Shanghai quantum mine

1. At present, bitcoin has not experienced an influential bifurcation. It's basically a worry about hard bifurcations. In the history of bitcoin, there have been many worries like hard bifurcations. For example, the computing power of a large mine has been close to 51% of that of the whole network many times; In addition, when ASIC mining machine was just born, people were worried about the huge mining computing power of mining machine manufacturers; People's concern about quantum computer's participation in mining is also long-standing; At present, the currency price is low, and mining is graally controlled by several large mines, which may also lead to the emergence of hard bifurcations; Recently, the hard fork crisis caused by bitcoin expansion has once again alerted people. But in fact, this is just a kind of worry, the probability of occurrence is very small

every time there is a hard bifurcation crisis, the currency price may plunge, which is mainly e to the worry of bitcoin.

2. yes , we have. Recommended ore pool for coin printing: https://www.poolin.com , the founder of btc.com, once founded btc.com, the world's first bitcoin mine

3. The mining machine of bitfish mine is a cluster mining machine with high computing power. The era of CPU mining has long passed, and GPU mining is not the mainstream. Now bitfish mine is an era of ASIC mining and large-scale cluster mining. Looking back on the mining history, bit mining has gone through the following five times: CPU mining, GPU mining, FPGA mining, ASIC mining, large-scale cluster mining, while the mining chips are updated, the mining speed changes are: CPU (20mbash / s), GPU (400mbash / s), FPGA (25ghash / s), ASIC (3.5tash / s), large-scale cluster mining (3.5tash / s * x), At present, bitfish is simulating quantum computing, but it is still a high computing power cluster miner.

4. It depends on what kind of entity you are. Many blockchain combined with entity instry can apply several characteristics of blockchain. Decentralization, traceability, openness, fairness, permanence, irreversibility and security can be used by instry. Blockchain + entity application development (e-micro) 138

5. Violation is on the edge of the legal boundary, just like the previous borrowing treasure and e-leasing treasure. Now the country is starting to crack down on bitcoin, which is also fast. At that time, many people will be caught, and the funds will not come back
