Mining bitcoin package reward
bitcoin mining is a process that uses computer hardware to calculate the location of bitcoin and obtain it
mining is an incentive process to record data in the bitcoin system. In the bitcoin system, indivial users have the right to pack blocks after calculating a specific hash value by using CPU or GPU to hash
and in order to reward this user for packing blocks, the system will give a certain amount of bitcoin as reward. Because this process is very similar to "mining" in real life, most people call this process mining. In addition to bitcoin, other electronic virtual currencies can also be obtained through mining rewards, such as Ethereum, Monroe and so on
extended data:
mining risk:
1, currency security
the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin
2, system risk
system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income. However, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners
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
extended data:
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
2020 is the first year of digital currency proction rection. Most currencies will achieve the first proction rection this year, while bitcoin will usher in the third proction rection cycle. And the market is generally high on the halving market, it is expected that this year will usher in a wave of bull market, and the logic behind it is very clear. From the perspective of historical experience, this has already formed a more extensive "consensus" in the circle of cryptocurrency
secondly, bitcoin, known as "digital gold", is recognized by more and more funds for its risk aversion, which indirectly pushes up its price. At present, in addition to bitcoin, which has the most influence, BCH, BSV, etc, dash and other currencies are the most concerned. Dozens of counterfeit currencies have chosen to be halved in 2020. Therefore, 2020 is also known as the first year of halving
what is half bitcoin
bitcoin halving means that the reward for procing new blocks is halved about every four years. This means that after halving, the corresponding bitcoin reward for each block proced is only half of the reward before halving. At present, bitcoin has been halved twice, respectively in November 2012 and July 2016. The third half of bitcoin is expected to take place on May 13, 2020. By that time, bitcoin will be halved from 12.5 blocks to 6.25 blocks
half block reward means that it will take longer for all bitcoins to enter circulation, but it also means that mining will proce fewer and fewer new bitcoins. Moreover, e to its limited supply and increased mining difficulty, its scarcity attribute becomes more and more obvious, and scarcity will directly enhance the value. As the saying goes, scarcity is more expensive! For bitcoin, there is no doubt that this is a very big advantage
buying bitcoin in 2020 is better than buying bitcoin ETF fund
3, bitcoin current price 10000x4 = US $40000 (expected price after this year's proction rection)
in this period, the return comparison between holding spot and ETF fund is as follows:
1, buying spot holding, earning three times
2, buying ETF fund, Up to 15 times (intelligent position adjustment + fund compound interest calculation)
there is no doubt that bitcoin ETF launched by bitoffer is the best investment choice
a total of 2100W bitcoins are issued, and each block is generated for 10 minutes, and a block rewards a certain number of bitcoins. In the beginning, 50 bitcoins were awarded for each block of mining. In the future, the reward was halved for every 21000 blocks (about once every four years). Now, 12.5 bitcoins are awarded for each block generated. The generation time of each block is 10 minutes, but with the development of computer technology, now the mining calculation power is increasing, so the generation time of a block must be less than 10 minutes, which requires certain control measures to ensure this time. This measure is the difficulty of mining. If the output time of each block is less than 10 minutes, the difficulty of mining will be increased. If the output time is more than 10 minutes, the difficulty of mining will be reced. The difficulty adjustment time is 2016 blocks, that is, 2 weeks
after every 2016 blocks, all nodes will automatically adjust the mining difficulty according to a certain formula. This formula is obtained by comparing the latest time spent in 2016 blocks in this cycle with the expected time (20160 minutes, i.e. two weeks)
new difficulty = old difficulty * (time spent in the past 2016 blocks / 20160 minutes)
a block is a record in the block chain, which contains and confirms the transactions to be processed. On average, a new block containing transactions is added to the block chain by mining every 10 minutes
