Crypto mining for beginners
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. 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. What You Need to Mine Bitcoins 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.
Mining hardware 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. An analogy 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: fcccfd95e27ce9fac56e4dfee 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.
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: ffff 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: Note: These are made-up hashes. 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. 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. A Pickaxe Strategy for Bitcoin Mining 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. Downsides of 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.
While in a PoW system, miners receive fragments of their mined block and transaction fees, in a PoS system, the users are rewarded through transaction fees solely. Running a node in a Proof of Stake environment requires you to have a minimum stake and a device. And for devices, generally, a laptop could handle the task, but the setting up may be troublesome, and running a node implies maintaining your uptime.
Also, some staking environments allow you to delegate your stake instead of running your own node. Which one is better? While the POW algorithm is generally considered a more secure system, PoS is a more scalable alternative with a better long-term plan. And considering the stake necessary to successfully attack the network, it might not even be worth it. Types of cryptocurrency mining Currently, there are 4 methods to mine cryptocurrency.
Cloud Mining Cloud mining is the easiest and perhaps the most efficient method of mining cryptocurrencies. You can rent a mining rig for an agreed-upon period through cloud mining and receive all the earnings of that specific rig minus the electricity and maintenance costs. In theory, this sounds like a great approach to mining. However, cloud mining is also one of the riskiest types of mining.
These companies would use the initial investment from new users to pay older users. After a while, all the payments towards the users would stop, and the company would go dark. While legit cloud mining services may exist, most professionals advise against using them.
When cryptocurrencies were a new concept, CPU mining used to be a viable and efficient solution. But right now, few people opt for CPU mining. First of all, CPU mining is extremely slow. It could take you several months to start earning a little revenue. And finally, CPU mining requires serious cooling, which adds another cost to the necessary investment. Not to mention that your CPU could get fried. GPU Mining GPU mining is by far the most popular method of mining cryptocurrency because it is both reliable and cheap er than the other methods.
GPU mining uses graphics cards to mine cryptocurrencies, and you can generally start with between 2 and 8 graphics cards. Additionally, you will need a CPU, a motherboard, a rig frame, and a cooling system. You can just buy a pre-built one. When compared to any other type of mining, ASICs are beasts. However, they are also highly controversial. ASIC mining rigs allow entrepreneurs to build massive mining farms at a relatively low cost, thus centralizing their operations.
This also allows them to generate massive profit margins and control, to some degree, the development of the cryptocurrency. A large enough mining farm would allow a single individual to generate the majority of the profits from a specific currency, thus making the whole mining process unfair. It is, essentially, just like a pay-to-win game. To combat this, developers plan to alter the codes of various cryptocurrencies to make ASIC miners less effective, while others plan to ban ASIC miners altogether.
Is cryptocurrency mining profitable? To successfully mine cryptocurrencies, you first need substantial computational resources. In the early days, Bitcoin mining was simple. All you needed was a laptop or a computer. Anyone could do it, but few people mined any coins since they held no real value.
But as block difficulty increased, the mining process became so resource-dependent that it required high-performance GPUs. Not long after, as the block difficulty kept increasing, the only way to profitably mine Bitcoin was with the help of ASICs miners. Of course, various cryptocurrencies can still be mined using simple computers. Some of them have even made it their mission to ban mining with ASICs equipment altogether.
But before deciding if mining cryptocurrency is worthy and profitable, you have to consider various aspects. If you were to ask most miners back in if Bitcoin mining is worth it, they would have probably said it is not. However, With BTC rising close to 60k and Eth over 3k while being on the highest transaction fees, mining cryptocurrency is quite profitable.
The prices are high, and the difficulty is just as high. The efficiency is a must because of the mining difficulty. Also, mining other newly launched cryptocurrencies can bring you some extra income, and the difficulty can be much lower. You can always use various online multicurrency calculators to determine the parameters involved, such as the hash rate.
The hash rate is the speed at which a cryptocurrency mining rig can solve the algorithm required to mine a new cryptocurrency block. If you decide that the operational costs are too high, but you still want to try your luck in the game, not all hope is lost. You can always join a mining pool and work together with other miners to mine blocks and share profits, of course. As a general rule, the profitability of the mining process is determined by four main components: Difficulty.
