Guangzhou mining machine

1. It depends on the brand. Not every brand of Ethereum mining chassis has the same price. I have used the chassis of Shenzhen McKenzie brand, which is very good. I like it very much.

2. bitcoin is a kind of P2P digital currency. The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. 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 21 million.

3. This is last year's news: some netizens calculated a sum of money, and converted the computing power of tianhe-2 into mining efficiency. About two to three bitcoins can be g out in an hour, which is 15000 yuan. That's 360000 yuan a day. Mayor Chen Jianhua said that tianhe-2's daily electricity bill is 300000 yuan, which seems to make a little money. However, if labor costs, depreciation of machinery and other costs are taken into account, "mining" will not make much money

this is the data provided in a press release at the end of November last year. Of course, according to the current computing power, we can't dig so many bitcoins, and the revenue will be lower. Even tianhe-2 mining is a loss

after all, bitcoin mining is a professional business, it needs a professional bitcoin miner. And the update speed of bitcoin miner is amazing. Take the mainstream Avalon mining machine in the market as an example, it has been upgraded to three generations of chips, and the fourth generation will come out soon.

4. The most advanced bitcoin mining machine can only dig out a bitcoin in one or two years. Now it is more and more difficult to dig out bitcoin because its number is decreasing,

5.

In general, debugging is not easy to use, and there is no need to manage it. It's faster to get money. Now compare a hot project

6. Forehand excavators are generally used in the north, only backhand excavators are used in Guangdong. As long as you find a job in Guangdong digging machine, the boss is generally willing to adjust the backhand to forehand, which does not affect anything, as long as you have driving skills. When you apply for a job, you can ask your boss to change it to forehand, that is to say, you just need to adjust 4 oil pipes, it doesn't cost much.

7. Guangzhou Jinqiao school special worker driver training class. Learn a good technology and achieve a lifelong dream. Theoretical knowledge (5 days of training): 1, the role of excavators and the use of methods. 2. Learn the maintenance of excavator, the replacement of vulnerable parts and daily maintenance. 3.

9. To learn how to dig in Guangzhou,
find sister Wang at Fengshen Avenue, Hua
it's just opposite Dongfeng Nissan
if you study well, you can get employment
be able to practice on site.
