Home computer 24-hour mining
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
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
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
web link post bar example:
we will calculate the graphics card to dig bitcoin earnings
assuming you are HD 7950 awesome, according to Zhongguancun online information, approximately 500MHashs/s
HD 7950 is g to compare the power of the graphics card, calculate 500MHashs/s, converted to 0.5GH/s. I am your current graphics card, you don't need to buy it
the full load power consumption of HD 7950 is 210W, the graphics card mining is full load work, and the electricity charge is 0.6 yuan / kWh
I reckon that you have been digging for 180 days in a row, that is, half a year, 24-hour power on. You should pray that your computer will not hang up because of this
difficulty coefficient: the difficulty of bitcoin has been increasing. Generally, the calculation is increased by 30% in 11 days. I'm a little less. It is increased by 25% in 11 days
OK, all the parameters are ready, calculation
in calculation...
eh, how come it's a negative number
because you need to pay the electricity bill for your graphics card
and there is no bitcoin output every day, because your computing power is too low
suppose your graphics card is HD 7950 and the computing power is 0.5gh/s
at present, 200g ASIC mining machine is on the verge of elimination, because 3T mining machine is already looming in the market
but even the 200 g miner that is going to be eliminated is 4000 times of the 0.5 calculation power of your HD 7950
Bitcoin is illegal in China
since September 4, 2017, China has expressed its opposition to the virtual currency exchange. On the market, large-scale exchanges are graally fading out of the domestic market. Some of them are going to Japan and some of them are going to Nanyang. Of course, with the release of new regulations in Hong Kong in early November, we believe that in the future, the virtual currency exchange may obtain a legal license in Hong Kong to serve local institutional investors
extended information:
bitcoin China said that the platform will stop withdrawing cash. So far, bitcoin China has closed all transaction functions. The other two bitcoin trading platforms in China, huocoin.com and okcoin, have also stopped trading all digital assets against RMB
the virtual currency represented by bitcoin has soared, attracting a large number of ordinary people without any technology and investment knowledge to enter this high-risk market
the central bank, together with many ministries and commissions, issued the announcement on preventing the financing risks of token issuance (hereinafter referred to as the announcement), which pointed out that no organization or indivial may engage in the financing activities of token issuance illegally According to the announcement, all kinds of token issuance and financing activities should be stopped immediately from the date of issue
the organizations and indivials that have completed the token issuance financing should make arrangements such as liquidation, reasonably protect the rights and interests of investors, and properly handle the risks. Relevant departments will seriously investigate and deal with the activities of token issuance and financing that refuse to stop and the illegal behaviors in completed token issuance and financing projects
the China Internet Finance Association issued the "tips on preventing the risks of bitcoin and other so-called" virtual currency ", pointing out that bitcoin trading platform is a tool for money laundering, drug trafficking, smuggling, illegal fund-raising and other illegal criminal activities e to the expanding number of stakeholders and strong speculative atmosphere; There is no legal basis for the establishment of various so-called "currency" trading platforms in China
