Bitcoin Mining Profit Calculator

Why Our Calculator is the Most Accurate

There are many factors that affect your mining profitability. Two of the main factors that influence your profitability are: the Bitcoin price and the total network hash rate.

The Bitcoin network hash rate is growing at a rate of 0.4527678% per day. This means if you buy 50 TH/s of mining hardware your total share of the network will go DOWN every day compared to the total network hash rate.

Our calculator assumes the 0.4527678% daily increase in network hash rate that has been the average daily increase over the past 6 months.

Without factoring in this growth, most Bitcoin mining calculators show results that appear MUCH, MUCH more profitable than reality.

The Bitcoin Price

Even though the network hash rate will cause your share of the network hash power to go down, the Bitcoin price can help make up some of these losses.

The Bitcoin price is rising at a slightly lesser 0.3403% per day over the past year. We suggest you enter a custom Bitcoin price into our calculator based on what you expect the average price to be over the next year.

What our Calculator Assumes

Since our calculator only projects one year out, we assume the block reward to be 12.5. We also use the current Bitcoin price in our calculations, but you can change the Bitcoin price to anything you'd like to get better data.

Welcome to 99Bitcoins’ simple Bitcoin Mining Calculator

This simple Bitcoin mining calculator will allow you to determine how much you can profit from a certain Bitcoin miner. It takes into account all relevant costs such as hardware, electricity and fees. See below for detailed instructions on how to use it.

Instructions on how to use the Bitcoin Mining Calculator:

1. Enter the hash rate of the Bitcoin miner you’re planning to use
2. Click on “Calculate mining revenue”
3. That’s it! (we said it was simple….)

Note: If some values in the Bitcoin mining calculator don’t seem right (exchange rate, block reward, etc.) you can adjust them manually. However normally they are all up to date.

Keep in mind that:

• Revenue is shown in USD based on the current exchange rate, the exchange rate can (and probably will) change from time to time.
• Revenue is based on current difficulty to mine Bitcoins. Difficulty can (and probably will) change. From past experience it usually goes up as time goes by.
• Revenue IS NOT profit. You still have to take into account the cost of your mining hardware and the electricity to run it (and cool it down if needed).

How to Calculate Bitcoin Mining Profitability

Bitcoin mining secures the Bitcoin network. Without miners, Bitcoin could easily be attacked and even shut down. Since Bitcoin miners provide such an important service to the network, they are paid for their services! Each block mined by miners contains a block reward, which is paid out to the miner that successfully mined the block.

While mining today is very competitive, it is possible to run a successful and profitable mining farm. This post will outline the many factors that will determine whether or not your mining operation will be profitable.

Mining Hardware Costs

The upfront costs to pay for mining hardware is usually the largest expense for any new mining farm. Just like good computers cost more money, good mining hardware is expensive. The Antminer S7 is one currently the most efficient miner and costs $629. It only mines about $200 worth of bitcoins per month, meaning just based on hardware costs alone it will take more than three months to get back your money. This does not include electricity costs or equipment costs (more on this below).

When purchasing mining hardware, you will want to look at these metrics: Th/s and W/GH. Th/s, or sometimes Gh/s, measures a miner’s terahashes (Th/s) or gigahashes (Gh/s) per second and is called hash rate. A higher hash rate means a more powerful miner. You can use this simple calculator from Bitcoin Wisdom to determine how much money an amount of hash power will earn per month.

Hardware Efficiency

Hash power is not the end all for determining good miners, though. Miners use massive amounts of electricity. You want a miner that has both a high hash rate and uses the electricity provided efficiently.

W/GH is the metric used to display a miner’s efficiency. The Antminer S7 is also the most efficient miner available on the market, with 0.25 W/GH. Consider that the previous version of the S7, the S5, had an efficiency of just 0.51 W/GH. That means the S5 uses twice as much electricity per hash as the S7.

Buying a miner that has a low W/GH and also has good hash power is the key for any profitable mining operation.

Equipment Costs

Miners generate heat, and also need to be supplied with electricity. Unless you already have the needed parts, you will likely need to purchase cooling fans and power supplies.

Electricity Costs

Electricity costs can make or break any mining operation. A monthly electric bill means monthly costs on top of the upfront cost of the hardware.

China’s cheap electricity is one reason that nearly 60% of the Bitcoin network’s hashing power is located there. In the USA, for example, most mining hardware is run in Washington State, where there is cheap hydroelectricity. Venezuela’s crisis and cheap electricity has also made Bitcoin mining extremely profitable there.

Don’t discount electricity as a cost. It can make or break your mining operation.

Extra Heat and Weather

Creative miners in cold areas can use the heat generated by miners to heat their houses in the winter. If the heat generated by miners will partly replace your normal heating costs, it is one way to save money and improve your chances of profitability.

Miners in cold areas also have an advantage because they may not need to use extra fans to cool the hardware.

Bitcoin Mining Difficulty and Network Hash Power

The Bitcoin mining difficulty makes sure that Bitcoin blocks are mined, on average, every 10 minutes. A higher difficulty is indicative of more hash power joining the network.

As you would expect, more hash power on the network means that existing miners then control a lower percentage of the Bitcoin network hash power.

The image above shows the network hash power over the last 2 years. From September 2015 to February 2016, the network hash rate tripled. That means any miner who added no additional hardware to his farm would earn about 33% less bitcoins.

Hash rate and network difficulty are external factors that should be accounted for. It’s impossible to know difficulty months in advance. However, pay attention to advances in mining technology and efficiency to get a better idea of how the hash rate and difficulty may look down the line.

Bitcoin Price and Block Reward

Bitcoin’s price is volatile and can’t be predicted. You may calculate your profitability with a Bitcoin price of $500, but it won’t be accurate if the price drops to $300 the next day. Be prepared for price movements and understand that the Bitcoin price is a factor that you cannot control.

The Bitcoin block reward is at least one factor that is predictable. Every 4 years, the amount of bitcoins rewarded in each block is cut in half. The reward started at 50 bitcoins per block, and is now 25 bitcoins per block. In July 2016, this reward will fall to just 12.5 bitcoins per block.

Each block reward halving cuts miners’ shares of bitcoins in half. Miners can, however, see similar incomes after a reward halving if the fiat price of Bitcoin doubles.

Bitcoin Mining Calculators

To conclude, use a Bitcoin mining calculator to input your hardware information and electricity costs. This will give you a much better idea on your overall potential to run a profitable mining farm. Remember, however, that some factors like the Bitcoin price and mining difficulty change everyday and can have dramatic effects on profitability.

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

Before we begin.

Before you read further, please understand that most bitcoin users don't mine! But if you do then this Bitcoin miner is probably the best deal. Bitcoin mining for profit is very competitive and volatility in the Bitcoin price makes it difficult to realize monetary gains without also speculating on the price. Mining makes sense if you plan to do it for fun, to learn or to support the security of Bitcoin and do not care if you make a profit. If you have access to large amounts of cheap electricity and the ability to manage a large installation and business, you can mine for a profit.

If you want to get bitcoins based on a fixed amount of mining power, but you don't want to run the actual hardware yourself, you can purchase a mining contract.

Another tool many people like to buy is a Bitcoin debit card which enables people to load a debit card with funds via bitcoins.

What is Bitcoin mining?

Bitcoin mining is a lot like a giant lottery where you compete with your mining hardware with everyone on the network to earn bitcoins. Faster Bitcoin mining hardware is able to attempt more tries per second to win this lottery while the Bitcoin network itself adjusts roughly every two weeks to keep the rate of finding a winning block hash to every ten minutes. In the big picture, Bitcoin mining secures transactions that are recorded in Bitcon's public ledger, the block chain. By conducting a random lottery where electricity and specialized equipment are the price of admission, the cost to disrupt the Bitcoin network scales with the amount of hashing power that is being spent by all mining participants.

Technical Background

During mining, your Bitcoin mining hardware runs a cryptographic hashing function (two rounds of SHA256) on what is called a block header. For each new hash that is tried, the mining software will use a different number as the random element of the block header, this number is called the nonce. Depending on the nonce and what else is in the block the hashing function will yield a hash which looks something like this:

You can look at this hash as a really long number. (It's a hexadecimal number, meaning the letters A-F are the digits 10-15.) To ensure that blocks are found roughly every ten minutes, there is what's called a difficulty target. To create a valid block your miner has to find a hash that is below the difficulty target. So if for example the difficulty target is

any number that starts with a zero would be below the target, e.g.:

If we lower the target to

we now need two zeros in the beginning to be under it:

Because the target is such an unwieldy number with tons of digits, people generally use a simpler number to express the current target. This number is called the mining difficulty. The mining difficulty expresses how much harder the current block is to generate compared to the first block. So a difficulty of 70000 means to generate the current block you have to do 70000 times more work than Satoshi Nakamoto had to do generating the first block. To be fair, back then mining hardware and algorithms were a lot slower and less optimized.

To keep blocks coming roughly every 10 minutes, the difficulty is adjusted using a shared formula every 2016 blocks. The network tries to change it such that 2016 blocks at the current global network processing power take about 14 days. That's why, when the network power rises, the difficulty rises as well.

Bitcoin Mining Hardware

In the beginning, mining with a CPU was the only way to mine bitcoins and was done using the original Satoshi client. In the quest to further secure the network and earn more bitcoins, miners innovated on many fronts and for years now, CPU mining has been relatively futile. You might mine for decades using your laptop without earning a single coin.

About a year and a half after the network started, it was discovered that high end graphics cards were much more efficient at bitcoin mining and the landscape changed. CPU bitcoin mining gave way to the GPU (Graphical Processing Unit). The massively parallel nature of some GPUs allowed for a 50x to 100x increase in bitcoin mining power while using far less power per unit of work.

While any modern GPU can be used to mine, the AMD line of GPU architecture turned out to be far superior to the nVidia architecture for mining bitcoins and the ATI Radeon HD 5870 turned out to be the most cost effective choice at the time.

As with the CPU to GPU transition, the bitcoin mining world progressed up the technology food chain to the Field Programmable Gate Array. With the successful launch of the Butterfly Labs FPGA 'Single', the bitcoin mining hardware landscape gave way to specially manufactured hardware dedicated to mining bitcoins.

While the FPGAs didn't enjoy a 50x - 100x increase in mining speed as was seen with the transition from CPUs to GPUs, they provided a benefit through power efficiency and ease of use. A typical 600 MH/s graphics card consumed upwards of 400w of power, whereas a typical FPGA mining device would provide a hashrate of 826 MH/s at 80w of power.

That 5x improvement allowed the first large bitcoin mining farms to be constructed at an operational profit. The bitcoin mining industry was born.

The bitcoin mining world is now solidly in the Application Specific Integrated Circuit (ASIC) era. An ASIC is a chip designed specifically to do one thing and one thing only. Unlike FPGAs, an ASIC cannot be repurposed to perform other tasks.

An ASIC designed to mine bitcoins can only mine bitcoins and will only ever mine bitcoins. The inflexibility of an ASIC is offset by the fact that it offers a 100x increase in hashing power while reducing power consumption compared to all the previous technologies.

Unlike all the previous generations of hardware preceding ASIC, ASIC may be the "end of the line" when it comes to disruptive mining technology. CPUs were replaced by GPUs which were in turn replaced by FPGAs which were replaced by ASICs. There is nothing to replace ASICs now or even in the immediate future.

There will be stepwise refinement of the ASIC products and increases in efficiency, but nothing will offer the 50x to 100x increase in hashing power or 7x reduction in power usage that moves from previous technologies offered. This makes power consumption on an ASIC device the single most important factor of any ASIC product, as the expected useful lifetime of an ASIC mining device is longer than the entire history of bitcoin mining.

It is conceivable that an ASIC device purchased today would still be mining in two years if the device is power efficient enough and the cost of electricity does not exceed it's output. Mining profitability is also dictated by the exchange rate, but under all circumstances the more power efficient the mining device, the more profitable it is. If you want to try your luck at bitcoin mining then this Bitcoin miner is probably the best deal.

Bitcoin Mining Software

There are two basic ways to mine: On your own or as part of a Bitcoin mining pool or with Bitcoin cloud mining contracts and be sure to avoid Bitcoin cloud mining scams. Almost all miners choose to mine in a pool because it smooths out the luck inherent in the Bitcoin mining process. Before you join a pool, make sure you have a bitcoin wallet so you have a place to store your bitcoins. Next you will need to join a mining pool and set your miner(s) to connect to that pool. With pool mining, the profit from each block any pool member generates is divided up among the members of the pool according to the amount of hashes they contributed.

How much bandwidth does Bitcoin mining take? If you are using a bitcoin miner for mining with a pool then the amount should be negligible with about 10MB/day. However, what you do need is exceptional connectivity so that you get any updates on the work as fast as possible.

This gives the pool members a more frequent, steady payout (this is called reducing your variance), but your payout(s) can be decreased by whatever fee the pool might charge. Solo mining will give you large, infrequent payouts and pooled mining will give you small, frequent payouts, but both add up to the same amount if you're using a zero fee pool in the long-term.

Bitcoin Cloud Mining

By purchasing Bitcoin cloud mining contracts, investors can earn Bitcoins without dealing with the hassles of mining hardware, software, electricity, bandwidth or other offline issues.

Being listed in this section is NOT an endorsement of these services and is to serve merely as a Bitcoin cloud mining comparison. There have been a tremendous amount of Bitcoin cloud mining scams.

Hashflare Review: Hashflare offers SHA-256 mining contracts and more profitable SHA-256 coins can be mined while automatic payouts are still in BTC. Customers must purchase at least 10 GH/s.

Genesis Mining Review: Genesis Mining is the largest Bitcoin and scrypt cloud mining provider. Genesis Mining offers three Bitcoin cloud mining plans that are reasonably priced. Zcash mining contracts are also available.

Hashing 24 Review: Hashing24 has been involved with Bitcoin mining since 2012. They have facilities in Iceland and Georgia. They use modern ASIC chips from BitFury deliver the maximum performance and efficiency possible.

What is Bitcoin Mining?

Bitcoin mining is the process of adding transaction records to Bitcoin's public ledger of past transactions. This ledger of past transactions is called the block chain as it is a chain of blocks. The block chain serves to confirm transactions to the rest of the network as having taken place.

Bitcoin nodes use the block chain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.

Bitcoin mining is intentionally designed to be resource-intensive and difficult so that the number of blocks found each day by miners remains steady. Individual blocks must contain a proof of work to be considered valid. This proof of work is verified by other Bitcoin nodes each time they receive a block. Bitcoin uses the hashcash proof-of-work function.

The primary purpose of mining is to allow Bitcoin nodes to reach a secure, tamper-resistant consensus. Mining is also the mechanism used to introduce Bitcoins into the system: Miners are paid any transaction fees as well as a "subsidy" of newly created coins.

This both serves the purpose of disseminating new coins in a decentralized manner as well as motivating people to provide security for the system.

Bitcoin mining is so called because it resembles the mining of other commodities: it requires exertion and it slowly makes new currency available at a rate that resembles the rate at which commodities like gold are mined from the ground.

What is Proof of Work?

A proof of work is a piece of data which was difficult (costly, time-consuming) to produce so as to satisfy certain requirements. It must be trivial to check whether data satisfies said requirements.

Producing a proof of work can be a random process with low probability, so that a lot of trial and error is required on average before a valid proof of work is generated. Bitcoin uses the Hashcash proof of work.

What is Bitcoin Mining Difficulty?

The Computationally-Difficult Problem

Bitcoin mining a block is difficult because the SHA-256 hash of a block's header must be lower than or equal to the target in order for the block to be accepted by the network.

This problem can be simplified for explanation purposes: The hash of a block must start with a certain number of zeros. The probability of calculating a hash that starts with many zeros is very low, therefore many attempts must be made. In order to generate a new hash each round, a nonce is incremented. See Proof of work for more information.

The Bitcoin Network Difficulty Metric

The Bitcoin mining network difficulty is the measure of how difficult it is to find a new block compared to the easiest it can ever be. It is recalculated every 2016 blocks to a value such that the previous 2016 blocks would have been generated in exactly two weeks had everyone been mining at this difficulty. This will yield, on average, one block every ten minutes.

As more miners join, the rate of block creation will go up. As the rate of block generation goes up, the difficulty rises to compensate which will push the rate of block creation back down. Any blocks released by malicious miners that do not meet the required difficulty target will simply be rejected by everyone on the network and thus will be worthless.

The Block Reward

When a block is discovered, the discoverer may award themselves a certain number of bitcoins, which is agreed-upon by everyone in the network. Currently this bounty is 25 bitcoins; this value will halve every 210,000 blocks. See Controlled Currency Supply or use a bitcoin mining calculator.

Additionally, the miner is awarded the fees paid by users sending transactions. The fee is an incentive for the miner to include the transaction in their block. In the future, as the number of new bitcoins miners are allowed to create in each block dwindles, the fees will make up a much more important percentage of mining income.

Was ist Bitcoin-Mining?

Bevor wir beginnen.

Bevor Sie weiterlesen, machen Sie sich bitte bewusst, dass die meisten Bitcoin-Benutzer nicht schürfen! Wenn Sie aber schürfen, dürfte diesesBitcoin-Schürfgerät die beste Wahl sein.Beim kommerziellenMining (deutsch‚Schürfen‘) von Bitcoins herrscht starker Wettbewerb. Zudem macht es der schwankungsanfällige Bitcoin-Preisschwierig, finanzielle Gewinne zu erzielen, ohne auch auf den Preis zu spekulieren.Das Schürfen macht auch dann Sinn, wenn man sich nicht um Gewinne schert, es zum Spaß betreibt und lernen oder zur Sicherheit von Bitcoin beitragen will. Sofern große Mengen an billiger Elektrizität verfügbar sind und eine große kommerzielle Anlage verwaltet werden kann, wirft das Schürfen Gewinne ab.

Wer Bitcoins als Gegenleistung für eine festgelegte Rechenleistung bekommen möchte, die Hardware aber nicht selbst betreiben will, kann einen Schürfvertrag abschließen. Ein weiteres Hilfsmittel, das gern gekauft wird, ist die Bitcoin-Debitkarte, die man im Austausch gegen Bitcoins mit Geld aufladen kann.

Was ist Bitcoin-Mining?

Das Bitcoin-Mining, das Schürfen von Bitcoins,ähneltstark einer riesigen Lotterie, bei der man mit seiner Schürf-Hardware mit allenanderen Leuten im Netzwerk konkurriert, um Bitcoins zu verdienen.Je schneller die Schürf-Hardware ist, desto mehr Versuche sind pro Sekunde möglich, diese Lotterie zu gewinnen.Unterdessen passt sich das Bitcoin-Netzwerk etwa alle zwei Wochen so an, dass die für dasErmitteln eines Gewinner-Blockhashs benötigte Zeit konstant bei zehn Minuten bleibt. Allgemein ausgedrückt: Das Schürfen von Bitcoins sorgt für die Sicherheit von Transaktionen, die in der öffentlichen Bitcoin-Datenbank, der Blockchain, verzeichnet werden.Der Preis für die Teilnahme an dieser Glückslotterie sind Elektrizität und eine spezielles Ausrüstung. Damit steigen die Kosten, um das Bitcoin-Netzwerk zu stören, parallel zu der gesamten Rechenleistung, die von allen Schürfernaufgewendet wird.

Technische Hintergründe

Beim Schürfen wendet die Hardware zweimal die kryptologische Hashfunktion SHA256) auf den sogenannten Blockheader an. Die Schürf-Software verwendet bei jedem neuen Versuch, einen passenden Hash zu erzeugen, eine andere Zahl als zufälligen Bestandteil für den Blockheader. Diese Zahl wird Noncegenannt. Je nachdem, wie die Nonce lautet und was sich sonst noch in dem Block befindet, liefert die Hashfunktion einen Hash, der ungefähr so aussieht:

Man kann diesen Hash als eine extrem lange Zahl sehen, genauer gesagt eine Hexadezimalzahl, bei der die Buchstaben A–F den Zahlen 10–15 entsprechen. Um zu gewährleisten, dass etwa alle zehn Minuten ein Block gefunden wird, gibt es die sogenannte Ziel-Schwierigkeit. Die Schürf-Software muss, um einen gültigen Block zu erzeugen, einen Hash finden, der unter der Ziel-Schwierigkeit liegt. So läge bei einer Ziel-Schwierigkeit von

jede Zahl, die kleiner als 0 ist, unterhalb der Ziel-Schwierigkeit, z. B.

Durch Herabsetzen der Ziel-Schwierigkeit auf

sind zwei Nullen am Anfang nötig, damit der Hash darunter liegt:

Da das Ziel eine solch sperrige Zahl mit einer Unmenge von Stellen ist, verwenden die Schürfer meist eine einfachere Zahl, um das aktuelle Ziel auszudrücken.Diese Zahl ist die sogenannte Schürf- oder Mining-Schwierigkeit. Der Schwierigkeitsgrad drückt aus, um wie viel schwieriger das Erzeugen des aktuellen Blocks im Vergleich zum Erzeugen des ersten jemals erzeugten Blocks ist. Ein Schwierigkeitsgrad von 70.000 bedeutet demnach: Die für den aktuellen Block erforderliche Rechenleistung ist 70.000-mal höher als die Rechenleistung, die Satoshi Nakamoto brauchte, um den allerersten Block zu erzeugen. Der Fairness halber muss gesagt werden, dass die damalige Schürf-Software und die Algorithmen viel langsamer und weniger optimiert waren.

Damit kontinuierlich etwa alle zehn Minuten ein Block entsteht, wird der Schwierigkeitsgrad nach jeweils 2016 Blöcken mithilfe einer freigegebenen Formelangepasst. Das Netzwerk versucht den Schwierigkeitsgrad so zu verändern, dass es ungefähr 14 Tage dauert, um mit der aktuellen globalen Rechenleistung2016 Blöcke zu erzeugen. Das ist der Grund, warum mitzunehmender Netzwerk-Rechenleistung auch der Schwierigkeitsgrad steigt.

Bitcoin-Schürf-Hardware

CPU

Anfangs war das Schürfen per CPUund mithilfe des Original-Clients von Satoshi der einzige Weg, um Bitcoins zu erzeugen.Auf der Suche nach Möglichkeiten, das Netzwerk sicherer zu machen und mehr Bitcoins zu gewinnen, haben die Schürfer zahlreiche Innovationen entwickelt; mittlerweile ist das Schürfen per CPU seit Jahren relativ sinnlos. Mit dem Laptop schürft man möglicherweise jahrzehntelang, ohne einen einzigen Bitcoin zu verdienen.

GPU

Etwa anderthalb Jahre nach der Gründung des Netzwerks fand man heraus, dass sich mithilfe von High-End-Grafikkarten die Bitcoins viel effizienter schürfen ließen. Eine neue Situation war entstanden. Das CPU-basierte Schürfen wich dem Schürfen per GPU (Grafikprozessor, englisch graphics processing unit). Da einige Grafikprozessoren in der Lage waren, enorme Aufgabenmengen parallel auszuführen, ergab sicheine 50- bis 100-mal höhere Schürfleistung bei gleichzeitig weitausgeringerem Energieverbrauch pro Leistungseinheit.

Obwohl jeder moderne Grafikprozessor zum Schürfen verwendet werden kann, hat sich die Prozessorarchitekturvon AMD-Grafikkarten im Vergleich zur Architektur von nVidia-Grafikkarten als deutlich überlegen erwiesen. Die derzeit kosteneffizienteste Variante ist die ATI Radeon HD 5870.

FPGA

Wie schon beim Übergang vom CPU- zum GPU-basierten Schürfen stieg das Bitcoin-Schürfen dank Field Programmable Gate Array (FPGA) in der technologischen Nahrungskette weiter auf.Der erfolgreiche Start von Butterfly Labs FPGA Single machte den Weg frei für Hardware, die speziell für das Schürfen von Bitcoins ausgelegt ist.

Zwar brachten die FPGAs keine 50- bis 100-fache Erhöhung der Schürfgeschwindigkeit, wie es beim Übergang von CPU zu GPU der Fall gewesen war, doch dafür hatten FPGAs den Vorzug, energieeffizient und benutzerfreundlich zu sein. Während eine klassische Grafikkarte bei einer Leistung von 600 Mhash/s bis zu 400 Watt Strom verbrauchte, lieferte ein typisches FPGA-Schürfgerät eine Hashrate von 826 MHash/s – bei einem Verbrauch von 80 Watt.

Der fünfmal niedrigere Energieverbrauch machte es möglich, die ersten großen Bitcoin-Schürfparks, die operative Gewinne versprachen, zu bauen. Die Bitcoin-Schürfindustrie war geboren.

ASIC

Heute ist die Welt des Bitcoin-Schürfens längst im Zeitalter des Application Specific Integrated Circuit (ASIC, deutsch anwendungsspezifische integrierte Schaltung) angekommen. Ein ASIC ist ein Chip, der speziell für einen einzigen Zweck entwickelt wird.Anders als FPGAs lassen sich ASICsnicht für das Ausführen anderer Aufgaben umfunktionieren.

Ein ASIC, der für das Schürfen von Bitcoins entwickelt wurde, kann und wird nichts anderes tun als Bitcoins schürfen.Die fehlende Flexibilität des ASIC wird durch die Tatsache wettgemacht, dass er im Vergleich zu sämtlichen älteren Technologien 100-mal mehr Hashing-Leistung bietet und dabei auch noch weniger Strom verbraucht.

Anders als bei früheren Hardware-Entwicklungen könnte mit ASIC, was bahnbrechende Schürftechnologien betrifft, gewissermaßen das Ende der Fahnenstange erreicht sein. CPUs wurden abgelöst von GPUs, an deren Stelle FPGAs traten, die dannihrerseits durch ASICs verdrängt wurden.Es gibt weder jetzt noch in unmittelbarer Zukunft eine Technologie, die als Ersatz für ASICsgeeignet wäre.

Schrittweise Verbesserungen bei den ASICs-Produkten wird es zwargeben unddie Effizienz wird sich weiter erhöhen, doch die Zeiten, wo neue Technologien eine 50- bis 100-fache Steigerung der Hashing-Leistungbrachten, sind vorüber.So wird der Stromverbrauch von ASIC-Geräten zum wichtigsten aller Faktoren: Die zu erwartende Gebrauchsdauer eines beliebigen ASIC-Schürfgeräts istnämlich länger als die Geschichte des Bitcoin-Schürfens selbst.

Es darf angenommen werden, dass ein heute gekauftes ASIC-Gerät noch in zwei Jahren schürft, wenn das Gerät hinreichend energieeffizient ist und die Stromkosten nicht höher als die Ausbeute sind. Die Rentabilität des Schürfens hängt auch vom Wechselkurs ab, aber in jedem Fall gilt: Je energieeffizienter das Gerät ist, desto profitabler ist es. Für denjenigen, der sein Glück beim Bitcoin-Schürfen versuchen will, dürftedieses Bitcoin-Schürfgerät die beste Wahl sein.

Bitcoin-Schürf-Software

Es gibt grundsätzlich zwei Bitcoin-Schürfmethoden: Allein oder als Mitglied eines Mining-Pools beziehungsweise überCloud-Mining mit Schürfverträgen. Vor Bitcoin-Betrug beim Cloud-Mining sollte man sich auf jeden Fall in Acht nehmen.Fast jeder, der Bitcoins schürft, entscheidet sich für einen Mining-Pool, um die Bedeutung des Zufalls während des Schürfvorgangs zu minimieren. Bevor man einem Pool beitritt, benötigt man eine Bitcoin-Wallet, eine digitale Geldbörse zum Lagern der Bitcoins. Anschließend tritt man einem Mining-Pool bei und muss das Schürfgerät (bzw. mehrere)mit dem Pool verbinden. Beim Pool-Mining werden alle aus den erzeugten Blöcken gezogenen Gewinne unter den Mitgliedern des Pools geteilt, der individuelle Anteil hängt davon ab, wie viele Hashs das Mitglied beigesteuert hat.

Wie viel Bandbreite benötigt man, um Bitcoins zu schürfen? Mit einem Bitcoin-Schürfgerät in einem Pool dürfte die Bandbreite mit 10 Megabyte pro Tag vernachlässigbar klein gering sein. Was man aber unbedingt braucht, ist eine besonders gute Konnektivität, damit man alle Updates zur Arbeitso schnell wie möglich erhält.

Wer als Mitglied eines Pools schürft, bekommt häufigere, gleichmäßige Auszahlungen (man spricht auch vom Reduzieren der Varianz), aber die Auszahlungen können wegen möglicher Gebühren, die der Pool erhebt, geringer ausfallen. Beim selbständigen Schürfen erhält man große, aber seltene Auszahlungen; beim Pool-Schürfen erhält man kleine, aber häufige Auszahlungen. Langfristig ergibt sich bei beiden Methoden die gleiche Summe, sofern man in einem gebührenfreien Pool schürft.

Bitcoin-Cloud-Mining

Durch das Abschließen von Cloud-Mining-Verträgen können Investoren Bitcoins verdienen, ohne sich mit Dingen wie Schürf-Hardware, Software, Elektrizität, Bandbreite und anderen Offline-Problemen befassen zu müssen.

Die folgende Liste ist NICHT dazu bestimmt, einzelne Dienste zu empfehlen. Sie dient lediglich dazu, Cloud-Mining-Anbieter zu vergleichen. In der Vergangenheit hat es eine enorme Zahl von Betrugsfällen im Zusammenhang mit Bitcoin und Cloud-Mining gegeben.

Bewertung Hashflare: Hashflare bietet SHA-256-Schürfverträge an und es können die profitableren SHA-256-Coins geschürft werden, automatische Auszahlungen werden jedoch in Bitcoin vorgenommen. Kunden müssen mindestens 10 GHash/s kaufen.

Bewertung Genesis Mining: Genesis Mining ist der größte Anbieter von Bitcoin- und Scrypt-Cloud-Mining. Genesis Mining bietet drei Tarife für Bitcoin-Cloud-Mining zu angemessenen Preisen an. Es sind auch Zcash-Schürfverträge erhältlich.

Bewertung Hashing 24: Hashing24 ist seit 2012 im Bitcoin-Schürfen aktiv.Der Anbieter betreibt Standorte in Island und Georgien. Er verwendet moderne ASIC-Chips von BitFury, welche die stärkste Leistung und größte Effizienz liefern, die möglich ist.

Was ist Bitcoin-Mining?

Bitcoin-Mining, also das Schürfen von Bitcoins, ist ein Prozess, bei dem in einer öffentlichen Transaktionsdatenbank sämtliche jemals durchgeführten Transaktionen verzeichnet werden. Diese Datenbank mit Transaktionen aus der Vergangenheitwird Blockchain genannt, weil sie eine Kette aus Blöcken darstellt.Die Blockchain dient den Mitgliedern des Netzwerks als Bestätigung, dass die Transaktionen stattgefunden haben.

Die Bitcoin-Knoten unterscheiden mithilfe der Blockchain legitime Bitcoin-Transaktionen von Versuchen, bereits ausgegebene Coins erneut auszugeben.

Das Bitcoin-Schürfen ist ganz bewusst so angelegt, dass es ressourcenintensiv und schwierig ist. So bleibt die Zahl der Blöcke, die pro Tag von den Schürfern gefunden werden, konstant. Die einzelnen Blöcke müssen einen sogenannten Proof of Work (deutsch etwa Arbeitsnachweis) enthalten, um als gültig anerkannt zu werden.Dieser Proof of Work wird von den anderen Bitcoin-Knoten jedes Mal überprüft, wenn sie einen Block erhalten. Bitcoin arbeitet mit der Proof-of-Work-Funktion Hashcash.

Das Hauptziel beim Schürfen ist, dass die Knoten ein sicheres, manipulationssicheres Maß an Übereinstimmung erreichen. Das Schürfen dient auch als ein Mechanismus, um Bitcoins ins System einzuführen: Schürfer bekommen alle Transaktionsgebühren bezahltund erhalten einen „Zuschuss” in Form von neu erzeugten Bitcoins.

Das dient zum einen dazu, neue Münzen auf dezentrale Weise zu verteilen; zum anderen sollen Leute dazu motiviert werden, zur Sicherheit des Systems beizutragen.

Das Bitcoin-Mining, das Schürfen von Bitcoins, heißt so, weil es dem Abbau anderer Rohstoffe ähnelt: Es erfordert Aufwand und es stellt neue Einheiten einer Währung in einem langsamen Tempo zur Verfügung, das der Geschwindigkeit ähnelt, mit der beispielsweise Gold aus dem Boden gewonnen wird.

Was ist der Proof of Work?

Ein Proof of Work (deutsch etwa Arbeitsnachweis) ist ein Datensatz, der schwierig (teuer, zeitaufwändig) zu produzieren war, weil bestimmte Anforderungen zu erfüllen waren. Es muss problemlos überprüfbar sein, ob die Daten den besagten Anforderungen genügen.

Das Erzeugen eines Proof of Work kann ein zufallsbasierter Vorgang mit geringer Profitabilität sein. Deshalb sind in der Regel viele Versuche erforderlich, bis ein gültiger Proof of Work generiert werden kann.Bitcoin arbeitet mit der Proof-of-Work-Funktion Hashcash.

Was hat es mit der Mining-Schwierigkeit auf sich?

Das schwierige Rechenproblem

Es ist schwierig, mit Bitcoin einen Block zu erzeugen, weil der SHA-256-Hash am Anfang (Blockheader) eines Blocks kleiner oder gleich dem Ziel sein muss, damit der Block vom Netzwerk akzeptiert wird.

Vereinfacht ausgedrückt: Der Hash eines Blocks muss mit einer bestimmten Anzahl von Nullen beginnen. Da die Wahrscheinlichkeit, einen Hash zu berechnen, der mit vielen Nullen beginnt, sehr gering ist, werden viele Versuche benötigt. Um in jeder Runde einen neuen Hash zu erzeugen, wird eine Nonce inkrementiert. Weitere Informationen unter „Proof of Work”.

Der Schwierigkeitsgrad beim Bitcoin-Mining

Der Schwierigkeitsgrad beim Bitcoin-Mining drückt aus, wie schwierig es ist, einen neuen Block zu finden, verglichen mit der leichtesten vorhandenen Möglichkeit. Das System berechnet die Schwierigkeit alle 2016 Blöcke neu. Der dabei ermittelte Wert entspricht der Schwierigkeit, mit der das gesamte Netzwerk exakt zwei Wochen lang hätte schürfen müssen, um die vorangegangenen 2016 Blöcke zu erzeugen. So entsteht im Durchschnitt alle zehn Minuten ein Block.

Je mehr Schürfer teilnehmen, desto mehr steigt die Geschwindigkeit, mit der Blöcke erzeugt werden. Dadurch steigt wiederum der Schwierigkeitsgrad, um die höhere Geschwindigkeit zu kompensieren, und die Blöcke werden wieder langsamer erzeugt. Jegliche von böswilligen Schürfern veröffentlichten Blöcke, die nicht der geforderten Ziel-Schwierigkeit entsprechen, werden von allen anderen Netzwerkmitgliedern einfach abgelehnt und sind damit wertlos.

Die Block-Belohnung

Wird ein Block gefunden, kann sich der Erzeuger selbst mit einer bestimmten Anzahl von Bitcoins belohnen, wobei das Einverständnis sämtlicher Netzwerkmitglieder erforderlich ist. Derzeit liegt diese Prämie bei 25 Bitcoins; der Wert halbiert sich alle 210.000 Blöcke. Siehe auch „Kontrollierte Geldmenge” oder verwenden Sie einen Bitcoin-Mining-Rechner.

Außerdem erhält der Schürfer Gebühren, die Nutzer für Transaktionen zahlen, als Belohnung. Das bietet ihm einen Anreiz, um die Transaktion in seinen Block einzubeziehen. In Zukunft, wenn die Zahl neuer Bitcoins, die ein Schürfer pro Block erzeugen darf, kleiner wird, werden die Gebühren einen weit größeren Anteil am Schürfeinkommen haben.

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.

Bitcoin Profitability Calculator – BTC Mining Profit Calculator

Enter your set up information in the form below. Do not enter commas, only dots for decimal separator.

Nothing guaranteed, of course this is only a rough estimate!
Do not enter commas, only dots for decimal separator. You can also calculate rented mining by setting “Power consumption” to 0 and “Cost of mining hardware” to the rent per time frame. Default values are for a system of four 6870s.

Estimate Strategy

Extrapolating bitcoin difficulty or price is pure voodoo. It is much easier to predict the relationship of the two parameters in form of the Mining Factor. The Mining Factor 100 is the value in USD of the bitcoins you can generate if you let a 100MHash/s miner run for 24 hours. If the Mining Factor 100 rises above $2 or so everybody buys mining equipment and thus increases difficulty. If it falls people will stop mining eventually. The estimate starts with the current Mining Factor and decreases it exponentially such that the decrease accounts for the factor decline per year. Please note that a profit/loss by holding the coins is not accounted for in this estimate.

Bitcoin Mining Hardware Guide

The best Bitcoin mining hardware has evolved dramatically since 2009

At first, miners used their central processing unit (CPU) to mine, but soon this wasn't fast enough and it bogged down the system resources of the host computer. Miners quickly moved on to using the graphical processing unit (GPU) in computer graphics cards because they were able to hash data 50 to 100 times faster and consumed much less power per unit of work.

During the winter of 2011, a new industry sprang up with custom equipment that pushed the performance standards even higher. The first wave of these specialty bitcoin mining devices were easy to use Bitcoin miners were based on field-programmable gate array (FPGA) processors and attached to computers using a convenient USB connection.

FPGA miners used much less power than CPU's or GPU's and made concentrated mining farms possible for the first time.

Today's modern and best bitcoin mining hardware

Application-specific integrated circuit (ASIC) miners have taken over completely. These ASIC machines mine at unprecedented speeds while consuming much less power than FPGA or GPU mining rigs. Several reputable companies have established themselves with excellent products.

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

Best Bitcoin Mining Hardware

Two major factors go into determining the best bitcoin mining hardware: (1) cost and (2) electricity efficiency.

Bitcoin mining is difficult to do profitably but if you try then this Bitcoin miner is probably a good shot.

ASIC Bitcoin Mining Hardware

Application-specific integrated circuit chips (ASICs) are bitcoin mining hardware created solely to solve Bitcoin blocks. They have only minimal requirements for other normal computer applications. Consequently, ASIC Bitcoin mining systems can solve Bitcoin blocks much quicker and use less less electricity or power than older bitcoin mining hardware like CPUs, GPUs or FPGAs.

As Bitcoin mining increases in popularity and the Bitcoin price rises so does the value of ASIC Bitcoin mining hardware. As more Bitcoin mining hardware is deployed to secure the Bitcoin network the Bitcoin difficulty rises. This makes it impossible to profitably compete without a Bitcoin ASIC system. Furthermore, Bitcoin ASIC technology keeps getting faster, more efficient and more productive so it keeps pushing the limits of what makes the best Bitcoin mining hardware.

Some models of Bitcoin miners include Antminer S5, Antminer U3, ASICMiner BE Tube, ASICMiner BE Prisma, Avalon 2, Avalon 3, BTC Garden AM-V1 616 GH/s, VMC PLATINUM 6 MODULE, and USB miners.

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.

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.
