How much does a bitcoin mining machine earn every day?
Many people are asking me how much money can be earned by mining a bitcoin mining machine every day?_DJMINER
This article is to clarify this issue for everyone.
The Bitcoin system itself is composed of one data block, and each data block has two parts: the block header and the block body. Among them, the block header records the block ordinal number, the hash value of the previous block and the block, the time stamp, the mining random number, the mining difficulty information; the block body, the pure record transfer and transaction information.
Each data block is linked by its block header information and its neighboring blocks, and is called a "blockchain". The illustration is as follows.
The information for each transaction is about 500 bytes, and the bitcoin block size is set to 1M, which can record about 2,000 transactions - in contrast, the size of the block header is only 80 bytes.
The Bitcoin miner, which packs about 2,000 transactions into a data block and adds it to the Bitcoin system. The first miner who successfully added the block (which will be broadcast to the whole system via P2P) will get out. Block rewards.
At the beginning of the birth of Bitcoin, the block reward was set to 50 bitcoins/blocks. When the number of blocks reached an integral multiple of 210,000, the block reward was halved. At present, the bitcoin miners’ bonus is 12.5. Bitcoin will become 6.25 next year. In this way, it has been halved until the smallest unit of a bitcoin "Cong" can not be produced (1BTC = 100 million Cong), at this time the block reward will stop - estimated, this will probably happen in 2140 (Experienced halving 32 times).
You should have heard that Bitcoin rewards are halved every four years – this is because people calculate a block every 10 minutes and the time required to dig up 210,000 blocks is 3.995, which is almost 4 years. .
What needs to be clarified is that the bonus of the miner also contains two parts: the current 12.5 bitcoin is a block reward, which is called “system reward”; there is also a billing fee, also known as “ Miners' fees, the current miner fee for each block is about 0.1 bitcoin, so every time a miner excavates a block, the actual gain is about 12.6 bitcoins._DJMINER
The Bitcoin system is set to dig up a data block every 10 minutes and add it to the chain. Counting 144 new blocks per day (24 hours, 1440 minutes), the total number of bitcoins that can be dug every day is 1800 pieces (144*12.5), plus miners' billing fees of 0.1 bitcoin per block. At the current stage, all miners receive a reward of 1814.4 bitcoins a day.
In this way, is it easy to understand Bitcoin mining?
The problem with mining is that many miners have packaged transaction information at a certain stage. Which miner is recognized? To solve this problem, the Bitcoin system gave a puzzle. Whoever solves the answer to this puzzle first recognizes which miner.
The so-called problem-solving process is the hash operation. Hash operation is a professional cryptography problem. It is not explained in detail here. You only need to know the ability of hash operation to solve problems and how much time can be done in computer unit time. Related to the secondary operation._DJMINER
It is precisely because of the process of hashing that it is to provide more riddles to hit the big luck, just like looking for gold in the massive sand, so the bookkeeping process of Bitcoin is called "mining."
How many times a mining machine can perform hash operations per second, which is the most important measure in bitcoin mining - computational power, usually recorded as Hash / s, abbreviated as H / s, the following arithmetic unit Is the geometric magnitude of H/s.
1 KH/s = 1000 H/s
1 MH/s = 1000 KH/s
1 GH/s = 1000 MH/s
1 TH/s = 1000 GH/s
1 PH/s = 1000 TH/s
1 EH/s = 1000 PH/s
From 1H/s to 1EH/s, the distance is 10 to the 18th power, and the average computer we use every day is about 1KH/s.
It is the operation of Bitcoin's entire network that generates 1,800 new bitcoins per day, which is directly related to the revenue of mining.
Since the birth of Bitcoin, from the CPU mining of ordinary computers, to the GPU mining of graphics cards, to the mining of FGPA (Field Programmable Gate Array), to the current ASIC (Application Specific Integrated Circuit) mining, bitcoin mining machine Already undergoing 4 iterations, the computing power of mining bitcoin has also grown from small to large, driving the development and improvement of the Bitcoin system._DJMINER
It is conceivable that if the puzzles are all the same, then as the market's computing power increases, the bitcoin block output will definitely get faster and faster. In order to ensure that the bitcoin block time is kept at around 10 minutes, after every bit of the 2016 block is dug, the bitcoin system will adjust the difficulty of the puzzle according to the calculation of the bitcoin network in the previous stage. A block is out in 10 minutes, and the 2016 block is almost two weeks.
If the mining power of one cycle of the system increases, the difficulty factor will increase;
If the mining power of a cycle on the system is reduced, the difficulty factor will drop...
Of course, the greater the difficulty, the same amount of computing power, the smaller the bitcoin gain.
- Ah,
To make money, not only must consider the issue of income, but also consider the input, including the cost of mining machine, the calculation of mining machine, power consumption, electricity and operating costs.
Give a chestnut to illustrate:
Suppose you get a mining machine with a computing power of 16TH/s and a power consumption of 1280w. The electricity cost is 0.4¥/kWh. The current net computing power of Bitcoin is about 66EH/s. The bitcoin price is currently ¥¥. Calculate 70000/piece, let the machine sleep 24 hours without sleep, how much can you earn in one day?_DJMINER
The gains from daily mining are calculated as follows:
1814.4 (bitcoin is produced every day) *70000 (coin price) *16/66000000 (the ratio of your computing power to the total network computing power).
Calculated, this figure is about RMB 30.8. This is the income of your daily mining. If you cut out your electricity cost: 24*1.28*0.4=12.3, the net income per day is about 18.5 yuan.
The example just listed is the calculation power and power consumption of the most popular ant mining machine S9SE-16T mining machine manufacturer. The current market price of this mining machine is about 4,000 yuan - assuming the currency price remains unchanged. The electricity fee will remain unchanged, and the bitcoin will remain unchanged. The purchase of an ant S9SE-16T mining machine will take 216 days to return to the original, regardless of other operating costs.
If you want to know the current daily profit of the mining machine with different power and power consumption and the possible return period, you can click “Read the original” in the lower left corner of the article to calculate.
Of course, the price of mining machines is changing at any time, and the price of bitcoin is highly volatile. Therefore, the daily income of Bitcoin miners is actually very uncertain.
In any case, as long as the currency price remains the same, now you can buy a mining machine and you will not lose it?
of course not!
——Because the current mining revenue is good, in the case of Bitcoin’s total network computing power, the more and more computing power is joining the mining army, and the computing power of the whole network is still growing rapidly (see above). Figure) If the computing power increases to a certain amount, it will lead to a significant increase in the difficulty factor, and the daily mining revenue will be greatly reduced, not even enough to pay the electricity cost.
At the end of 2018, because the price of Bitcoin fell 80% compared with the high point, and the computing power of the whole network was at a high level. At that time, the mine owner who bought the mining machine at a high price had the situation that the mining revenue did not meet the electricity bill. There has been news of "the mining machine is selling"._DJMINER
I estimate that the vast majority of ordinary people are more concerned about another problem -
Can I dig into Bitcoin with a normal computer?
The answer is: basically impossible.
In the early days of bitcoin development, the computing power involved in mining was very small, and ordinary computer CPUs could still dig into bitcoin. However, after 2011, personal computer mining could not meet the electricity bill and machine loss, and began to use video cards. Mining, but with the continuous increase in the computing power of the whole network, there is no point in the mining of graphics cards. Nowadays, ASIC (Application Specific Integrated Circuit) mining is widely used, and other mining methods can not cover the cost.
As I said before, the computing power of an ordinary computer is about 1000H/s, and an average of 1000 hash operations per second can be performed. The current computing power of Bitcoin is as high as 66EH/s, and the computing power of an ordinary computer is equivalent. The Bitcoin system has a total power of 66 trillion, and the Bitcoin block produces 52.56 million a year. You use a common computer to mine for one year, and the probability of generating a bitcoin block is less than 1 trillion. One of the points, this is almost the same as the probability of your second consecutive Lotto jackpot.
This has not calculated your electricity bill and computer loss...
However, after reading the example of mining that I wrote earlier to make money and return to less than a year, some people have to be heart-warming. I said that I bought an ASIC mining machine and put mine in my home. Regardless of the situation, talking to people is also a "family with mine" fan!_DJMINER
I advise you not to think so.
Not to mention the problems of noise pollution and huge power consumption, we say block rewards. We said earlier that it is to excavate the block to reward 12.5 bitcoins, and the miners’ yarns that can’t be dug are not. The mining machine with a force of 16TH/s is less than 4 millionth of the total power, which means that the probability of you dig out a block in one day is less than 1 in 4 million, which is very close to zero.
In other words, if you really bought a 16T mining machine to mine at home, let alone earn 18.5 yuan a day, you have a probability of more than 99.9999% every day to get the electricity and mining machine loss and get nothing, this is exactly the bit The reason why the "mineral pool" prevails in the coin mining circle - the so-called "mine pool" is a platform that concentrates on the calculation of many miners, so that the probability of digging the block is greatly improved, and then the area that has been dug Block rewards are distributed to miners in accordance with agreed rules.
Of course, some people are "having perseverance", not afraid of trouble, and don't worry about wasting money. If you want to try the probability of 1/4 million, then I have to resolutely encourage it. After all, this is a rare not for myself. For the dedication of others, there is one more independent mining machine, which is to contribute to the decentralized system of Bitcoin!
What's more, it is not easy to live 4 million days. From the appearance of the text to the present, the history of human civilization is 2 million days in total._DJMINER
