I dug bitcoin for a year
CPU mining → GPU mining → FPGA mining → ASIC mining → large-scale cluster mining
while mining chips are updated, The change of mining speed is:
CPU (20mhash / s) → GPU (400mhash / s) → FPGA (25ghash / s) → ASIC (3.5thash / s) → large scale cluster mining (3.5thash / s * x)
mining speed, which is called computing power in professional terms, is the ability of computer to generate hash collisions per second. In other words, how many hash collisions can our miner do per second is the calculation force. Computing power is the ability to dig bitcoin. The higher the computing power, the more bitcoin you dig, the higher the return
in the world of bitcoin, a data block is recorded about every 10 minutes. All mining computers are trying to package the data block and submit it, and the person who successfully generates the data block will get a bitcoin reward. Initially, bitcoin rewards of 50 bitcoins could be generated about every 10 minutes. But the payment is halved every four years, and now the bitcoin network can generate 25 bitcoins every 10 minutes
in order to successfully generate data blocks, miners need to find the effective hash value. To get the correct hash value, there is no shortcut. They have to guess. The process of guessing is the process of computer random hash collision. If you guess correctly, you will get bitcoin
so far, the highest 1btc price in bitcoin history is about $20000, with a market value of more than $60 billion.
Bitcoin is a kind of network virtual currency. Bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system. Assuming that the mining computing power is 100 mhash / s and the total computing power is 4000 ghash / s per day, 3600 bitcoins can be g out every 24 hours
China's computing power has accounted for more than 75% of the world, that is to say, 75% of bitcoin in the world is made in China. How long does it take to dig a bitcoin
bitcoin used to be very good at "digging", which can be done by ordinary computer CPU, and it can automatically "solve problems" by downloading software. But with the rise of currency price, more and more people want to "solve the problem", and the difficulty of mining is also increasing. Now, the amount of computation needed to dig a bitcoin is beyond the reach of ordinary people. Ordinary computers can't afford it
instry insiders said that in 2014, 100 bitcoins were generated from 500000 yuan of electricity charge per day, and the cost of electricity charge alone was 5000 yuan per coin. But now, the same cost has more than doubled, and the electricity cost of each bitcoin is as high as 10000 yuan
in the generation mechanism of bitcoin, mining reward is decreasing. At the beginning of the birth of bitcoin, the miners could get 50 bitcoins for each page of the ledger, and then 25 bitcoins for each page of the ledger, decreasing in turn. It's like digging gold. At first, it's more and less. The time point at which each new reward is reced by half is called half bitcoin proction
assuming that the mining computing power is 100 mhash / s, the total computing power is 4000 ghash / s per day in 2014, and 3600 bitcoins are g out every 24 hours
now, we can understand the difficulty of bitcoin digging in this way, which is equivalent to 100 million dice throwing numbers less than 100 million and 50 million. Whoever throws them first will get the bookkeeping right. At this point, 1050 million is a hash value. The process of throwing dice is called hash collision. The unit of mining power is the number of hash collisions per second
at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements
in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million

this depends on the CPU computing time of your computer, and on your network speed. If you use an ordinary home computer or a personal mobile phone. You don't have to get a bitcoin a year
unless there are more powerful mining machines. Of course, it will cost more. Unless you don't invest in mining machines, you invest in illegal software. Let these illegal software invade other people's computers and mobile phones. Other people's computers and mobile phones do a lot of bitcoin computing and mining. In this way, the cost of mining machine, electricity, flow, heat dissipation and so on are saved. But we need to know that this is a violation of national laws. This will also allow other people's mobile phones to carry out a lot of calculations after power on, encroach on other people's memory, and make other people's mobile phones scrapped earlier< br />
At present, if the computer is on 24 hours, it will take about three months to dig a bitcoin. In other words, a computer can dig up to a third of bitcoin a month
bitcoin is the most popular virtual internet currency in the world, and it can also buy a lot of things now. This kind of virtual currency can be obtained through the function of mining machine
first of all, your computer should have installed the latest version of bitcoin client. After opening the client, it will automatically download all the transaction information data on the network to the local. According to the different network speeds, this process may take several hours. At this time, your account balance is 0, you can let friends send some money, but there are two more feasible ways: one is to do business, the other is to do mining. Many domestic users choose the second way, that is to do mining. More and more people are willing to work as miners themselves and let their computers proce bitcoin! It sounds tempting - just one computer can make money! The bitcoin g up by yourself as a miner can be converted into real RMB at bitcoin China trading platform
now the threshold is higher than before. It's better to need professional computers. The difficulty of bitcoin mining is directly proportional to the amount of money that has been mined. The more difficult it is to mine, the more difficult it will be. After 20 million bitcoins are mined out in 2030, the remaining 1 million bitcoins will probably take decades to be mined out. At present, if the computer is on 24 hours, it will take about three months to dig a bitcoin
If you don't manually pick up the coins you dig in the mine, you will automatically send them to your wallet when they accumulate to 1. Of course, you can set how much you want to pay automatically. Just set the receiving address of your wallet in the mine. It's just that we can't dig BTC and use computers now. Even the electricity bill is not enough. There is a special ASIC to dig
first of all, bitcoin is not created one by one. Bitcoin is made up of one account book after another. As long as you can record one account book, the system will reward you accordingly (starting from 2009, after four years, one will reward 50 bitcoins, another four years, one will reward 25 bitcoins, and so on), Because the account book records the transaction information, the transaction fees generated by the transaction also belong to the bookkeeper. Such a good thing, of course, everyone wants to keep accounts. At this time, the more wonderful thing will come. The system will put a mathematical problem every ten minutes. Whoever works out first will have the right to keep accounts. They can keep accounts and get bitcoin generated by keeping accounts
then the generated bitcoin will be saved in your wallet address. You can transfer the bitcoin in the address to EXX. There are not only bitcoin, but also more valuable currencies. Of course, you need to choose
investment is risky, and we should cherish it
According to the current computing power of the whole network, it takes 54436.5t of computing power to dig a bitcoin 24 hours, that is, one bitcoin a day< it requires 746 mining machines with the latest 73t capacity on the market to work together for 24 hours
the cost of mining mainly includes (mining machine cost / power cost). Now the latest miner is 22650 yuan, a miner consumes 77 kwh per day. At present, the price of mining machinery on the market is about 0.36 yuan, 28 yuan per day. The cost of mining bitcoin = mining machine price (22650)
mining bitcoin requires a professional site "mine" to place mining machines. The construction cost of placing about 3000 mining machines in a small professional mine is about 300 watts
extended data
unable to mine at home
the noise of 60-80 decibels will be proced by the mining machine in the working process. Mining at home is not feasible, the miner needs 24 hours of endless operation, so the temperature of the miner will be very high, the maximum temperature can reach 80 degrees. Therefore, mining needs a good environment to rece the temperature. Household electricity and electricity charges are high, and the cost is higher than the income. In addition, mining has a certain degree of professionalism, professionals need to carry out certain operation and maintenance to ensure the normal operation of the mining machine
the key to rece the mining cost is to purchase mining machines in batches and low electricity charges. Professional mine is built to ensure the operation of mining machinery. At present, the mainstream mining machinery manufacturers are bitcontinental Technology Co., Ltd. in Beijing and Jianan Yun Technology Co., Ltd. in Hangzhou. Mining machinery is proced in the form of appointment in futures. It is difficult for indivials to buy Mining machinery in small quantities on the official website. After years of development, the mining machinery market has formed a complete instrial chain. The price of mining machinery fluctuates with the price of money, and the power resources are basically distributed in the cheap western region. Getting cheap electricity prices requires personal resource advantages
you are not well informed.
the total number of bitcoins is 21 million. As of January 13, 2018, 16.8 million bitcoins have been mined in the world, with 20% left, that is, 4.2 million bitcoins are waiting for everyone to excavate, facing the situation of "more than enough"
in November 2012, the new issue speed of bitcoin was reced to 25 bitcoins per block
bitcoin mining relies on the use of computer chips to calculate specific encryption algorithms. With the increasing scarcity of remaining bitcoin resources, the mining cost of a single bitcoin is also increasing. As the Chinese government has taken strict measures to restrict mining, the winning rate of indivial mining may be a little high, which is normal. But at present, SEO in China has been limited. The risk is enormous.
