Open pit digger
The most advanced bitcoin mining machine, one to two years to dig out a bitcoin, bitcoin mining is now too difficult. If you want to dig, you can dig ether currency. Now it is steadily appreciating every day. According to the current development trend, it will be able to recover its capital in about seven months, and then it will be profitable< br />
Every 100 S4 bitcoin mining machines consume 900W of electricity per hour
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 />
As of July 24, 2020, the state has not issued any laws to prove that bitcoin mining machine is illegal
bitcoin mining machine is one of the ways to obtain bitcoin. Bitcoin is a kind of network virtual currency proced by open source P2P software
it doesn't rely on the issuance of specific monetary institutions, and it is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
extended data
the issue and transaction of bitcoin are realized by mining, and it is cast at a certain but slowing rate. Each new block is accompanied by a certain number of new bitcoin from scratch, which is used as a coinbase transaction to reward the miners who find the block
the reward for each block is not fixed. For every 210000 blocks mined, it takes about four years, and the currency issuance rate is reced by 50%. In the first four years of bitcoin's operation, each block created 50 new bitcoins. Each block creates 12.5 new bitcoins. In addition to the block award, the miner will receive a handling fee for all transactions within the block<

From the perspective of equipment level, China's open-pit mine equipment can be roughly divided into three types:
(1) small mine equipment is single, small and not matching; Some processes are still manual labor
(2) medium and indivial large mines have a high degree of mechanization, but the equipment is old and backward, and the efficiency is not high
(3) a few large-scale mines use imported or domestic modern equipment, such as rotary drill, electric wheel truck, large capacity excavator, high-power bulldozer, etc., to form a complete set of operation line, which has high efficiency
