Two major US Bitcoin mining companies increase annual revenue by more than 300%.

"Distributed Storage China Tour and Open Source Mining Pool IPFS Private Meeting" sponsored by Open Source Mining Pool and Huobi and co-sponsored by Golden Computing Cloud, ChainUP and Filecoin Beijing will be held in Shenzhen on November 25, 2020. Kong Meng, Founder of VeryHash said during the meeting that the exchange rate fluctuates around the mid-market price. Whether it's PoS, PoW, or IPFS, the mining pattern should be an indicator of value. We are more concerned with which model has the best price. The most important support of PoW is the promotion of legacy in the market. The greatest support of PoS is by the currency value and the currency value is checked from the project side to a value of zero. IPFS is more difficult by default. Models such as deposit before and after releasing equipment prevent the cost in the short run but reduce water flow, but in the long run the rise and fall will cause other problems for the project.
