Single miner mining
Now buy 120g mining machine, bitcoin at the current price, can do back to the original, it's very good. Bitcoin (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
expansion:
1. In 2013, the U.S. government recognized the legal status of bitcoin, which led to a sharp rise in the price of bitcoin. In China, on November 19, 2013, a bitcoin was equivalent to 6989 yuan. On January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. On February 26, 2014, Democratic Senator Joe Manchin of West Virginia issued an open letter to a number of regulatory authorities of the federal government of the United States, hoping that relevant institutions would pay attention to the status quo 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
2. On January 11, 2017, the Shanghai headquarters of the people's Bank of China and the Shanghai financial office carried out on-site inspection of bitcoin China, focusing on whether the enterprise carried out credit, payment, exchange and other related businesses without permission or license; Implementation of anti money laundering system; Fund security risks, etc. On January 12, 2017, the business management department of the people's Bank of China also entered the trading platforms such as "fire coin net" and "currency bank" in Beijing
1: the price of the miner is higher
2: we need to consider how long it will take to get back the original
3: it's troublesome to buy and troublesome to maintain
4: it is time-consuming and power consuming, and it also needs to run the mining software with the computer on
5: there are risks of depreciation and damage
the above risks and defects make many miners shy away from buying mining machines. Fortunately, we are in the era of cloud computing. Now the era of "cloud
miner" has finally come. Now there are websites selling computing power on the Internet. That is to say, they have a large number of mining machine cluster equipment and sell their computing power on the Internet, Generally speaking, cloud mining machine mining has the following advantages:
1: there is no saying that "you can't get back the cost". How much you dig is how much you earn. If you don't want to dig, you can sell GHS computing power at any time
2: there is professional mining equipment space to ensure the uninterrupted operation of mining machinery
3: no freight, no electricity, no depreciation, no risk of damage
4: computing power can be bought and sold at will, not limited to 1g, or only 0.001g. If you want to buy more, you can buy more, and you can sell if you don't want to
5: "cloud miner" digs bitcoin on the server side. You don't need to turn on the computer, just wait to receive bitcoin
now there are fewer and fewer bitcoins that can be g, and it is more and more difficult. If you want to dig bitcoin, you have to start early
although you don't have a graphics card worth thousands of yuan and a miner worth tens of thousands of yuan, you can be a hardworking bitcoin miner because of the cloud miner! Get a lot of money. Now I will take you to operate the happy process of mining with the cloud mining machine, because at present, the interface of the cloud mining machine is mostly in English, which is difficult for some beginners to understand. I will explain each detail carefully with pictures and text, and translate it into Chinese, please rest assured.
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
Every 100 S4 bitcoin mining machines consume 900W of electricity per hour
Babbitt has a bitcoin mining income analysis article, which has a figure for reference. According to its calculation, it's 132 days
is in an initial stage, but it's also an era of explosion, and everyone is participating in it. But really, whether it can be successful or not needs a big wave to wash the sand
