Dec 17, · Bitcoin is like digital gold in many ways. Like gold, bitcoin cannot simply be created arbitrarily; it requires work to "extract". While gold must be extracted from the physical earth, bitcoin . Nov 18, · Mining and Bitcoin Circulation 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.
Outsourcing bitcoin miningHow Does Bitcoin Mining Work?
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. 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 who haven't verified the most transactions are not rewarded with bitcoin. Well, 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. As you know, we use the "decimal" system, which means it is base This, in turn, means that every digit of a multi-digit number has 10 possibilities, 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. That's why you have to stick letters in, specifically letters a, b, c, d, e, and f.
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 ELI5 analogy, where I wrote the number 19 on a piece of paper and put it 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. A nonce is short for "number only used once," and the nonce is the key to generating these bit hexadecimal numbers I keep talking about. In Bitcoin mining, a nonce is 32 bits in size—much smaller than the hash, which is bits. 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 was mined. 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 transactions for this block.
If you really want to see all of those transactions for this block, go to this page and scroll down to the heading "Transactions. All target hashes begin with zeros—at least eight zeros and up to 63 zeros. There is no minimum target, but there is a maximum target set by the Bitcoin Protocol.
No target can be greater than this number:. Here are some examples of randomized hashes and the criteria for whether they will lead to success for the miner:. Note: These are made-up hashes. You'd 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 those 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. 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.
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. Source: Cryptocompare. Mining rewards are paid to the miner who discovers a solution to the puzzle first, and the probability that a participant will be the one to discover the solution is equal to the portion 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. 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 miner. As mentioned above, the easiest way to acquire bitcoin is to simply buy it on one of the many exchanges. Alternately, you can always leverage the "pickaxe strategy. Or, 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 legality of Bitcoin mining depends entirely on your geographic location. The concept of Bitcoin can threaten the dominance of fiat currencies and government control over the financial markets. For this reason, Bitcoin is completely illegal in certain places. Bitcoin ownership and mining are legal in more countries than not.
The risks of mining are that of financial risk and a regulatory one. As mentioned, Bitcoin mining, and mining in general, is a financial risk. 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 that it is prohibited you should reconsider.
It may also be a good idea to research your countries regulation and overall sentiment towards cryptocurrency before investing in mining equipment. Your Money. Personal Finance. Your Practice.

The Simple Explanation. A secure hardware wallet like the Ledger Nano X is a good option. It depends what your goals are with cloud mining. If your goal is to obtain bitcoins, then there is really no reason to cloud mine or even mine at all.
If you find a legitimate cloud mining operation and you are making profit, you will very likely need to pay taxes on that profit. The best way to determine the taxes you owe is to use a crypto tax software.
The reason there are so many cloud mining scams is because it is very easy for anyone in the world to setup a website. The company can act legit by sending initial payments to its customers. But after that it can just keep the already received payments for hash power and then make no further payments. Two of the most famous cloud mining companies have already been exposed as scams: HashOcean and Bitcoin Cloud Services.
Even as recently as September of , cloud mining scams are stealing people's money. The SEC equivalent of the Phillipines just issued a warning to customers of Mining City to get out now and have told promoters of the company that they could go to jail for up to 21 years if they don't stop immedietely.
Cloud mining scams are not a thing of the past. They very much so still happen today, so be vigilant or, better yet, just avoid them. If you beleive you have found a legitimate clound mining company, you can really make sure by putting it to the test.
NOTE: the following are taken largely from Puppet's Cloud Mining reddit post, which is a great supplement to this post. If you have purchased options for the right to some amount of hashing power, there is no reason why you shouldn't be able to direct that hashing power to any pool that you want. There are only a handful of ASIC manufacturers who could service a large scale mining operation with hardware.
Any cloud mining operation would not only allow an ASIC manufacturer to disclose a large ASIC purchase, but they'd also want them to do so to prove they are serious. So far, no cloud mining operation we are aware of has has an ASIC manufacturer acknowledge they are selling hardware to a cloud mining company.
Bitcoin mining is very competitive and has incredibly thin margins. There would be no way to mine profitably if they were paying not only you, but also the person who referred you. If there is no way to the know idenntity of the cloud mining operation, there is no way to hold them accountable if they run with the money. It also makes it harder to catch the person who stole your money.
WARNING: Just because a cloud mining website boasts a famous person as an investor or advisor does not mean that person is actually investing or advising. Anyone can throw up a picture of Elon Musk on their site. The real proof is if Elon Musk himself says in a news clip that he is a founder. Investments should never be a one-way transaction. If you can easily give the cloud miner money, but there is no obvious way to sell your position and get it back, then that is a good indication you will never get your money back.
Any investment that guarantees profits is a scam. If the cloud miner has so far made good on delivering its guarantees, it is because they are using funds from new investors to pay off old ones and appear solvent. Ponzi schemes work this way. Eventually, they are going to run with the money, but you never know when it will happen.
The other point to consider is: if a miner could guarantee profits, why would they sell that right to you? Why wouldn't they take teh guaranteed profits for themselves? If the amount of shares for sale in the cloud mining operation appear infinite, then they are definitely running a scam. No miner has an unlimited amount of hashing power. Most cloud mining companies accept Bitcoin, PayPal, and credit cards. If a cloud mining company accepts bitcoins then there is a good chance it is a scam.
This is because Bitcoin payments cannot be reversed. Once the scam company receives your bitcoin payment you have no way to get your coins back. Any company offering free trials, especially if they require payment information, is most likely a scam. Our guide on the best bitcoin wallets will help you pick one. Read it here! Cloud mining means a host company owns Bitcoin mining hardware and runs it at a professional mining facility. You pay the company and rent out some of the hardware.
Based on the amount of hash power you rent, you will earn a share of payments from the cloud mining company for any revenue generated by the hash power you purchased. In most cases, though, there is no mining facility or hardware. There is just a guy taking your money and paying part of it to someone who signed up before you did.
Eventually he runs away with the money, and you are left with nothing. Mining software is something you download on your computer. It is required when you OWN mining hardware. Software connects your hardware to the internet so that it can make hashes and communicate with the network. Just find an exchange in your country and buy some bitcoins. If you're still a bit confused about what Bitcoin mining is, that's okay.
That's one reason I built this site, to make it easier to understand! One common question people ask is if they can just invest in the mining companies instead of trying to mine themselves.
The answer is: yes, you absolutely can. And you wouldn't be the only ones investing in these companies. Fidelity, Vanguard, and Charles Schwab Funds have all been buying these stocks en masse. So when Jamie Dimon, CEO of Chase, denigrates Bitcoin , just remember that many of his friends at the big banks are loading up on these stocks themselves.

Is Bitcoin mining just free money?
Well, it's much, much more than that! If you want the full explanation on Bitcoin mining, keep reading Jordan Tuwiner Last updated December 1, Chapter 1 What is Bitcoin Mining?
Bitcoin mining is the backbone of the Bitcoin network. Miners provide security and confirm Bitcoin transactions. Without Bitcoin miners, the network would be attacked and dysfunctional.
Bitcoin mining is done by specialized computers. The role of miners is to secure the network and to process every Bitcoin transaction. For this service, miners are rewarded with newly-created Bitcoins and transaction fees. What is Bitcoin mining actually doing? Miners are securing the network and confirming Bitcoin transactions. Miners are paid rewards for their service every 10 minutes in the form of new bitcoins. What is Bitcoin Mining Actually Doing?
What is the point of Bitcoin mining? This is something we're asked everyday! There are many aspects and functions of Bitcoin mining and we'll go over them here.
They are: Issuance of new bitcoins Confirming transactions Security Mining Is Used to Issue new Bitcoins Traditional currencies--like the dollar or euro--are issued by central banks. Bitcoin is different. With Bitcoin, miners are rewarded new bitcoins every 10 minutes. Miners Confirm Transactions Miners include transactions sent on the Bitcoin network in their blocks.
A transaction can only be considered secure and complete once it is included in a block. More confirmations are better for larger payments. Here is a visual so you have a better idea: 0 Payments with 0 confirmations can still be reversed! Wait for at least one. Most exchanges require 3 confirmations for deposits. Six is standard for most transactions to be considered secure. Chapter 3 How to Mine Bitcoins. Actually want to try mining bitcoins?
Most Bitcoin mining is done in large warehouses where there is cheap electricity. To be real: Most people should NOT mine bitcoins today. Most Bitcoin mining is specialized and the warehouses look something like this: Source ieee. Step 1: Get Bitcoin Wallet When earning bitcoins from mining, they go directly into a Bitcoin wallet.

Our mining profitability calculator will help you figure out if mining will be worth it.
Chapter 4 What is Bitcoin Mining Hardware. Bitcoin mining hardware ASICs are high specialized computers used to mine bitcoins. The ASIC industry has become complex and competitive.
Mining hardware is now only located where there is cheap electricity. However: Enterprising coders soon discovered they could get more hashing power from graphic cards and wrote mining software to allow this. Mining pools allow small miners to receive more frequent mining payouts. By joining with other miners in a group, a pool allows miners to find blocks more frequently. But, there are some problems with mining pools as we'll discuss.
Chapter 6 Inside the Bitcoin Mining Industry. The mining industry has come a long way since the early days of graphics card mining. What does a mining farm look like? Let's take a look inside a real Bitcoin mining farm in Washington state. Miner Anyone who mines Bitcoins or any other cryptocurrency. Block Reward The block reward is a fixed amount of Bitcoins that get rewarded to the miner or mining pool that finds a given block.
Mining Pool A collection of individual miners who 'pool' their efforts or hashing power together and share the blockreward. Block Reward Halving Approximately every 4 years, the block reward gets cut in half. Hashing Power or Hash Rate How many calculations hashes a miner can perform per second. You can learn more about Hash Rate by reading our article about it. Difficulty Measured in Trillions, mining difficulty refers to how hard it is to find a block.
Difficulty Adjustment Bitcoin was designed to produce block reliably every 10 minutes. Kilowatt Hour A measurement of energy consumption per hour. The media constantly says Bitcoin mining is a waste of electricity. But, there are some problems with their theories as we'll discuss. Certain orthodox economists have criticized mining as wasteful.
It must be kept in mind however that this electricity is expended on useful work: Enabling a monetary network worth billions and potentially trillions of dollars! Not just of electricity, but of money, time and human resources! Mining Difficulty If only 21 million Bitcoins will ever be created, why has the issuance of Bitcoin not accelerated with the rising power of mining hardware?
Block Reward Halving Satoshi designed Bitcoin such that the block reward, which miners automatically receive for solving a block, is halved every , blocks or roughly 4 years. Honest Miner Majority Secures the Network To successfully attack the Bitcoin network by creating blocks with a falsified transaction record, a dishonest miner would require the majority of mining power so as to maintain the longest chain. To achieve it, an attacker needs to own mining hardware than all other honest miners.
