Learned about Chia Coin, and... f*ck you miners.

I think putting too much compute power into a blockchain is a huge waste, there are lots of examples here. Blockchain is a good idea, but I think Consortium Blockchain has more (power) efficiency than public chain.

Nowadays GPU price has already blown my mind, now hard disk even be able to mining? My local seller shows that Samsung's EVO 970 Plus 1T has already increased 16% of its original price.

Public chain is a good idea, and can be used in a proper way, but since mining gives miner rewards, there are always some people want to earn coins mainly in this way, rather than normal use.

Blockchain might be a influential technology, but could those developers please try to leave along with regulars PC gears and turned to some specific hardware? Nvidia might have a right step(by limiting gaming cards hashing performance to prevent mining).
