How long does bitcoin need to dig
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.
Step 1: prepare mining machines and pools
if you want to dig bitcoin, you must prepare professional equipment. At present, there are many professional mining machines on the market, and the pool is also essential. When you choose a pool, you should also compare the output and income gap of each pool, and then choose the most suitable one
Step 2: register and set the mine account
after the mine is ready, register the mine account and set a common email. When setting the mine account, each CPU or GPU needs to set a mine account
Step 3: download the bitcoin miner
after you register and set up your account, you need to download the bitcoin miner. When downloading the miner, be sure to choose the miner that can make your CPU and graphics card play the most function. After downloading, set the server, user name, password, device and so on
Step 4: Mining
after setting up the miner, click the "start mining" button, the miner will enter the state of full speed operation, and the miner will start mining automatically.
-
it is estimated that 21 million pieces will be excavated in 2140

according to the relevant literature of bitcoin, in 2140, 2100 bitcoins will be proced and will not grow any more. According to the principle of bitcoin, after 33 halving periods, the mining output of each block will reach 0.58 Cong, less than the minimum unit of one Cong. The interval of each half rection is 210000 blocks, and the total proction time (2140 years) given in the above literature is calculated from the proction time of each block of 10 minutes 210000 * 10 / 60 / 24 / 365 = 3.9954 * 33 = 132 years. Since 2008, 132 years later, it is 2140 years)
however, the "proction time of each block is 10 minutes" used in the above calculation method is an ideal state, which is only true when the computing power and difficulty of the whole network do not change. Looking at the bitcoin blockchain, it is not difficult to find that bitcoin's whole network computing power has been growing for a long time, and the difficulty of mining has also increased. Therefore, it is not difficult to find out that the above calculation is not tenable and there is a huge error
the shortcomings of the above methods are that they can not accurately predict the change of bitcoin network computing power and the mining speed of bitcoin. The 11.3-day data used in the above calculation method is only the average value from May 2013 to April 5, 2014, and the representativeness is questionable. We can integrate the results of big data analysis and mining machine proction to establish a more accurate mathematical model
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
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.
