When will M-chain entity miner come out

1.

It is reported that the performance of bm1385 chip is more than twice that of bm1384

The power supply scheme of S7 is similar to that of S5. The S5 + mode of dense chip arrangement is adopted, which makes the arrangement structure more compact. Under the same space, 60 chips are placed in S5 and 162 chips are placed in S7

The price of S7 is 1823 US dollars, equivalent to 11650 RMB yuan, and the delivery time is from September 21 to September 30. At the same time, the official announced the parameters of ant mining machine S7. The chip adopts bm1385, a 28nm fully customized chip independently developed by bitcontinental, with a computing power of 4.86t and a power consumption of 1201w. Ant miner S7 is the best miner with the best power consumption ratio so far, and the power per T is about 250W

official website is not open for sale at the moment. Users of early adopters can place their orders in overseas official website. The delivery address is 17% of the Chinese mainland tax and the purchase price is 13630 yuan. p>

ant mining machine S7 specification parameters:

bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan

bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce

bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high

3. Cash can be withdrawn every day and returned in five months.

4. Play off cloud, I bought before is 399, now seems to be 100 yuan, in JD, hope to adopt

5. Physical mining machine is just a cover up, in essence, it is network pyramid selling.

6. 4m
according to the current output, the global output is only 3600 bitcoins per day. Even if there are 1 million machines in the world, the average number of machines per year is only 1.3! Don't talk about making money. I don't know if I can get back to the capital only after a long time. The real money makers are those who sell mining machines. Let's stop now, it's still time

7. In fact, bitcoin mining can not blindly pursue the size of computing power, but also depends on the overall performance of the miner. For example, the single-mode group of Avalon mining machine 2 will be able to recover its cost in about 40 days, but the 800g recovery time of Avalon mining machine 3 is far away, unless the currency price rises. If you are a retail investor, it is suggested that you buy mining machines with small calculation power and fast cost recovery time, which should be regarded as playing. If you have abundant funds and the ability to set up large-scale mining plants, it is suggested that you buy mining machines with high calculation power and high profits. Avalon's 2.3t miner is said to be coming soon.

8. Er, it's troublesome to give a full and accurate answer. It's easy to say that if you look at the dialogue before you open the fight, you will probably know that boss is a high defense player, just use the pure high flash player, just use the pure cooperation without losing the critical hit, high attack first, pile up defense support, and use the proportional kill skill in the first round when the HP is high
