Li Qiwei supports PoW, suggesting that PoS is defective

Litecoin founder Li Qiwei recently shared his mining experience in an interview. He said he created a GPU mining machine to mine bitcoin. This GPU generates a lot of noise and generates a lot of heat. But he did not get any bitcoin from it. At the same time, the difficulty of BTC has soared, and the GPU is no longer useful for mining. In addition, for some people think that the proof of work (PoW) is unfair, because mining compensation will continue to decrease, Li Qiwei said that he believes mining and work proof may be the fairest way we can do.
