As of February , the Chinese Government has halted trading of virtual currency, banned initial coin offerings and shut down mining. Many Chinese miners have. By mining, you can earn cryptocurrency without having to put down money for it. Bitcoin miners receive bitcoin as a reward for completing "blocks" of verified. Bitcoin Cash (BCH) mining requires three things: a dedicated mining setup (rig) or a mining pool that does all the heavy lifting, a wallet for collecting.

Abstract Bitcoin is a peer-to-peer electronic cash system that uses a decentralized architecture. But for most people, the prospects for Bitcoin mining are not good due to its complex nature and high costs. Here are the basics on how Bitcoin mining works and some key risks to be aware of.
Bitcoin is one of the most popular types of cryptocurrencies, which are digital mediums of exchange that exist solely online. Bitcoin runs on a decentralized computer network or distributed ledger that tracks transactions in the cryptocurrency. When computers on the network verify and process transactions, new bitcoins are created, or mined.
These networked computers, or miners, process the transaction in exchange for a payment in Bitcoin. Bitcoin is powered by blockchain, which is the technology that powers many cryptocurrencies. A blockchain is a decentralized ledger of all the transactions across a network. Groups of approved transactions together form a block and are joined to create a chain. Think of it as a long public record that functions almost like a long running receipt.
Bitcoin mining is the process of adding a block to the chain. In order to successfully add a block, Bitcoin miners compete to solve extremely complex math problems that require the use of expensive computers and enormous amounts of electricity.
ASICs consume huge amounts of electricity, which has drawn criticism from environmental groups and limits the profitability of miners. If a miner is able to successfully add a block to the blockchain, they will receive 6. The reward amount is cut in half roughly every four years, or every , blocks. But the price of bitcoin has been highly volatile , which makes it difficult or impossible for miners to know what their payment might be worth whenever they receive it.
It depends. The electricity for one ASIC can use the same amount of electricity as half a million PlayStation 3 devices, according to a report from the Congressional Research Service. One way to share some of the high costs of mining is by joining a mining pool.
Pools allow miners to share resources and add more capability, but shared resources mean shared rewards, so the potential payout is less when working through a pool. The IRS has been looking to crack down on owners and traders of cryptocurrencies as the asset prices have ballooned in recent years. Here are the key tax considerations to keep in mind for Bitcoin mining. Your return is based on selling it to someone else for a higher price, and that price may not be high enough for you to turn a profit.

There is one condition to it that you would be able to cash out your Bitcoin into the bank account you used to purchase cryptocurrency on Coinbase. If you have not purchased any cryptocurrency through them, then you would have to buy a small amount from them so that the money can be cashed out in your account. Fees: The fee they charge depends on the country in which your bank account is. Cash-out times: The time in which the amount gets credited to your account would also vary from country to country.
For example, in the US, the withdrawal time ranges from working days, whereas in the EU, it just takes working days. The first step is to open an account with Coinbase and then link your bank account with them. Once this is done that deposit in that account. If you already have an account with them, then skip this step and move to Step 2. As you have established your account now, you are required to transfer your Bitcoin to the Coinbase Bitcoin address provided to you.
Now comes the most significant step: to cash out Bitcoin in the wallet. When you see your wallet, there would be Bitcoin in it plus your default first currency as well. The deposit would show the amount as per your currency and the location that you chose.
It would also reflect your withdrawal limit. You would have to exchange the money in your local currency before withdrawing the amount. For instance, you just need to put the amount you wish to sell your Bitcoin for, and the fiat currency would automatically update the equivalent amount. This would be the same account of which you gave the details in the first step. The process might seem lengthy, but it is not; you would just take a couple of minutes to set up the account and cash out Bitcoin.
Kraken is another well-known exchange that enables withdrawals and fiat currency deposits quickly. This exchange was established in , and the maximum transactions that they process are Bitcoin to Euro. There are a few things that one must keep in mind before converting all the Bitcoins to your bank account-. Taxes: It is rightly said that taxes and death are two imminent things.
Even the Bitcoin investors would have to pay the tax for the money they get converted into their bank accounts. Although there are a few jurisdictions that have not provided any clarity about bitcoins and taxes. Yet, some tax authorities say that you will have to pay the tax on the profits you make if you sell Bitcoin for cash. Fees: Mostly, all the Bitcoin to bank account methods charge a fee for it.
Therefore, you will have to analyze the fee of all the exchanges before choosing one. But, if you still want to convert your Bitcoin into cash, then always check a few things such as ease of transaction, charges, whether you want to get it deposited to the bank account or PayPal account, currency in which you want to get it converted and how long you can wait to get the amount credited to your bank account.
The various factors that you should consider are the amount that needs to be cashed, the fee they charge, the safety of funds, and the period in which you want the amount to be credited to your account. So choose wisely and spend less while cashing out your Bitcoins. Sushma is a full-time blogger and financial expert.

How to Cash Out Bitcoin Easily Things to consider when cashing out Bitcoin There are a few things that you should consider while checking out the mode of converting Bitcoin into cash: Analyze the transaction fee of different modes so that you can select the one which offers more in less price The next important thing to check is the steps required in every process.
Choosing a method with lengthy steps can be monotonous and complicated as well sometimes. See the amount you want to withdraw as if the amount is less than your criteria; you might change your mind. Ask yourself if you wish to deposit the money in the bank account or your PayPal account. Check the period as to how much time it will take to credit in your account.
Last but not least, always study the local rules and guidelines before opting for any method These were the few things that you should look at before choosing any payment method.

Goldman Sachs launched an altcoin trading desk and offers altcoin products in The bitcoin reward that miners receive is an incentive that motivates people to assist in the primary purpose of mining: to legitimize and monitor Bitcoin transactions, ensuring their validity. Because many users all over the world share these responsibilities, Bitcoin is a "decentralized" cryptocurrency, or one that does not rely on any central authority like a central bank or government to oversee its regulation.
However, before you invest the time and equipment, read this explainer to see whether mining is really for you. Throughout, we use "Bitcoin" with a capital "B" when referring to the network or the cryptocurrency as a concept, and "bitcoin" with a small "b" when we're referring to a quantity of individual tokens. Blockchain "mining" is a metaphor for the computational work that nodes in the network undertake in hopes of earning new tokens.
In reality, miners are essentially getting paid for their work as auditors. They are doing the work of verifying the legitimacy of Bitcoin transactions. This convention is meant to keep Bitcoin users honest and was conceived by Bitcoin's founder, Satoshi Nakamoto. By verifying transactions, miners are helping to prevent the " double-spending problem. Double spending is a scenario in which a Bitcoin owner illicitly spends the same bitcoin twice. Though counterfeit cash is possible, it is not exactly the same as literally spending the same dollar twice.
With digital currency, however, as the Investopedia dictionary explains, "there is a risk that the holder could make a copy of the digital token and send it to a merchant or another party while retaining the original. If you were to try to spend both the real bill and the fake one, someone who took the trouble of looking at both of the bills' serial numbers would see that they were the same number, and thus one of them had to be false.
What a blockchain miner does is analogous to that—they check transactions to make sure that users have not illegitimately tried to spend the same bitcoin twice. This isn't a perfect analogy—we'll explain in more detail below. Only 1 megabyte of transaction data can fit into a single bitcoin block.
The 1MB limit was set by Satoshi Nakamoto, and this has become a matter of controversy because some miners believe the block size should increase to accommodate more data, which would effectively mean that the Bitcoin network could process and verify transactions more quickly. In addition to lining the pockets of miners and supporting the Bitcoin ecosystem, mining serves another vital purpose: It is the only way to release new cryptocurrency into circulation.
In other words, miners are basically "minting" currency. For example, as of March , there were just under 19 million bitcoins in circulation, out of a total of 21 million. Aside from the coins minted via the genesis block the very first block, which founder Satoshi Nakamoto created , every single one of those bitcoins came into being because of miners.
In the absence of miners, Bitcoin as a network would still exist and be usable, but there would never be any additional bitcoin. However, because the rate of bitcoin "mined" is reduced over time, the final bitcoin won't be circulated until around the year This does not mean that transactions will cease to be verified. Miners will continue to verify transactions and will be paid fees for doing so in order to keep the integrity of Bitcoin's network.
To earn new bitcoins, you need to be the first miner to arrive at the right answer, or closest answer, to a numeric problem. This process is also known as proof of work PoW. To begin mining is to start engaging in this proof-of-work activity to find the answer to the puzzle. No advanced math or computation is really involved.
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.
