Bitcoin mining in 2012
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
Development:
1. Bitcoin (bitcoin) is a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar. In China, on November 19, 2013, a bitcoin was equivalent to 6989 yuan
2. On January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. West Virginia Democratic Senator Joe; On February 26, 2014, Joe Manchin issued an open letter to a number of regulatory authorities of the US federal government, hoping that relevant institutions would pay attention to the current situation of bitcoin encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency. On January 11, 2017), the Shanghai headquarters of the people's Bank of China and the Shanghai Municipal Finance Office carried out on-site inspection of bitcoin China.
to sum up, there are two simple points: first, the golden age of bitcoin mining has already passed, especially for indivials who are absent from work. It's hard to make up for the electricity charges of those who only have losses but no profits. Unless you have a unit dedicated computer for you to use, 24-hour power on non-stop digging. But this is still a loss, just unit for you to pay the cost, you take advantage of the unit
the second is configuration. Your configuration is too poor. Now mining is basically done with high-end a cards. It's necessary to connect several top graphics cards in parallel, such as 7970. You don't know how many generations behind. People don't necessarily earn money by digging with top-level cards, not to mention your one.
from 2010 to the beginning of 2012, few people knew about it, only some game players and geeks were playing it, and the number of domestic players began to increase in the second half of 2012. At that time, it was still the era of pyrograph card mining. At the beginning of 2013, the ASIC miner was born. Avalon delivered the world's first ASIC miner, and roasted cat issued the power stock
in April 2013, Avalon gave up the sales of the whole miner and opened up all miner design solutions except chip accidents. For a time, miner manufacturers emerged like spring training after rain
since August 2013, the positive reports of bitcoin in domestic media have been increasing, and the number of people who pay attention to bitcoin has also increased rapidly. The network index once reached more than 300000, and the price of bitcoin has been rising to about 8000 yuan. However, after the announcement of the central bank in December, the price of bitcoin began to fall all the way
in 2014, Avalon project developed a "variable computing power cluster system", and the price of bitcoin rose slowly in twists and turns.
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 />
It has been ten years since the birth of bitcoin, and the price of a single bitcoin has broken through the $40000 mark, which has attracted more and more people's attention. And the trend of bitcoin is more and more like a bubble. Strong>, however, in the short term, the bubble will not burst in the short term, and it will probably be cracked until the bitcoin is close to digging. Of course, the bubble will break up mainly depends on the capital of the speculation when what time to leave, if the capital does not leave the field, the bubble will continue to . p> According to the above two points, the rising price of bitcoin is more like the last craziness of bitcoin and the last means for capital to make money. Although it is not known how long this method will last, but because of the characteristics of bitcoin itself, it can not replace traditional currency as a means of daily life. , when people no longer recognize their value or do not need it, then the bubble of bitcoin will burst instantly. P>
generally, no one can accurately determine the time of bursting of bitcoin bubbles, because it is related to what time the bitcoin will be g and what time the capital will leave. p>
