Fuck China, we should ban them from DeepOnion
That's the spirit!
also there will be decentralized exchanges
Yes, but decentralized exchanges are only useful for crypto <-> crypto trading. As far as I know, there's no decentralized exchange that could do crypto <-> fiat. So my point still stands. In all that fight for decentralization and against control and oversight of "trusted" third parties such as central banks or governments, the flow of money between crypto and fiat is our most vulnerable spot.
also existing exchanges can move to another country
True but unfortunately this is only cat and mouse game. It would be really awesome, if someone could come up more permanent and definitive solution.
