How long can a home computer dig a bitcoin
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. In other words, the difficulty of digging bitcoin is increasing, while the time required is increasing
You can't dig in a day. It takes 2000 years
the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin
in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned

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
bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer
when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million
Recently, bitcoin has been swiping the screen frequently. One reason is that the story of "making rich" of bitcoin is surprising. The other reason is that the rise and fall of bitcoin is too crazy. After entering 2021, bitcoin is in a rising trend. Although it has declined ring this period, it has always remained at a high level
12 years ago, Nakamoto, a Japanese American, created bitcoin. It is said that Nakamoto himself has never appeared, but the bitcoin he created is crazy. This year, the value of bitcoin hit new highs, first US $30000, then US $40000. On February 22, 2021, the value of a single bitcoin hit a record high, reaching US $58000 each
is it sure to make money by investing so much money in "mining"? The answer may disappoint you again. Bitcoin's "wealth making" is based on the price rise. Once bitcoin's price falls and it is no longer so valuable, investors may lose all of it
some experts have warned that the bitcoin market is the easiest to be manipulated, because bitcoin is mainly concentrated in the hands of some people, and a virtual currency is so expensive that it can not be separated from the hype of these few people. At the same time, there is no sound and mature regulatory mechanism for the bitcoin market in the world, so the risk of investing in bitcoin is great
therefore, for ordinary people, it is better to stay away from bitcoin and "mining", don't you think
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
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

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
1. The calculation is mainly done by GPU, while the GPU of ordinary computers is not very powerful, which directly leads to the low efficiency of mining, and even the electricity bill can not be recovered
2. Because it is the exchange of data on the network, not only the performance of the computer should be good enough, but also the bandwidth and quality of the network should be higher. If you were asked to build a 100 megabit broadband of Telecom before, would you be so interested
3. GPU will generate a lot of heat ring calculation. If it is not handled properly or the original radiator is very dirty, it may burn the GPU or computer, and the gain will not be worth the loss
4. The other is the impact of the environment. Let's not say where bitcoin is going, but that the exchange rate is seriously declining and there is no money to be made before. Professional mines are even processing equipment. It's obviously unreasonable to go mining at this time.
bitcoin mining refers to the creation and addition of bitcoin blockchain in the process of block transaction. Each block contains hundreds of transactions, and each transaction is paid from one or more bitcoin addresses, other addresses or addresses
the process of creating blocks is called bitcoin mining because there are rewards for each new block to be created and added to the blockchain. In 2017, the reward was 12.5 bitcoin. So as long as you are faster than others and create a new block, you can get a 12.5 bitcoin reward
obviously, the speed of mining depends on the running speed and stability of the computer. Therefore, only professional "mining machine" can be competent for this job. This kind of machine configuration is very high, power consumption is very large, often need more than one cooperation.
After surpassing the peak in 2017 and breaking the $20000 mark, bitcoin has not stopped soaring. Bitstamp market shows that bitcoin has broken through the $34000 mark, a new record high
you know, as early as 2010, a programmer in the United States exchanged 10000 bitcoins for a $25 pizza. Now, a bitcoin has risen to a high price of 220000 yuan
Therefore, the author suggests that ordinary people who want to take the opportunity to invest should not invest too much. After all, bitcoin's sharp rise and fall is normal, so the investment risk is high, so we need to be cautious when entering the market
