Bitcoin mining difficulty increases 40% in one month

As the value of Bitcoin returns to $450/BTC (this wave of appreciation is believed to be related to the Chinese government's control over the flow of money), the difficulty of Bitcoin mining is also increasing rapidly.

According to the design of Bitcoin, the difficulty of mining will be adjusted according to the time required for the mined Bitcoin blocks (how long did it take to mine the 2016 blocks). Data shows that the difficulty of mining has increased by 41.9% in the past month.

     The reason is that the hash rate of mining machines has improved, and the time to mine a block is decreasing. BitFury, a Bitcoin mining machine chip manufacturer , has launched a 16-nanometer ASIC chip with a minimum computing power of 100 Gh/s, which can reach 140 Gh/s with air cooling and 184 Gh/s with immersion cooling. The company invested $100 million to build a 100MW mining data center. Currently, the hash rate of BitFury alone accounts for 28% of the entire network (200 Phash/s vs. 723 Phash/s).
