my ID for Some Exchanges?

This is due to Know Your Customer (KYC) laws which require exchanges to record the real world identity of their clients.

Can Anyone Buy Bitcoin?

Bitcoin requires no permission to use or buy.

You will have to check the legality of Bitcoin in your country. In most countries Bitcoin is legal!

Should I Buy Physical Bitcoins?

Physical bitcoins are physical, metal coins with a Bitcoin private key embedded inside.

We recommend that you stay away from physical bitcoins unless you’re a numismatist.

While physical coins sound like a good idea, they force you to trust the honesty of the creator of the coin. The creator could create two copies of the private key.

Unless you immediately open and withdraw the digital bitcoins from your physical bitcoin, the creator could at any time steal the funds it contains.

Can I Buy Partial Bitcoins?

Each bitcoin is divisible to the 8th decimal place, meaning each bitcoin can be split into 100,000,000 pieces. Each unit of bitcoin, or 0.00000001 bitcoin, is called a satoshi.

Most exchanges let you buy as little as $5 worth of bitcoins at a time.

Why Should I Buy Bitcoin Instead of Mining?

A long time ago anyone could mine bitcoins on their computer at home. Today, only specialized computer hardware is powerful enough to do this.

Think about it like this:

Should you buy gold or mine gold? Well, to mine gold you need big powerful machines, a lot of time, and money to buy the machinery. This is why most people just purchase gold online or from a broker.

So Bitcoin is no different.

You should just buy some if you want coins without trying to mine.

Do I need a Bitcoin Account Before Buying?

With Bitcoin, there are not really accounts.

Instead, you should have a Bitcoin wallet. If you want to store bitcoins, then a wallet is where you keep them.

In Bitcoin these wallets are not called an account but a wallet functions almost the same way. The only difference is you are responsible for the security if your wallet rather than placing the security in the hands of a bank or trust.

How do I check if I received a Bitcoin payment?

Why Would Someone Even Want to Buy Bitcoins?

There are many reasons people want to own bitcoins.

Many people like to purchase some and put them to the side in the hopes that they will be worth more in the future.

Many people are using bitcoins to remit money to their families from out of the country. Right now, Bitcoin is one of the cheapest ways to do this.

People also use Bitcoin to buy stuff online. Big companies like Microsoft, Dell, Newegg and Overstock all accept bitcoins.

Bitcoin is also very unique compared to other markets in that it trades 24 hours a day and never stops. Most stock markets only open on weekdays from 9 AM to 5 PM. So many traders buy and sell bitcoins because it is a fun and fast market to trade.

Can I Buy Bitcoin Stock?

Bitcoin itself is not a stock despite it functioning somewhat like one. You can’t buy bitcoins through a traditional stock fund and instead have to buy bitcoins yourself. This may change in the future if a Bitcoin ETF ever gets approved.

What Happens When you Purchase Bitcoins?

Bitcoins are actually just secret digital codes. When you buy bitcoins, the seller is using a wallet to transfer the ownership of the coins to you. Once your purchase is complete, the codes are now owned by you and not the seller.

Why Are the Chinese Buying So Much BTC?

It seems the Chinese really like Bitcoin’s properties such as its sound monetary policy and that it can be used anywhere in the world. Bitcoin's volatility also makes it interesting for speculative traders.

Is Bitcoin Legal?

Bitcoin is legal in nearly every country. Only a few countries have actually banned the use of bitcoins. Before you buy, make sure you double-check the legal status of Bitcoin in your country.

Why do I need to buy bitcoins before buying most altcoins?

Bitcoin functions as the "reserve" currency of cryptocurrency. So it is very hard to buy other coins without first buying bitcoins. Once you purchase the bitcoins you can convert the bitcoins into other cryptocoins. This is mostly because Bitcoin has very good liquidity and is traded on every cryptocurrency exchange. So most coins are traded against Bitcoin rather than the US dollar or other fiat currencies.

Am I Anonymous when I Buy?

Bitcoin is not anonymous but rather pseudonymous. All Bitcoin transactions are public but it is not always known the real identity behind any give Bitcoin address.

Can I use Multiple Exchanges?

If the limits on one exchange are to low you can simply open an account with another exchange to give yourself the ability to buy more.

You can signup, join, and use as many Bitcoin exchanges as you want that are available in your country.

Do I need to Pay Taxes on Bitcoin?

In most countries you will need to pay some kind of tax if you buy bitcoins, sell them, and make a gain. In the US you must do this on every transaction.

Be sure to check with your country’s tax authorities to make sure you are paying all the required taxes on your bitcoin use.

What Other Ways can I Get Bitcoins Besides Buying?

Just like any other form of money, you can get bitcoins by requesting from your employer to be paid in bitcoins.

Avoiding Bitcoin Scams: Don't Lose Money!

I've been using Bitcoin for 3+ years. I've never fallen victim to a single scam. Follow the tips explained here and you'll greatly reduce your chances of losing money.

There are many scams related to Bitcoin. Scammers target new Bitcoiners and less tech-savvy users. Follow these basic rules in order to avoid Bitcoin scams:

Study your intended exchange and make sure it’s trustworthy. Search forums like Reddit for the experiences of other users.

You can also use our Bitcoin exchange reviews to get in depth information about certain exchanges. If you don’t find your intended exchange listed on this site, extra caution and research is advised as it may be a scam!

Check Ratings

If you’re using a peer-to-peer exchange like LocalBitcoins or Wall of Coins, check the seller’s feedback. If most of their feedback is positive, your trade is more likely to go through without issues. If a seller has lots of negative feedback, it’s best to simply stay away and find a more reliable seller.

Use Escrow

Many scammers will try an approach like this:

“Send me bitcoins, and once I get the bitcoins I’ll pay you on PayPal!”

Don’t ever agree to a trade like this. Bitcoin payments are irreversible, so if you send first the scammer can simply not pay you and keep their bitcoins.

PayPal can't force the scammer to pay either, due to the pseudonymous nature of Bitcoin which doesn’t record the identity of a payment’s sender or recipient. This would leave you with no way to get your bitcoins back.

Stay Away from Bitcoin investments

Any service that claims to pay interest on bitcoins or increase your bitcoins is likely extremely risky or an outright scam. If it sounds too good to be true, stay away.

Be Careful with Altcoins

What are altcoins? Altcoins are cryptocurrencies other than Bitcoin.

Altcoins are traded globally on hundreds of exchanges. Avoid throwing money into coins which are experiencing a sudden and dramatic spike in price and volume. Such moves, especially in insignificant coins with otherwise thin volume and flat price action, are likely to crash fast.

Secure your Coins

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

Here are two examples where users got screwed by leaving bitcoins with a third party:

So, do yourself a favor:

Get yourself a Bitcoin wallet and control your own coins. For large amounts of bitcoins, we recommend cryptocurrency hardware wallets. Hardware wallets are small, offline devices that store your bitcoins offline and out of reach from hackers and malware.

Why? It's pretty simple:

Hardware wallets are the easiest way to securely store bitcoins and easy to backup
Less margin for error; setup is easy even for less technical users

Check out the Bitcoin hardware wallet comparison chart below:

Mining hardware comparison

Below are statistics about the Bitcoin Mining performance of ASIC hardware and only includes specialized equipment that has been shipped.

GPUs, CPUs and other hardware not specifically designed for Bitcoin mining can be found in the Non-specialized_hardware_comparison.

Mhash/s = millions hashes per second (double sha256 raw speed performance; may not be very energy efficient with some models)
Mhash/J = millions hashes per joule (energy efficiency; 1 joule of energy is 1 watt during 1 second: 1 J = 1 W*s)
W = watt (maximum power consumption, i.e. energy per unit of time: 1 W = 1 J/s)

Be sure to research any of these vendors and machines intensely before spending any money.

Best Bitcoin Mining Hardware for 2018 – Bitcoin Miner Reviews

The following page reviews the best hardware available today in order to make some sort of a profit with Bitcoin mining.

If you’re completely new to Bitcoin mining please read our “Is Bitcoin mining still profitable?” post before moving on. It will give you a good idea about the profitability of mining and will make you think twice before entering this very competitive niche.

If however, you are aware of the competitive nature of Bitcoin mining and still want to get in the game, here you will be able to find the best Bitcoin mining hardware available. The good news is that there are not many mining hardware companies left that make ASIC miners so choosing will probably be easy. That’s also the bad news. Even though many websites state long lists of Bitcoin mining hardware, only a handful of mining rigs can deal with the rising Bitcoin mining difficulty that’s out there these day.

How to compare Bitcoin miners

Below is a side by side comparison of all relevant miners. Underneath the table you’ll be able to see a summarized review of each of the miners. Keep in mind that in order to see how profitable you can be with any Bitcoin miner you’ll need to use a Bitcoin mining calculator based on your electricity cost, the Bitcoin exchange rate and the increase in difficulty throughout time. Since not all of these variables are known you will have to guess some as best as you can.

Antminer S5 Bitcoin Miner Summarized Review

The Antminer S5 is the entry level Bitcoin miner for someone who isn’t ready to part away with more than a few hundred bucks. Users who have purchased it seem mostly pleased with the device. However this is an outdated device and with today’s mining difficulty and decreasing block reward you won’t make more than 0.05 BTC each money in revenue. This means you’ll need to run it for about one year and 8 months to get a full Bitcoin. Some customers also complained about the device being too noisy, but that’s just how a miner works – it’s loud and hot.

Avalon 6 BitcoinMiner Summarized Review

The Avalon 6 is a great contender for both S5 and S7 AntMiners. From the small number of reviews that can be found online people are saying that it’s not nearly as loud as your usual miner and the hash rate is pretty reasonable. However at the current price tag I see little reason to choose it over the competition, it’s $100 more than the S7 that brings to the table superior results.

Antminer S7 Bitcoin Miner Summarized Review

The Antminer S7 was the raining champion up until a few months ago. Even at today’s difficulty levels and with the block reward halving you can still make 0.15BTC a month. It’s not a lot at the moment but if the Bitcoin price continues to rise it may be a profitable investment.

However I wouldn’t suggest buying this rig due to the fact that it’s neither here nor there. It’s too expensive for an entry-level device and it’s too weak to generate any substantial amount of Bitcoins. Users who bought the device seem generally happy with it however it was first introduced on August 2015, so it’s not that new.

Antminer S9 Bitcoin Miner Summarized Review

The most advanced and most efficient Bitcoin miner today is the Antminer S9. If you’re serious about Bitcoin mining this is your rig. At the current difficulty this miner can mine around 0.02 Bitcoins every month which makes it seem like it would break even within a year. However we did not take into account the electricity costs, pool fees and hardware cost. Not to mention the fact the difficulty can rise and the Bitcoin price can drop.

It seems that even though this is the toughest miner out there, there’s only a small amount of time until it too will become outdated. Until that happens though, it looks like a pretty reliable piece of equipment.

Antminer R4 Bitcoin Miner Summarized Review

The Antminer R4 is intended for hobby mining – basically people who want to mine Bitcoins at home. Even though it can’t compete with the S9 it will probably be a good contender for the S7. The main advantage it has over other miners is the fact that it is has a specialized cooling unit that is much quieter than any other Bitcoin miner out there – since it’s made for a home environment.

According to our mining calculator this miner should break even in about 12 months. However if Bitcoin’s price continues to rise this miner may yet yield a good return on investment.

Avalon 7 Bitcoin Miner Summarized Review

The Aavalon 721 (or Avalon 7 as it is known commonly) is the latest Bitcoin miner supplied by Avalon in late 2016. It has a lower price tag than most of the advanced miners but is also less powerful. It seems to be a good choice for people who are looking for a cheaper entry level miner and don’t want to go for an Antminer S7.

According to our calculations, this miner should break even in about 24 months, making it a pretty risky investment. You can also connect up to 5 Avalon 721s in a row creating a powerful 30 TH/s mining rig.

Antminer T9 Bitcoin Miner Summarized Review

The Antminer T9 is a more reliable, cheaper version of the successful S9 model. However, the T9 uses almost 30% more power than the S9 making it much less attractive in terms of return on investment. If you want to get up and mining as soon as possible and reliability is more important to you than efficiency, then we’d say the T9 is a reasonable choice. If you don’t pay for power and just want a good, fast miner you can “fire up and forget,” the Antminer T9 will fit the bill nicely.

Ethereum Mining Hardware

Do you want to mine Ethereum?

Using an efficient Ethereum mining hardware will significantly reduce your electricity bills and cut down your costs. This article will help you learn more about the best Ethereum mining hardware.

Note: Before you get hardware make sure you have Ethereum mining software, an Ether mining pool, and an Ethereum hardware wallet like the Ledger Nano S for secure storage of Ether.

If you just want Ether then just buy Ethereum. Mining has a lot of setup costs and some technical knowledge is required.

What is a GPU Ethereum Miner?

In order to mine Ethereum, you will need specialized hardware known as graphics processing unit (GPU).

Ethereum’s developers originally intended for it to be mined on computer CPUs but miners later discovered that GPUs gave them more hashing power.

So, in the most simplest of terms: a GPU is a specialized Ethereum mining computer.

How can you find the best GPU and rig?

Some GPUs have a higher hash rate than others, while some use more electric power as well.

In choosing the most efficient GPU the most important thing is striking a balance between how powerful you want your rig to be and how much you are willing to spend on the GPU itself and the electricity.

Many of these costs will vary by country. Is it cheap to buy GPUs in your country?

Since most GPUs are sold on Amazon and eBay, if you live in a country where those retailers ship to then you will likely have an easier time getting the GPUs.

Also, what is the cost of electricity in your country?

Electricity costs are the deciding factor for most miners. As we have seen with Bitcoin mining, miners in China, Iceland, and other places with cheap electricity have a huge advantage!

Most efficient GPUs on sale

Now that you understand the factors that make GPU rigs good, here is a list and brief description of the most efficient GPUs on sale.

Note that the power costs per day numbers used below were based on the global average cost of electricity and the price of Ether on September 16, 2016.

Radeon R9 295X2

The Radeon R9 295X2 has by far the highest hash rate (46.0 MH/s) of the Ethereum GPUs on the market and will cost you $600. It has a power cost per day of about $1.44, a return per day of about $1.61 and a cost per MH/s of $13.04. This gives a return per year of $586.43.

Radeon R9 HD 7990

A Radeon R9 HD 7990 will cost you $680. Its power cost per day is lower than the R9 295X2 at $1.08 but its hash rate is significantly lower at 36 MH/s. Its return per day is $1.29 while its cost per MH/s is $18.89, giving it a return per year of $469.40.

Radeon RX 480

The Radeon RX 480 is most arguably the most economical in terms of cost and saving electricity. Its power cost per day is significantly lower than the two that I have mentioned at $0.4320. Its hash rate is 25.0 MH/s, meaning its cost per MH/s is $7.96. This gives a return per day of $1.21 and therefore a return per year of $440.91. Radeon RX 480 will cost you $199.

Radeon RX 470

A Radeon RX 470 has a modest hash rate of 24.0MH/s. Its power cost per day is exactly the same as the Radeon RX 480 at $0.4320. Its cost per MH/s is $9.13, giving it a return per day of $1.15 and a return per year of $418.16. Radeon RX 470 will cost you $219.

Now that you know the best Ethereum mining hardware, get a secure wallet for your Ether.

If you don’t want to mine you can always just buy some Ether online.

Just Want Ether?

If you just want ether, mining is NOT the best way to obtain coins.

Buying ether is the EASIEST and FASTEST way to get ether.

Get $10 worth of free ether when you buy $100 or more at Coinbase.

Bitcoin grafikkarte

Bitcoin mining pools are a way for Bitcoin miners to pool their resources together and share their hashing power while splitting the reward equally according to the amount of shares they contributed to solving a block.

A "share" is awarded to members of the Bitcoin mining pool who present a valid proof of work that their Bitcoin miner solved. Bitcoin mining in pools began when the difficulty for mining increased to the point where it could take years for slower miners to generate a block.

The solution to this problem was for miners to pool their resources so they could generate blocks quicker and therefore receive a portion of the Bitcoin block reward on a consistent basis, rather than randomly once every few years.

Network Consensus

If you solo-mine, meaning you do not mine with a Bitcoin mining pool, then you will need to ensure that you are in consensus with the Bitcoin network. The best way is to use the official BitCore client.

If you participate in a Bitcoin mining pool then you will want to ensure that they are engaging in behavior that is in agreement with your philosophy towards Bitcoin.

For example, some rogue developers have threatened to release software that could hard-fork the network which would likely result in tremendous financial damage.

Therefore, it is your duty to make sure that any Bitcoin mining power you direct to a mining pool does not attempt to enforce network consensus rules you disagree with.

Segregated Witness

When segwit is activated, you will want to be able to mine and relay segwit-style blocks. The following mining software has been upgraded to support segwit.

Please note that software that supports the GetBlockTemplate (GBT) RPC must be upgraded to support the BIP9 and BIP145 changes to GBT. All the programs linked above that support GBT have been upgraded.

Segwit is already activated and enforced on testnet, so you may find it useful to test your infrastructure upgrade by mining with some small amount of hashrate on testnet. Alternatively, Bitcoin Core 0.13.1’s regression test mode (regtest) also supports segwit by default.

Bitcoin Mining Pools

There are many good Bitcoin mining pools to choose from. Although it's tempting to pick the most popular one, it's better for the health of the network to mine with smaller pools so as to avoid potentially harmful concentration of hashing power.

The hash rate distribution is best when split among more Bitcoin mining pools.

Bitcoin Mining Pool Hash Rate Distribution

Bitcoin Mining Pool Options

For a fully decentralized pool, we highly recommend p2pool.

The following pools are believed to be currently fully validating blocks with Bitcoin Core 0.11 or later:

BTCC: BTCC is a Bitcoin exchange, wallet, and mining pool located in China. Its mining pool currently controls around 15% of the network hash rate.

Slush Pool: Slush Pool is run by Satoshi Labs, a Bitcoin company based in the Czech Republic. Slush Pool was the first mining pool and maintains around 7% of the network hash rate.

Antpool: [WARNING] - Bitmain operates Antpool and some consider them to be a malicious actor in the Bitcoin ecosystem because of the AntBleed scandal where they were intentionally including malware within mining equipment they sell. In a corporate communication, Bitmain claimed this was a feature and not a bug. This malware would enable Bitmain to remotely shut down equipment of customers or competitors thus increasing their own profitability. Additionally, such behavior could pose a risk to the entire Bitcoin network.

Eligius: Eligius was one of the first Bitcoin mining pools and was founded by Luke Dashjr, a Bitcoin Core developer. Today, the pool controls just under 1% of the network hash rate.

BitMinter: BitMinter, once one of the largest Bitcoin mining pools, now controls less than 1% of the network hash rate.

Kano CKPool: Kano CKPool was founded in 2014 and currently has around 3% of the network hash rate under its control.

F2Pool: F2Pool is the second largest Bitcoin mining pool, with around 25% of the network hash rate. Its user interface is in Chinese, making it difficult for English speakers to join.

BW Pool: BW Pool controls around 7% of the network hash rate. Like F2Pool, its user interface is in Chinese, making it difficult for English speakers to join.

Bitfury: Although seen publically in block explorers and hash rate charts, BitFury is a private mining pool and cannot be joined.

Bitcoin Mining Pool Payment Methods

Calculating your share of the bitcoins mined can be complex. In an ongoing effort to come up with the fairest method and prevent gaming of the system, many calculation schemes have been invented. The two most popular types are PPS and DGM. PPS, or 'pay per share' shifts the risk to the mining pool while they guarantee payment for every share you contribute.

PPS payment schemes require a very large reserve of 10,000 BTC in order to ensure they have the means of enduring a streak of bad luck. For this reason, most Bitcoin mining pools no longer support it.

One of the few remaining PPS pools is EclipseMC. DGM is a popular payment scheme because it offers a nice balance between short round and long round blocks. However, end users must wait for full round confirmations long after the blocks are processed.

PPS: The Pay-per-Share (PPS) approach offers an instant, guaranteed payout for each share that is solved by a miner. Miners are paid out from the pools existing balance and can withdraw their payout immediately. This model allows for the least possible variance in payment for miners while also transferring much of the risk to the pool's operator.

PROP: The Proportional approach offers a proportional distribution of the reward when a block is found amongst all workers, based off of the number of shares they have each found.

PPLNS: The Pay Per Last N Shares (PPLN) approach is similar to the proportional method, but instead of counting the number of shares in the round, it instead looks at the last N shares, no matter the boundaries of the round.

DGM: The Double Geometric Method (DGM) is a hybrid approach that enables the operator to absorb some of the risk. The operator receives a portion of payouts during short rounds and returns it during longer rounds to normalize payments.

SMPPS: The Shared Maximum Pay Per Share (SMPPS) uses a similar approach to PPS but never pays more than the Bitcoin mining pool has earned.

ESMPPS: The Equalized Shared Maximum Pay Per Share (ESMPPS) is similar to SMPPS, but distributes payments equally among all miners in the Bitcoin mining pool.

RSMPPS: The Recent Shared Maximum Pay Per Share (RSMPPS) is also similar to SMPPS, but the system prioritizes the most recent Bitcoin miners first.

CPPSRB: The Capped Pay Per Share with Recent Backpay uses a Maximum Pay Per Share (MPPS) reward system that will pay Bitcoin miners as much as possible using the income from finding blocks, but will never go bankrupt.

BPM: Bitcoin Pooled mining (BPM), also known as "Slush's pool", uses a system where older shares from the beginning of a block round are given less weight than more recent shares. This reduces the ability to cheat the mining pool system by switching pools during a round.

POT: The Pay on Target (POT) approach is a high variance PPS that pays out in accordance with the difficulty of work returned to the pool by a miner, rather than the difficulty of work done by the pool itself.

SCORE: The SCORE based approach uses a system whereby a proportional reward is distributed and weighed by the time the work was submitted. This process makes later shares worth more than earlier shares and scored by time, thus rewards are calculated in proportion to the scores and not shares submitted.

ELIGIUS: Eligius was designed by Luke Jr., creator of BFGMiner, to incorporate the strengths of PPS and BPM pools, as miners submit proofs-of-work to earn shares and the pool pays out immediately. When the block rewards are distributed, they are divided equally among all shares since the last valid block and the shares contributed to stale blocks are cycled into the next block's shares. Rewards are only paid out if a miner earns at least. 67108864 and if the amount owed is less than that it will be rolled over to the next block until the limit is achieved. However, if a Bitcoin miner does not submit a share for over a period of a week, then the pool will send any remaining balance, regardless of its size.

Triplemining: Triplemining brings together medium-sized pools with no fees and redistributes 1% of every block found, which allows your share to grow faster than any other Bitcoin mining pool approach. The administrators of these Bitcoin mining pools use some of the Bitcoins generated when a block is found to add to a jackpot that is triggered and paid out to the member of the pool who found the block. In this way, everyone in the pool has a better chance to make additional Bitcoins, regardless of their processing power.

Nvidia GPU Mining Profit Calculator Software

Here is a nice and useful software for everyone using Nvidia GPUs for mining crypto coins, especially for people that have built mining rigs based on the very popular for mining GeForce GTX 750 Ti video cards. The tool is called Profit Calculator and in open source, being developed by a user called KBomba. It queries different crypto exchanges such as Bittrex, Mintpal and Cryptsy for coin prices, uses services like WhatToMine, CoinTweak and CoinWarz for the current coin difficulty and block rewards and also checks Nicehash for their current prices as well as PoolPicker for the most profitable pools. The result you get is a list based on profitability that includes not only the most profitable coins to mine, but also the most profitable multipools as well with an estimate on the expected revenue.

The hashrate values that are preset in the tool by default are for a single GTX 750 Ti GPU, but you can change them for other cards if you know the hashrate values of your hardware for the different algorithms. This actually makes the tool useable not only for Nvidia, but also for AMD-based mining rigs as well, though you should first check what hashrate will your hardware be able to provide in order to be able to get more accurate results for what your earnings should be. So do give the tool a try, it can be quite useful even if the results may not always be absolutely accurate, you can still get a pretty good idea about the current market and coin profitability.

Auch ein Internetanschluss wird zum Sammeln von Bitcoins mit Hilfe eines Bitcoin Miner benotigt.

Welche Grafikkarten eignen sich mits Bitcoin Miner?

Um ein twee Grafikkarten zu benennen und damit eine gute Voraussetzung zu schaffen, geht es nun ter diesem Abschnitt. Diegene Asus GeForce GTX Titan Z 12GB GDDR5 hat sich indien sehr gute und damit diegene liefste Grafikkarte erwiesen. Diese ist zwar rechtspraak teuer te der Anschaffung aber beim Bitcoin einsammeln, wird sich diese Ausgabe sehr schnell wieder lohnen. Diese Grafikkarte ist nicht sehr laut und hat eine sehr gute Ausstattung. Vor allem aber diegene Leistung wird jeden Kaufer uberzeugen. Denn diese liegt hier bei vollen 100 Prozent. Indien nachstes muss diegene Asus GeForce GTX 780 Ti Matrix Platinum 3GB GDDR5 genannt werden. Diese verfugt uber ahnliche Eigenschaften wie diegene vorherige aber ist weniger teuer. Diegene Grafikkarte ist etwas lauter. Auch diegene Ausstattung fallt etwas geringer aus. Diese Grafikkarte eignet sich dennoch sehr gut um Bitcoins zu bekommen. Diese beiden Karten von Asus liegen ganz weit vorn und eine Radeon Karte schlie?t sich dann an. Hierbei handelt es sich um diegene PowerColor Radeon R9 290X LCS OC 4GB GDDR5 .

Worin liegt der Unterschied bei Bitcoin Miner?

Diegene Technik ist bei einem Bitcoin Miner entscheidend. So muss diegene verwendete Grafikkarte unbedingt uber einen eigenen Kuhler verfugen. Der wichtigste Bestandteil ist jedoch stropdas System mit dem diegene Hardware lauft. So finden sich heutzutage ASIC Systeme. Diese werden aber noch nicht sehr lange angeboten und sind daher sehr begehrt. Vor diesem System gab es noch diegene GPU Systeme, diegene aber sehr langsam waren.
