I got rich mining bitcoins without special hardware

What exactly is mining? There are three primary ways to obtain bitcoins: buying on an exchange, accepting them for goods and services, and mining new ones. In reality, it's simply the verification of bitcoin transactions. For example, Eric buys a TV from Nicole with a bitcoin. In order to make sure his bitcoin is a genuine bitcoin, miners begin to verify the transaction. It's not just one transaction individuals are trying to verify; it's many.

All the transactions are gathered into boxes with a virtual padlock on them—called "block chains. Once their computer finds it, the box pops open and the transactions are verified. For finding that "needle in a haystack" key, the miner gets a reward of 25 newly generated bitcoins.

The current number of attempts it takes to find the correct key is around 1,,, Despite that many attempts, the bitcoin reward is given out about every 10 minutes. In , the bitcoin reward for verifying transactions will halve to Read more : Why the Internet may never be the same again. How do you mine on a budget? Bitcoin mining can be done by a computer novice—requiring basic software and specialized hardware. The software required to mine is straightforward to use and open source—meaning free to download and run.

A prospective miner needs a bitcoin wallet—an encrypted online bank account—to hold what is earned. The problem is, as in most bitcoin scenarios, wallets are unregulated and prone to attacks. When bitcoins are lost or stolen they are completely gone, just like cash. With no central bank backing your bitcoins, there is no possible way to recoup your loses. The second piece of software needed is the mining software itself—the most popular is called GUIMiner.

When launched, the program begins to mine on its own—looking for the magic combination that will open that padlock to the block of transactions. The program keeps running and the faster and more powerful a miner's PC is, the faster the miner will start generating bitcoins. When mining began, regular off-the-shelf PCs were fast enough to generate bitcoins.

That's the way the system was set up—easier to mine in the beginning, harder to mine as more bitcoins are generated. Over the last few years, miners have had to move on to faster hardware in order to keep generating new bitcoins. Today, application-specific integrated circuits ASIC are being used. You may have heard that miners are solving difficult mathematical problems—that's true but not because the math itself is hard.

What they're actually doing is trying to be the first miner to come up with a digit hexadecimal number a " hash " that is less than or equal to the target hash. It's basically guesswork. So it is a matter of randomness, but with the total number of possible guesses for each of these problems numbering in the trillions, it's incredibly arduous work.

And the number of possible solutions referred to as the level of mining difficulty only increases with each miner that joins the mining network. In order to solve a problem first, miners need a lot of computing power. Aside from the short-term payoff of newly minted bitcoins, being a coin miner can also give you "voting" power when changes are proposed in the Bitcoin network protocol.

In other words, miners have some degree of influence on the decision-making process for matters such as forking. The more hash power you possess, the more votes you have to cast for such initiatives. The rewards for Bitcoin mining are reduced by half roughly every four years. When bitcoin was first mined in , mining one block would earn you 50 BTC. In , this was halved to 25 BTC.

By , this was halved again to On May 11, , the reward halved again to 6. Not a bad incentive to solve that complex hash problem detailed above, it might seem. To keep track of precisely when these halvings will occur, you can consult the Bitcoin Clock , which updates this information in real time.

Interestingly, the market price of Bitcoin has, throughout its history, tended to correspond closely to the reduction of new coins entered into circulation. This lowering inflation rate increased scarcity and, historically, the price has risen with it. If you want to estimate how much bitcoin you could mine with your mining rig's hash rate, the site CryptoCompare offers a helpful calculator. Other web resources offer similar tools. Although individuals were able to compete for blocks with a regular at-home personal computer early on in Bitcoin's history, this is no longer the case.

The reason for this is that the difficulty of mining Bitcoin changes over time. In order to ensure the blockchain functions smoothly and can process and verify transactions, the Bitcoin network aims to have one block produced every 10 minutes or so. However, if there are 1 million mining rigs competing to solve the hash problem, they'll likely reach a solution faster than a scenario in which 10 mining rigs are working on the same problem.

For that reason, Bitcoin is designed to evaluate and adjust the difficulty of mining every 2, blocks, or roughly every two weeks. When there is more computing power collectively working to mine for bitcoins, the difficulty level of mining increases in order to keep block production at a stable rate. Less computing power means the difficulty level decreases.

At today's network size, a personal computer mining for bitcoin will almost certainly find nothing. All of this is to say that, in order to mine competitively, miners must now invest in powerful computer equipment like a graphics processing unit GPU or, more realistically, an application-specific integrated circuit ASIC. Some miners—particularly Ethereum miners—buy individual graphics cards as a low-cost way to cobble together mining operations.

Today, Bitcoin mining hardware is almost entirely made up of ASIC machines, which in this case, specifically do one thing and one thing only: Mine for bitcoins. Today's ASICs are many orders of magnitude more powerful than CPUs or GPUs and gain both more hashing power and energy efficiency every few months as new chips are developed and deployed. Say I tell three friends that I'm thinking of a number between one and , and I write that number on a piece of paper and seal it in an envelope.

My friends don't have to guess the exact number; they just have to be the first person to guess any number that is less than or equal to it. And there is no limit to how many guesses they get. Let's say I'm thinking of the number There is no "extra credit" for Friend B, even though B's answer was closer to the target answer of Now imagine that I pose the "guess what number I'm thinking of" question, but I'm not asking just three friends, and I'm not thinking of a number between 1 and Rather, I'm asking millions of would-be miners, and I'm thinking of a digit hexadecimal number.

Now you see that it's going to be extremely hard to guess the right answer. If B and C both answer simultaneously, then the system breaks down. In Bitcoin terms, simultaneous answers occur frequently, but at the end of the day, there can only be one winning answer. Typically, it is the miner who has done the most work or, in other words, the one that verifies the most transactions.

The losing block then becomes an " orphan block. Miners who successfully solve the hash problem but haven't verified the most transactions are not rewarded with bitcoin. Here is an example of such a number:. The number above has 64 digits.

Easy enough to understand so far. As you probably noticed, that number consists not just of numbers, but also letters of the alphabet. Why is that? To understand what these letters are doing in the middle of numbers, let's unpack the word "hexadecimal.

The decimal system uses factors of as its base e. This, in turn, means that every digit of a multi-digit number has possibilities, zero through In computing, the decimal system is simplified to base 10, or zero through nine. In a hexadecimal system, each digit has 16 possibilities.

But our numeric system only offers 10 ways of representing numbers zero through nine. If you are mining Bitcoin, you do not need to calculate the total value of that digit number the hash. I repeat: You do not need to calculate the total value of a hash. Remember that analogy, in which the number 19 was written on a piece of paper and put in a sealed envelope? In Bitcoin mining terms, that metaphorical undisclosed number in the envelope is called the target hash.

What miners are doing with those huge computers and dozens of cooling fans is guessing at the target hash. Miners make these guesses by randomly generating as many " nonces " as possible, as quickly as possible. A nonce is short for "number only used once," and the nonce is the key to generating these bit hexadecimal numbers I keep mentioning.

In Bitcoin mining, a nonce is 32 bits in size—much smaller than the hash, which is bits. The first miner whose nonce generates a hash that is less than or equal to the target hash is awarded credit for completing that block and is awarded the spoils of 6.

In theory, you could achieve the same goal by rolling a sided die 64 times to arrive at random numbers, but why on Earth would you want to do that? The screenshot below, taken from the site Blockchain. You are looking at a summary of everything that happened when block No. The nonce that generated the "winning" hash was The target hash is shown on top.

The term "Relayed by AntPool" refers to the fact that this particular block was completed by AntPool, one of the more successful mining pools more about mining pools below. As you see here, their contribution to the Bitcoin community is that they confirmed 1, transactions for this block. If you really want to see all 1, of those transactions for this block, go to this page and scroll down to the Transactions section.

Source : Blockchain. All target hashes begin with a string of leading zeroes. There is no minimum target, but there is a maximum target set by the Bitcoin Protocol. No target can be greater than this number:. The winning hash for a bitcoin miner is one that has at least the minimum number of leading zeroes defined by the mining difficulty.

Here are some examples of randomized hashes and the criteria for whether they will lead to success for the miner:. To find such a hash value, you have to get a fast mining rig, or, more realistically, join a mining pool—a group of coin miners who combine their computing power and split the mined Bitcoin. Mining pools are comparable to Powerball clubs whose members buy lottery tickets en masse and agree to share any winnings. A disproportionately large number of blocks are mined by pools rather than by individual miners.

In other words, it's literally just a numbers game. You cannot guess the pattern or make a prediction based on previous target hashes. At today's difficulty levels, the odds of finding the winning value for a single hash is one in the tens of trillions.

Not great odds if you're working on your own, even with a tremendously powerful mining rig. Not only do miners have to factor in the costs associated with expensive equipment necessary to stand a chance of solving a hash problem, but they must also consider the significant amount of electrical power mining rigs utilize in generating vast quantities of nonces in search of the solution.

All told, Bitcoin mining is largely unprofitable for most individual miners as of this writing. The site CryptoCompare offers a helpful calculator that allows you to plug in numbers such as your hash speed and electricity costs to estimate the costs and benefits. Source : CryptoCompare. The miner who discovers a solution to the puzzle first receives the mining rewards, and the probability that a participant will be the one to discover the solution is equal to the proportion of the total mining power on the network.

Participants with a small percentage of the mining power stand a very small chance of discovering the next block on their own. For instance, a mining card that one could purchase for a couple of thousand dollars would represent less than 0. With such a small chance at finding the next block, it could be a long time before that miner finds a block, and the difficulty going up makes things even worse.

The miner may never recoup their investment. The answer to this problem is mining pools. Mining pools are operated by third parties and coordinate groups of miners. By working together in a pool and sharing the payouts among all participants, miners can get a steady flow of bitcoin starting the day they activate their miners.

Statistics on some of the mining pools can be seen on Blockchain. As mentioned above, the easiest way to acquire Bitcoin is to simply buy it on one of the many Bitcoin exchanges. Alternately, you can always leverage the "pickaxe strategy.

To put it in modern terms, invest in the companies that manufacture those pickaxes. In a cryptocurrency context, the pickaxe equivalent would be a company that manufactures equipment used for Bitcoin mining. The risks of mining are often financial and regulatory.

As aforementioned, Bitcoin mining, and mining in general, is a financial risk because one could go through all the effort of purchasing hundreds or thousands of dollars worth of mining equipment only to have no return on their investment. That said, this risk can be mitigated by joining mining pools. If you are considering mining and live in an area where it is prohibited, you should reconsider.

It may also be a good idea to research your country's regulation and overall sentiment toward cryptocurrency before investing in mining equipment. One additional potential risk from the growth of Bitcoin mining and other PoW systems as well is the increasing energy usage required by the computer systems running the mining algorithms. Though microchip efficiency has increased dramatically for ASIC chips, the growth of the network itself is outpacing technological progress.

As a result, there are concerns about Bitcoin mining's environmental impact and carbon footprint. There are, however, efforts to mitigate this negative externality by seeking cleaner and green energy sources for mining operations such as geothermal or solar sources , as well as utilizing carbon offset credits.

Switching to less energy-intensive consensus mechanisms like proof-of-stake PoS , which Ethereum has transitioned to, is another strategy; however, PoS comes with its own set of drawbacks and inefficiencies, such as incentivizing hoarding instead of using coins and a risk of centralization of consensus control.

Mining is a metaphor for introducing new bitcoins into the system because it requires computational work just as mining for gold or silver requires physical effort. Of course, the tokens that miners find are virtual and exist only within the digital ledger of the Bitcoin blockchain.

At this stage, the miner is rewarded with a certain number of Bitcoins, currently set at In addition to the Bitcoins received, the minor will also be awarded the transaction fees paid by users within the successfully mined block, which is of far greater incentive for miners as the number of Bitcoins per block continues to decline. The end to end process can perhaps be best described by the following chart that incorporates the various steps involved from mining to ultimately receiving well-earned Bitcoins and transaction fees:.

It boils down to the location of the Bitcoin mining hardware. For the Bitcoin miner, the user will buy and set up and maintain the Bitcoin mining rigs, which is not something for the technophobes as sizeable electricity costs also a consideration, mining rigs requiring plenty of ventilation and cooling, not to mention processing.

Cloud mining is supported by mining companies setting up the mining rigs at their own facility, with a cloud miner only needing to register and purchase shares or a mining contract. The user essentially buying a proportion of the Bitcoin miners hash power. However, as miners have continued to use their technical abilities to develop hardware capable of earning at a much greater number of Bitcoins, leaving CPU and laptop users behind, using a laptop is now unlikely to yield a single Bitcoin even if mining for years.

The use of GPUs increased mining power by as much as x, with significantly less power usage, saving on sizeable electricity bills. Next came FPGAs, Field Programmable Gate Aray , the improvement here being in the power usage rather than actual mining speed, with mining speeds slower than GPUs, while power consumption fell by as much as 5x. Power savings led to the evolution of mining farms and the Bitcoin mining industry as it is known today, where Bitcoin mining power is controlled by a mining few more commonly known as the Bitcoin Cartel.

Evolution of software has slowed, with nothing in the marketplace at present or in development that is expected to replace ASICs, with ASIC chips likely to see minor tweaks at best to try and squeeze out greater efficiencies , though it will only be a matter of time before the Bitcoin world comes up with something newer and faster as miners catch up on hashing power.

Proof of work is also referred to as PoW. All of the blocks in a Bitcoin blockchain have a series of data referred to as nonces, these are meaningless data strings attached to each block of a Bitcoin blockchain. The proof of work is therefore difficult to produce, while considered simple to verify, the production of a proof of work being a random process, requiring mining rigs to calculate as many computations per second as possible so as to increase the probability of producing the proof of work.

Bitcoin mining difficulty is the degree of difficulty in finding a given hash below the target during the proof of work. As mining difficulty increases, target value declines and vice-versa. In basic terms, as more miners join the Bitcoin network, the rate of block creation increases, leading to faster mining times. As mining times speed up, mining difficulty is increased, bringing the block creation rate back down to the desired 10 minutes as mentioned previously.

Once the mining difficulty is increased, the average mining time returns to normal and the cycle repeats itself about every 2-weeks. Wallets can be downloaded for free as can miner programs and once downloaded its ready to go. The reality is that your desktop computer or laptop will just not cut it in the mining world, so the options are to either make a sizeable investment and create a mining rig, or joining a mining pool or even subscribe to a cloud mining service, the latter requiring some degree of due diligence as is the case with any type of investment.

In mining pools, the company running the mining pool charges a fee, whilst mining pools are capable of solving several blocks each day, giving miners who are part of a mining pool instant earnings. While you can try to mine with GPUs and gaming machines, income is particularly low and miners may, in fact, lose money rather than make it, which leaves the more expensive alternative of dedicated ASICs hardware. Miners make Bitcoin by finding proof of work and creating blocks, with the current number of Bitcoins the miner receives per block creation standing at Can you get rich off the mining process?

By : Bob Mason. Bitcoin mining is the validation of transactions that take place on each Bitcoin block. Mentioned in Article. What is Bitcoin Mining? What is Bitcoin Mining Difficulty? Miners will then receive transaction fees in the form of newly created Bitcoins. From Start to Finish: Bundle Transactions, Validation, Proof of Work, Blockchains and the Network The end to end process can perhaps be best described by the following chart that incorporates the various steps involved from mining to ultimately receiving well-earned Bitcoins and transaction fees: Bitcoin Mining Step-by-Step Verify if transactions are valid.

Transactions are bundled into a block The header of the most recent block is selected and entered into the new block as a hash. Proof of work is completed. A new block is added to the blockchain and added to the peer-to-peer network. Proof of Work Step-by-Step A new block is proposed.

Pool payouts in Nano cost you nothing. That is why we came up with another solution: payouts in Bitcoin. What can be better? Now you can get payouts in the Ethereum pool for free every day even if you have only one graphics card. Also, Nicehash and other mining rental platforms are supported.

We currently use such cryptocurrency exchanges as Kraken and Binance. Cryptocurrencies are always exchanged at market price. Say, your payout threshold is 0. You accumulate 0. The pool sends your 0. As a result, you get the equivalent of 0. Say, you earn 0. We know that many users mine directly to an exchange. Exchanges often have a deposit threshold.

For example, a minimum deposit on Kraken is 0. That is why we set a threshold for payouts in NANO in the pool: the equivalent of 0. Even the weakest GPU that mines Ethereum can accumulate the required minimum in one day. Payouts are processed once a day at UTC. Payouts are not instant. Considering that your ETH must be transferred to an exchange, exchanged, and then transferred back, the whole process usually takes no more than two hours allowing for small delays.

We plan to process the payouts more than once a day in the future. The whole process is completely transparent. After the pool issues a payout and even during the payout process , you can monitor the operation status of an exchange system, check an exchange rate, track your money from the moment ETH is sent to exchange to the moment you get NANO. We made Bitcoin mining on GPU a reality. Payouts are issued once a day at UTC. The whole process usually takes no more than two hours allowing for small delays like waiting for exchanged BTC withdrawn from an exchange.

When miners get payouts from our payment gateway, they pay only a part of the transaction fee in the Bitcoin network. We group all miner payouts in one transaction. The transaction expenses are then divided between the miners in equal parts. All other fees are covered by the pool, including the fee for sending ETH to an exchange and the fee for withdrawing BTC from an exchange. After the pool issues a payout and even during the payout process , you can monitor the operation status of an exchange system, check an exchange rate, track your money from the moment ETH is sent to exchange to the moment you get BTC.

The pool will take care of all conversions with minimal fees. The principle is simple: when you enter your wallet address you need to use your Bitcoin or NANO address. We remind you that RaveOS is absolutely free if you mine in 2Miners pool. First, select your preferred mining client and then set up the simple configuration:. Please pay attention that when you add the wallet address you select the ETH Coin. If you mine Ethereum in the 2Miners pool, you can choose one of three cryptocurrencies for payouts: Ethereum, Bitcoin, or Nano.

The minimum payout in Ethereum is 0. Payouts in ETH are issued within two hours after you reach your payout threshold. No special setup is needed to use auto-exchange. We might also add auto-exchange for other cryptocurrencies in our pools in the future.
