Will 2017 be Profitable for Bitcoin Mining?

Bitcoin Mining Hardware Comparison

Currently, based on (1) price per hash and (2) electrical efficiency the best Bitcoin miner options are:

AntMiner S7

AntMiner S9

Bitcoin mining during its early days were generally called as a gold rush. Bitcoin, an invention of Satoshi Nakomoto's, "a peer-to-peer electronic cash system,” opened up an entirely new perimeter, not just of freedom but of profit. People with a strong interest in such things were first to stake their claim, namely cypherpunks, cryptographers, technically-minded libertarians and assorted hackers.

But is there still gold in them thar hills?

From a few of early enthusiasts, it is with certainty that Bitcoin mining has advanced into a cottage industry to a specialized industrial-level venture. The easy money was taken out long ago and the rest are hidden under the cryptographic equivalent of miles of hard rock.

To be able to profitably excavate bitcoins nowadays, you need to have specialized, high-powered machinery. While it is technically possible for anyone to mine, those with underpowered setups will spend more money on electricity than have money generated through mining.

Common Mining Terms

To further understand Bitcoin mining, it helps to know a few basic technical terms:

Block: a group of Bitcoin transactions, as collected from current pending transactions and entered into an ever-growing record of blocks (aka “the blockchain”) by a miner. A new block is created on average every ten minutes.

Proof of Work Hashing: this is the function miners perform in order to define a new block. PoW hashing ensures the proper function of the Bitcoin blockchain. Miners compete to solve a cryptographic “puzzle,” known as a hash. There are no shortcuts in this process, which can only be solved with raw computational power. By correctly hashing the current block, miners prove their investment of work and are rewarded with a certain number of newly-created bitcoins.

Block Reward: the number of newly-created bitcoins. This number was initially set to 50, halved to 25 in late-2012 and will halve again to 12.5 in mid-2016. This halving process continues, approximately every four years (or every 210,000 blocks), until all 21 million bitcoins are created. This is the only way in which new bitcoins can be created; by miners according to the code’s rate and limit.

Hashrate: a measure of a miner’s computational power. The higher their relative power, the more solutions (and hence, block rewards) they’re likely to find. Initially measured in hash per second (H/s), due to the increasing speed of mining hardware. H/s was soon commonly pre-fixed with SI units as follows:

Kilohash = KH/s (thousands of H/s), then

Megahash = MH/s (millions of H/s), then

Gigahash = GH/s (billions of H/s), then

Terahash = TH/s (trillions of H/s), and even

Petahash = PH/s (quadrillions of H/s).

Difficulty: with hashrate shooting up over the years, it would seem blocks would be found by miners ever more rapidly. Bitcoin’s Difficulty measure is what prevents this from happening, ensuring blocks are found roughly every 10 minutes. When total hashrate rises, the Difficulty of POW hashing adjusts upwards - and the inverse also applies. Difficulty auto-adjusts every two weeks (or 2016 blocks).

BTC / XBT exchange rate: the current fiat price of Bitcoin; critical for calculating profitability.

W/xHash/s: Watts per hashrate per second. Electricity is the major on-going cost of Bitcoin mining. The price paid per Watt will greatly influence profitability.

Mining Pool: unless you command a tremendous hashrate, your odds of solving a block by yourself (i.e. “solo-mining”) are extremely low. By banding together with other miners in a so-called pool, your combined odds of solving a block rise proportional to the pool’s total hashrate. Whenever they solve blocks, pools reward individual miners according to their contributed hashrate (minus commissions and the like).

Calculating Mining Profitability

Having these terms in mind, it’s viable to calculate the current profitability of Bitcoin mining for your circumstances. Bear in mind that the future profitability of mining cannot be reliably predicted. This is because of the ever-changing nature of the Difficulty modifier and the BTC price, in particular.

To start, we must select a suitable ASIC mining rig. To help in selection, the Bitcoin Wiki provides a handy mining hardware comparison: We'll select for our example the AntMiner S7 which is pretty much the cutting edge of mining tech and is a modern mining rig that offers a good hashrate for its power consumption. The S7 in Amazon is available for $609 and only $450 from BitMain, exclusive of shipping. $150 or so is added for the power supply units.

Next, we need to enter the S7’s specs and cost, as well as other info such as power cost and pool fees, into a suitable number-cruncher. CoinWarz.com offers a good mining profitability calculator, which automatically fills in the current BTC price, Difficulty and block reward info.

As a standard in China, the default power cost we will use is 10c (USD), but possibly to be much higher elsewhere. Check worldwide electricity prices or your utility bills for the exact price to know your own power cost. The 2.5% Pool Fee is for AntPool. There is generally lower or no fees for smaller pools but remember that they will seldom find blocks. Various pools’ fees and reward structures are compared in this list.

After all the needed info is registered, click Calculate for the profitability result:

Not a bad result! $800 per year and you can use the miner’s excess heat to warm your home.

The American Scenarios

Exciting as it seems, let’s first recompute the average power cost per kWh in the USA (

12.5c) and the 12.5 BTC block reward which becomes the new standard in 45 days or so (see Bitcoin Clock for an up-to-date estimate):

Given the difficulty and price hold steady and by the looks of it, it turns out that in every year, an average American miner can only make $500. But, this could be an unsafe assumption! Bitcoin’s average hashrate surprisingly climbed by a whopping 30 percent by the time this article is being written.

The compensatory Difficulty spike, expected on the day following reports of this spike, completely alters the previous equation:

If we bump up the Difficulty in the mining calculator by the corresponding 30%, all profit evaporates! $500 is lost over one year’s worth of mining.

Unexpected Profit Loss: Difficulty Spikes, Price Crashes, Equipment Failures, Power Cuts, Shipping Delays & More

The aforementioned scene works as a perfect picture of the risks present in the Bitcoin mining. There is a possibility that even some big, corporate miners will be injured from such a steep Difficulty spike. Unless home miner has access to free or very low-cost electricity, it really has zero chance to compete in such challenging environment.

Remember also that the rate of degeneration in Bitcoin hardware is tremendously fast! One should be knowledgeable that during (pre-) ordering equipment, potential manufacturing, shipping, customs or other delays could be very costly in the end as difficulty rises or price falls during the interim.

There are many of other inaccurate things, and such downside risks must always be considered into any concept business plan.

The Chinese Scenarios

For interest’s sake, let’s check the scenario of Chinese miners, who represent the majority of Bitcoin mining power for good reason. The results may help us better predict the post-halving Bitcoin environment, as this article attempts to do.

Hobby Miners

Some Chinese regions are over-supplied with electricity, which are subsidized in many instances. Because of this, low power cost is made and we’ll assume to be 7c for a miner in the right province. To add, a number of mining hardware is invented in China resulting to likely be bought cheaper (and received sooner) by locals of the Middle Kingdom. We’ll assume a ¾ hardware price.

Before the Difficulty spike, a small-time Chinese miner with a single S7 connected to AntPool could have made over $1000 annually. That’s twice the profit of their American counterpart!

After the halving and Difficulty spike, the same miner would lose about $40 per year. For a Bitcoin lover, this is an easily-acceptable loss.

Industrial Miners

Cheap power sources are present in remote provinces so large-scale mining operations will situate closely there. One popular option is hydroelectric power from dams. From such enterprises we can assume a very low power cost, let’s say 5c. These operations also buy hardware in volumes so assuming they get S7s at $325, which is only half the price. One thousand S7 units seems a reasonable number, which permits us to simply add three zeros to hash rate, hardware and power costs. Lastly, these setups often run their own pools and so we’ll suppose zero pool fees.

The operation would net $1.4m annually, before the halving and Difficulty spike.

The operation would profit by about $200k annually, after the halving and Difficulty spike.

Given the initial hardware investment of $325k, a profit of $200k doesn’t look great. It can be seen that marginal mining operations will be forced out of business post-halving given the other costs involved in mining, such as property, salaries, maintenance, etc. Only those with the latest and greatest hardware and the cheapest electricity are likely to pull through. Bitcoin price is the only wild card. It’ll allow less efficient miners to keep the lights on for longer, if it rises sufficiently.

Conclusion

For an average home miner it will be a struggle to regain the cost of mining hardware and electricity. In this current given circumstance, profitability is highly unlikely. Once ASIC mining hardware innovation reaches the point of diminishing returns, the situation may improve in future. That, together with cheap, hopefully sustainable power solutions may once again make Bitcoin mining profitable to small individual miners around the world. The decentralization of the Bitcoin network, will also greatly improve hardening it against legislative risk.

Bitcoin-Mining

Bitcoins werden im Netzwerk geschöpft, wobei neue Bitcoins durch das sogenannte Bitcoin Mining erzeugt werden. Prinzipiell kann also jeder Bitcoin-Nutzer mit einer Bitcoin-Adresse mit Bitcoin Mining Geld verdienen. Ganz so simpel ist das leider nicht, deshalb erklären wir im Folgenden wie der Mining-Prozess funktioniert und wie man davon profitieren kann.

Mining ist nichts anderes als die Erfüllung einer benötigten Kontrollfunktion im Bitcoin-Netzwerk, da keine Bank und auch kein Finanzdienstleister im System vorhanden ist, der den reibungslosen Ablauf der Online-Zahlungen überprüft. Wichtig ist dabei vor allem, dass kein Bitcoin doppelt ausgegeben werden kann, da sonst Betrug relativ einfach möglich wäre. Deshalb sorgt das Mining dafür, dass im Bitcoin-Netzwerk alle Transaktionen korrekt ausgeführt werden.

Dadurch, dass alle Transaktionen an alle Teilnehmer im Netzwerk gesendet werden, können sich Nutzer an der Berechnung von sogenannten „Blockketten“ beteiligen. Wird eine Transaktion korrekt verifiziert, erhält der „Miner“, welcher aufgrund der hohen Systemanforderungen zur Lösung des Blockketten-Algorithmus meist kein einzelner Nutzer, sondern ein Pool von Nutzern (ein Bitcoin Mining Pool) ist, eine Belohnung in Form von derzeit 25 neu generierten Bitcoins. Zusätzlich kann sich der Miner etwaige Transaktionsgebühren gutschreiben, die aktuell vom Initiator der Transaktion als Anreiz zur Integration der Überweisung in den Block des Miners vergeben werden können. Wenn die direkte Belohnung für das Mining in Zukunft sinkt, werden Transaktionsgebühren im Bitcoin-System zunehmend an Bedeutung gewinnen.

Steigende Bitcoin-Anzahl und sinkende Entlohnung

Das Sinken der Entlohnung für das Mining ist systemtechnisch verankert. Dadurch werden durch das Mining über die Zeit immer weniger neue Bitcoins geschöpft, sodass sich das Geldmengenwachstum verlangsamt, bis es zum Stillstand kommt. Die begrenzte Geldmenge wird durch eine Limitierung auf insgesamt maximal 21 Millionen BTC erreicht. Derzeit befinden sich mehr als 10,5 Millionen BTC im Umlauf. Der folgende Chart zeigt das planmäßige Wachstum von Bitcoins über die Zeit. Demnach wird die maximal verfügbare Anzahl an Bitcoins voraussichtlich erst um das Jahr 2140 erreicht, wobei die extrem abflachende Wachstumskurve zeigt, dass bereits 100 Jahre vorher weit über 90% aller Bitcoins erzeugt sein werden.

Die Konsequenz des sinkenden Blockbonus ist, dass das Mining über die Zeitdauer weniger rentabel wird, zumindest für Miner mit relativ geringen Rechenkapazitäten. Langfristig werden Transaktionskosten dafür sorgen, dass das Bitcoin Mining dennoch weiterhin attraktiv bleiben wird.

Wie kann ich mich am Bitcoin-Mining beteiligen?

War es in den Anfängen von Bitcoin in den Jahren 2009 bis 2010 sogar noch möglich, als halbwegs versierter PC-Nutzer die Grafikkarte sozusagen als Bitcoin Mining Hardware zu nutzen und Blöcke zu berechnen, um neu geschöpfte Bitcoins zu erhalten, so ist dies mittlerweile praktisch unmöglich geworden. Der Ressourcenbedarf für das Bitcoin Mining ist für den durchschnittlichen PC-Nutzer viel zu hoch. Dennoch gibt es eine Möglichkeit, als Bitcoin Miner aktiv zu werden.

Dazu muss man sich zunächst einem Bitcoin Mining Pool anschließen, eine einfache google-Suche liefert bereits unzählige Pools, welche meist auch ein Forum mit nützlichen Informationen bieten. Bitcoin Mining Pools sind Netzwerke, die die gemeinsame Rechenleistung zur Berechnung von Blockketten nutzen, um neu geschöpfte BTC durch Berechnung eines Blocks zu erhalten und/oder auch von Transaktionskosten zu profitieren. Die Mining Pools unterscheiden sich nicht nur nach Größe sondern auch in der Art der Vergütung für die einzelnen Mitglieder. Gängig sind dabei unter anderem pay per share (PPS), die proportionale Verteilung unter den Mitgliedern, und die Double Geometric Method (DGM).

Bitcoin Mining: Gemeinsam zum Erfolg

Hat man sich einem Bitcoin Mining Pool angeschlossen, so hat man eine wesentlich höhere Chance, seinen Anteil an 25 neu generierten BTC zu erhalten, da der Pool aufgrund der aggregierten Rechenleistung mit hoher Wahrscheinlichkeit relativ regelmäßig einen Block erfolgreich lösen und somit als Bitcoin Miner Geld verdienen wird.

Als Bitcoin Mining Hardware dient die eigene CPU bzw. Grafikkarte, zusätzlich wird noch eine Bitcoin Mining Software benötigt, welche auf der Website des gewählten Mining Pools heruntergeladen werden kann. Das Bitcoin Mining kann häufig auch praktisch anonym erfolgen, dann wird lediglich eine Bitcoin-Adresse benötigt, so wie zum Beispiel beim Mining Pool 50BTC. Weitere verschiedene Bitcoin Mining Pools finden sich in unserem Bitcoin Verzeichnis.

Bitcoin Mining auf eigene Faust

Wer sich keinem Mining Pool anschließen, sondern sein Glück lieber auf eigene Faust versuchen möchte, muss sich die benötigte Bitcoin Mining Hardware organisieren. Ab welchen Rechenleistungen sich Bitcoin Mining lohnt, kann mit einem Bitcoin Mining Calculator berechnen. Dieser berechnet aufgrund des aktuellen Schwierigkeitsgrades, einen Block erfolgreich zu berechnen, sowie der vorhandenen Rechenleistung, wie viele BTC pro Tag oder pro Monat erwirtschaftet werden können. Bevor man sich also intensiv mit Bitcoin Mining Hardware und Software beschäftigt, lohnt sich das Berechnen der zu erwartenden Erträge mit einem Bitcoin Mining Calculator, um die benötigten Ressourcen planen zu können.

Fazit zu Bitcoin Mining: Gebündelte Ressourcen erfolgversprechend

Mit Bitcoin Mining Geld verdienen ist also kein Selbstläufer – viel mehr ist dafür neben der geeigneten Hardware auch eine Bitcoin Mining Software erforderlich. Diese kann einfach per Download bezogen werden, sofern man sich einem Bitcoin Mining Pool anschließt. Dies ist beim aktuellen Schwierigkeitsgrad der Blockberechnung auch zu empfehlen, da selbstständiges Bitcoin Mining mit sehr viel Aufwand verbunden und nicht für jeden Bitcoin Nutzer realisierbar ist.

Is Bitcoin Mining Profitable in 2018?

Last updated on February 26th, 2018 at 03:20 pm

Before we start, if you’re new to Bitcoin mining and don’t know what it is watch this short and simple explanation:

“Is Bitcoin Mining Profitable in 2018?“

The short answer would be “It depends on how much you’re willing to spend”. Each person asking himself this will get a slightly different answer since Bitcoin Mining profitability depends on many different factors. In order to find out Bitcoin mining profitability for different factors “mining profitability calculators” were invented.

These calculators take into account the different parameters such as electricity cost, the cost of your hardware and other variables and give you an estimate of your projected profit. Before I give you a short example of how this is calculated let’s make sure you are familiar with the different variables:

Bitcoin Mining terms you should get to know

Hash Rate – A Hash is the mathematical problem the miner’s computer needs to solve. The Hash Rate is the rate at which these problems are being solved. The more miners that join the Bitcoin network, the higher the network Hash Rate is.

The Hash Rate can also refer to your miner’s performance. Today Bitcoin miners (those super powerful computers talked about in the video) come with different Hash Rates. Miners’ performance is measured in MH/s (Mega hash per second), GH/s (Giga hash per second), TH/s (Terra hash per second) and even PH/s (Peta hash per second).

Bitcoins per Block – Each time a mathematical problem is solved, a constant amount of Bitcoins are created. The number of Bitcoins generated per block starts at 50 and is halved every 210,000 blocks (about four years). The current number of Bitcoins awarded per block is 12.5. The last block halving occurred on July 2016 and the next one will be in 2020.

Bitcoin Difficulty – Since the Bitcoin network is designed to produce a constant amount of Bitcoins every 10 minutes, the difficulty of solving the mathematical problems has to increase in order to adjust to the network’s Hash Rate increase. Basically this means that the more miners that join, the harder it gets to actually mine Bitcoins.

Electricity Rate – Operating a Bitcoin miner consumes a lot of electricity. You’ll need to find out your electricity rate in order to calculate profitability. This can usually be found on your monthly electricity bill.

Power consumption – Each miner consumes a different amount of energy. Make sure to find out the exact power consumption of your miner before calculating profitability. This can be found easily with a quick search on the Internet or through this list. Power consumption is measured in Watts.

Pool fees – In order to mine you’ll need to join a mining pool. A mining pool is a group of miners that join together in order to mine more effectively. The platform that brings them together is called a mining pool and it deducts some sort of a fee in order to maintain its operations. Once the pool manages to mine Bitcoins the profits are divided between the pool members depending on how much work each miner has done (i.e. their miner’s hash rate).

Time Frame – When calculating if Bitcoin mining is profitable you’ll have to define a time frame to relate to. Since the more time you mine, the more Bitcoins you’ll earn.

Profitability decline per year – This is probably the most important and elusive variable of them all. The idea is that since no one can actually predict the rate of miners joining the network no one can also predict how difficult it will be to mine in 6 weeks, 6 months or 6 years from now. This is one of the two reasons no one will ever be able to answer you once and for all “is Bitcoin mining profitable ?”. The second reason is the conversion rate. In the case below, you can insert an annual profitability decline factor that will help you estimate the growing difficulty.

Conversion rate – Since no one knows what the BTC/USD exchange rate will be in the future it’s hard to predict if Bitcoin mining will be profitable. If you’re into mining in order to accumulate Bitcoins only then this doesn’t need to bother you. But if you are planning to convert these Bitcoins in the future to any other currency this factor will have a major impact of course.

Get a mining calculator

In order to calculate all of these parameters and get an answer to our question we will use a mining profitability calculator. here’s a simple mining calculator from 99Bitcoins:

How Does Cloud Mining Bitcoin Work?

If you want to invest in bitcoin mining without the hassle of managing your own hardware, there is an alternative. You can use the cloud to earn your coins.

Put very simply, cloud mining means using (generally) shared processing power run from remote data centres. One only needs a home computer for communications, optional local bitcoin wallets and so on.

However, there are certain risks associated with cloud mining that investors need to understand prior to purchase.

Here's why you might want to consider cloud mining:

• A quiet, cooler home – no constantly humming fans
• No added electricity costs
• No equipment to sell when mining ceases to be profitable
• No ventilation problems with hot equipment
• Reduced chance of being let down by mining equipment suppliers.

Here's why you might not want to consider cloud mining:

• Risk of fraud
• Opaque mining operations
• Less fun (if you're a geek who likes system building!)
• Lower profits – the operators have to cover their costs after all
• Contractual warnings that mining operations may cease depending on the price of bitcoin
• Lack of control and flexibility.

Types of cloud mining

In general, there are three forms of remote mining available at the moment:

1. Hosted mining
   Lease a mining machine that is hosted by the provider.
2. Virtual hosted mining
   Create a (general purpose) virtual private server and install your own mining software.
3. Leased hashing power
   Lease an amount of hashing power, without having a dedicated physical or virtual computer. (This is, by far, the most popular method of cloud mining.)

How to determine profitability

We have previously covered ways to calculate mining profitability. However, the web services offered are designed to work with your hardware parameters, not cloud-mining parameters.

Even so, you can still use these calculators by thinking clearly about the costs involved. Profitability calculators (for example, The Genesis Block) often ask for your electricity costs, and sometimes the initial investment in hardware. Effectively, you are being asked for your ongoing costs and your one-off investments.

Therefore, since the provider, not you, is paying the electricity bills, you can enter the monthly mining bill in place of the electricity cost.

The conversion process isn't completely straightforward, though. In the case of hardware miners, you can work out the monthly running cost by multiplying your electricity charge (ie: $ per KWh) by the power consumption of the unit and by a conversion factor of 0.744 (the ratio of seconds per month to joules of energy per KWh).

But, for cloud mining calculations, you need to do the opposite, because the provider gives you an (effective) monthly running cost. Hence, you need to calculate an equivalent cost per kilowatt hour to feed into the mining calculator. This is done by dividing (not multiplying) the monthly running cost by the 0.744 conversion factor mentioned above.

Risk vs reward

When engaging in any type of cryptocurrency mining there are risks, but profitability is possible if you make the right choices. In this article, we've given you some pointers on how to decide which way to go.

In your test calculations, you will likely see that some cloud mining services will be profitable for a few months, but, as the difficulty level of bitcoin increases, you would probably start to make a loss in four to six months and beyond.

A possible remedy to this situation is to reinvest what you have made into maintaining a competitive hashing rate, but this is highly speculative.

As mentioned above, the risk of fraud and mismanagement is all too common in the cloud mining space. Investors should only invest in cloud mining if they are comfortable with these risks – as the saying goes, never invest more than you are willing to lose.

Investigate social media channels, speak with former customers and ask pointed questions of operators prior to investing. Ultimately, you should practice the same kind of due diligence that you would for any investment.

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

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

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.

Bitcoin Mining Calculator

Bitcoin Calculator Usage

All you need in order to make the Bitcoin Calculator display a result is to supply the speed of your mining hardware. In this simplest form the calculator will use the current Bitcoin difficulty, block value and USD/BTC rate for the calculations. However, the accuracy of the Bitcoin mining calculator improves the more honest information you supply.

Interpreting the Bitcoin Calculator Values

The mining results are based on multiple changing factors and are just valid for the given values, thus it's best practice to rely on the Bitcoin mining calculator for a short time frame only. While the Bitcoin difficulty has almost always risen after the expected validity of 14 days and thus might be somewhat forseeable, the Bitcoin exchange rate has proven to highly fluctuate, which might lead to a dramatically different outcome. Because of this dynamics we are only displaying results for at most one month.

Should I Invest in Bitcoin in 2018? Here are 4 Things You Have to Know

Last updated on January 2nd, 2018 at 12:00 am

2017 started with a bang as Bitcoin shot through the $1000 mark with no signs of slowing down. As a result I get about 2 emails a day from people around the world who are asking one very simple question: “Should I invest in Bitcoin?”

Before we begin, I want to get something out of the way – Bitcoin is not a company or a stock, it’s a currency. If you still don’t understand what Bitcoin is, watch this video. So when you want to invest in Bitcoin you are basically buying the currency. However, there are also some other forms of investing in Bitcoin.

What does it mean to invest in Bitcoin?

In order to answer this question the first thing you need to answer is what do you mean when you say you want to invest in Bitcoin. Do you want to buy the currency in hopes it will appreciate it value? Do you want to invest in Bitcoin related companies? Are you looking to day trade with Bitcoins?

Buying and holding

The most common form of “investing” in Bitcoin is buying the currency in hopes it will appreciate in value (also knowns as “hodling”, see the origins of the term here). If this is the case then you need to decide for yourself if you think this is a good time to buy. Meaning, do you think the price will continue to rise.

Don’t take anyone’s advice about what will happen with the currency, do your homework, learn about Bitcoin and come to a conclusion. Personally I believe we are just starting, but that’s my own opinion and you shouldn’t consider that as investment advice as well.

A few pointers for buying and holding Bitcoins:

1. Never invest more than you are willing/able to lose – Bitcoin is a very risky investment and you should keep in that in mind at all times.
2. After buying Bitcoins make sure to move them into your own personal wallet and never leave them at the exchange. My personal recommendation is to use a hardware wallet to store your Bitcoins. If you can’t afford a hardware wallet, try a paper wallet.
3. Make sure to buy Bitcoins only from exchanges that have proven their reputation.
4. Buy Bitcoins through Dollar cost averaging – This means that you don’t buy all of your Bitcoins in one trade but instead buy a fixed amount every month, week or even day throughout the year. This way you average the price over the course of a whole year. Here’s a short video to explain this concept:

Trading in Bitcoins

Bitcoin trading is different than buying and holding. When you are trading Bitcoins it means that you are actively trying to buy Bitcoins at a low price and sell them back at a higher price in relatively short time interval. Trading successfully requires knowledge and practice. The trading market is occupied by very large players who are just waiting for newbies to come in and throw their money away by trading aimlessly.

If you want to learn more about Bitcoin trading here are some practical tips to help you out.

Investing in Bitcoin mining

Some people would like to invest their money into mining Bitcoin. For the past few years mining Bitcoin is only profitable if done at large scales. This means you will need to get expensive mining equipment and hopefully have access to free electricity. Also it’s usually much more cost effective to buy Bitcoins with this money instead of using it to buy mining equipment.

Some of you may have heard of all sorts of sites that allow you to mine Bitcoins through them. This is known as cloud mining and these sites fall into one out of two categories:

1. They are complete scams that will run away with your money and don’t actually use it to mine Bitcoin.
2. They are not scams, but they are bad investments since you will probably get more Bitcoins if you just use that money to buy Bitcoins instead of paying the site.

Invest in Bitcoin companies / grow your Bitcoins / HYIPs

Finally, every other day I get a question about a site or company that claims to double your Bitcoins, give you insane daily interest on your Bitcoins or help you invest them in some sort of complex and obscure scheme. These sites can be categorized mostly as scams or HYIPs (high yield investment programs).

What these sites usually do is they take money from people around the web and promise to give them good returns. They will then start off by paying these returns through money they get from new sign ups and create a big buzz around the site. Usually they will also have some sort of referral program so that users can bring in their friends. This will go on for around 3-4 months until one day the website will just go offline and the money will be gone. No more payments will be made and a lot of people will get mad that they got scammed.

I have reviewed many Bitcoin investment sites in the past 3 years (e.g. BTCJam, Bitcoin Trader) and I have yet to find a site that I can say is legit or safe to invest in. Any site that promises you something that is too good to be true is probably just a facade for scammers trying to steal your coins.

How can you find out if a site is a scam for yourself? Easy, use our Bitcoin scam test tool. I can’t emphasis this enough – STAY AWAY FROM SITES THAT CLAIM THEY WILL DOUBLE YOUR COINS OR GIVE YOU DAILY INTEREST ON THEM.

So should you invest in Bitcoin?

By now you can probably see that the answer isn’t that simple. It’s not just a matter of should you invest, but also a matter of how to invest. Like I said in the beginning, start by educating yourself. Learn about the currency, what affects it, what are its advantages and disadvantages, etc. You can get a lot of basic education through our free Bitcoin crash course (sign up at the bottom of this post).

After you feel you’ve acquired some basic education it’s time to answer this question. REMEMBER – only you can answer this. You can consult others and read online but never follow someone’s advice blindly.

Bitcoin: Lohnt sich das Mining noch?

Lohnt sich das Hobby Bitcoin-Mining bei steigender Schwierigkeit und fallenden bzw. stagnierenden Bitcoin Preisen noch? Manche Experten sagen Ja. Ravy Iyengar, Gründer und CEO von Cointerra sagt sein mittlerweile insolventes Unternehmen sei es gewohnt gewesen, genauso viele ASIC Miner an Privatleute und Investoren wie auch an industrielle Mining-Unternehmen zu verkaufen.

„Das Verhältnis sei jedoch kleiner geworden,“ so Iyengar. Zuletzt gingen ungefähr 20% der Miner an Privatleute bzw. Hobby-Miner. Ein Rückgang sei auch noch heute zu beobachten. Gründe dafür sind die sinkenden Bitcoin Preise und die steigende Mining-Schwierigkeit.

Hohe Energiekosten

Es gibt viele Faktoren die sich auf die Rentabilität das Bitcoin-Mining auswirken. Auf der einen Seite gibt es die Anschaffungs,- bzw. Hardwarekosten und auf der anderen Seite die Energiekosten. Der aktuelle Bitcoin Preis spielt natürlich auch eine Schlüsselrolle.

„Zu diesem Zeitpunkt sieht es so aus als würde sich das Hobby Mining von zu Hause aus nicht lohnen, da Privatleute nicht an den günstigen Strom herankommen, wie z.B. die industriellen Miner in diversen Low Cost Areas.“

2013 lagen die durschnittlichen Einzelhandelsstromkosten in den USA bei 10 Cent pro kWh (Quelle: US Chamber of Commerce Insitute for 21st Century Energy). Bei der derzeitigen Schwierigkeit und dem derzeitigen Bitcoin Preis würde das bedeuten es dauert mehr als vier Jahre um mit einen gebrauchten 1.6 TH/sek TerraMiner den Break-Even zu erreichen.

In Massachusetts, wo der Strompreis bei ca. 14,5 Cent pro kWh liegt wird der Break-Even bei dem derzeitigen BTC Preis nie erreicht. Natürlich ändert sich den Rentabilität abhängig vom Bitcoin Preis aber die Stromkosten fallen bei den Enrgieschleudern sehr ins Gewicht und ein Unterschied von nur einem Cent pro kWh kann entscheidend sein.

Es kommen sicherlich immer effizientere Miner auf den Markt, aber der Privatverbraucher wird immer hinterherlaufen, weil er viel Geld für einen Miner ausgibt, der meist viel zu spät geliefert wird und das in einem Business wo bei der steigenden Schwierigkeit wirklich jeder Tag zählt, so Adam McKenna vom Mining Pool Multipool.

„An dem Tag wo der Miner letztendlich bei dem Hobbyminer zu Hause angelangt ist, ist die Schwierigkeit wahrscheinlich schon um 20-30% gestiegen.“

Vorteiles des industriellen Bitcoin-Mining

Industrielle Miner haben es da einfacher, denn sie haben Zugriff auf den billigen Strom.

„Die Stromkosten pro kWh für einen Privathaushalt sind viel höher als die eines Rechencenters,“ so Emmanuel Abidun Vorsitzender von PeerNova. PeerNova verkauft eigenen Miner und bietet aber auch die Möglichkeit von CloudHashing bei dem Privatleute Mining-Anteile kaufen können.

Der durchschnittliche Strompreis für Industriekunden lag laut 451 Research bei 7 Cent pro kWh in den USA. Die Rechenzentren haben dann noch den Vorteil, dass sie sich in Regionen niederlassen können, wo der Strom noch günstiger ist.
Zudem haben die Rechenzentren einen Vorteil wenn es zur Gewährleistung des Mining-Equipments kommt, so McKenna:

„Das größte Problem der Hobbyminer ist das Lieferdatum. Cloud Mining Unternehmen bestellen in großen Mengen und können somit ein Lieferdatum aushandeln was weit vor denjenigen liegt, die nur einen oder zwei Miner bestellen.“

Weiter Vorteile der großen CloudMiner ist die gewährleistete Stromversorgung, da die Miner oftmals Starkstrom benötigen und der Vorteil, dass Sie wie z.B. CloudHashing ihre ASIC Chips mittlerweile selbst herstellen können.

Bitcoin Preisschwankungen

Bei dem derzeit niedrigen Bitcoin Preis ist es kein Wunder, dass die Mining-Rentabilität zu wünschen übrig lässt. Sollte der Preis jedoch bei der heutigen Schwierigkeit wieder auf 1.000 US-Dollar springen würde die Welt schon wieder ganz anders aussehen.

Sollten Hobbyminer also fleißig weiter minen, in der Hoffnung dass der Bitcoin Kurs bald wieder steigt?

„Wenn du ein kleiner Hobbyminer bist und darauf hoffst, dass der Preis bald wieder steigt, dann solltest du lieber BTC kaufen,“ so Iyengar.

Wenn du Bitcoin Mining betreibst weil du überzeugt davon bist, dass der Preis steigen wird, dann bedeutet eine 300 Euro Investition in Bitcoin eine Investition in eine fixe Schwierigkeit und einen fixen BTC Preis. Dann lässt du ab sofort den Markt für dich arbeiten. Solltest du das Geld jedoch lieber in Mining-Equipment investieren, investierst du langfristig in Bitcoin und kämpfst in der Zwischenzeit gegen die steigende Schwierigkeit.

Comparison of mining pools

Reward types & explanation:

• CPPSRB - Capped Pay Per Share with Recent Backpay. [1]
• DGM - Double Geometric Method. A hybrid between PPLNS and Geometric reward types that enables to operator to absorb some of the variance risk. Operator receives portion of payout on short rounds and returns it on longer rounds to normalize payments. [2]
• ESMPPS - Equalized Shared Maximum Pay Per Share. Like SMPPS, but equalizes payments fairly among all those who are owed. [3]
• POT - Pay On Target. A high variance PPS variant that pays on the difficulty of work returned to pool rather than the difficulty of work served by pool [4]
• PPLNS - Pay Per Last N Shares. Similar to proportional, but instead of looking at the number of shares in the round, instead looks at the last N shares, regardless of round boundaries.
• PPLNSG - Pay Per Last N Groups (or shifts). Similar to PPLNS, but shares are grouped into "shifts" which are paid as a whole.
• PPS - Pay Per Share. Each submitted share is worth certain amount of BTC. Since finding a block requires shares on average, a PPS method with 0% fee would be 12.5 BTC divided by . It is risky for pool operators, hence the fee is highest.
• Prop. - Proportional. When block is found, the reward is distributed among all workers proportionally to how much shares each of them has found.
• RSMPPS - Recent Shared Maximum Pay Per Share. Like SMPPS, but system aims to prioritize the most recent miners first. [5]
• Score - Score based system: a proportional reward, but weighed by time submitted. Each submitted share is worth more in the function of time t since start of current round. For each share score is updated by: score += exp(t/C). This makes later shares worth much more than earlier shares, thus the miner's score quickly diminishes when they stop mining on the pool. Rewards are calculated proportionally to scores (and not to shares). (at slush's pool C=300 seconds, and every hour scores are normalized)
• SMPPS - Shared Maximum Pay Per Share. Like Pay Per Share, but never pays more than the pool earns. [6]
• FPPS - Full Pay Per Share. Similar to PPS，but not only divide regular block reward (12.5 BTC for now) but also some of the transaction fees. Calculate a standard transaction fee within a certain period and distribute it to miners according to their hash power contributions in the pool. It will increase the miners' earnings by sharing some of the transaction fees.
