2 Miner

1. This depends on what configuration of bitcoin mining machine you buy. Take Avalon mining machine as an example, avalon2
1t package (10 single-mode groups): the price is 13999 yuan; The price of avalon2 single-mode 100g is 1599 yuan; The price of Avalon 2-generation Miner 2 mole 200g is 2500 yuan. At present, Avalon three generation chips have been released, and Avalon 3 mining machine is about to enter the market.

2. Landlord, good, expensive. What's in bitland? It sells well all over the world< br />(*^__^*) Hee hee

3.

Mining needs high-end graphics card, mining equipment is the first to eliminate NV graphics card. Mining must be done with graphics cards. The overall structure of mining equipment and ordinary PC machine is different is the number of graphics cards. You can install four or eight through pic extension

after expansion, an expansion shelf needs to be made. To fix the graphics card and other equipment, we need to get some fans on the shelf to cool the graphics card

CPU is not very important. But not lower than i5< br />

4. Few people buy Avalon 2 single-mode group now, and the official does not necessarily have the goods. Now four generations of Avalon have come out. It's very difficult for the fourth generation to recover the cost of mining, not to mention the second generation. If you want to buy the fourth generation mining machine, you'd better buy it. Private letter me, I tell you<

now mining has approached or even exceeded the currency price, and retail Mining has graally withdrawn from the stage of history. However, if your electricity is free, it is still possible and profitable to buy mining machines. If the electricity charge is free, we suggest you buy the fourth generation miner or ant S5

5. This coin and that coin as far away as possible does not mean that it must be fake, the risk is too high

6. There is no official release schele.

7. Seventy or eighty sewing machines make a lot of noise. To tell you the truth, it's still very noisy. It's estimated that there are more than seventy or eighty decibels. You can make sure.

8. 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.

9. You can reprogram the little program in the official account.

10. 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.
