You missed Kyber Network:
https://kyber.network. Many people overlook this exchange. Maybe it's because of their poor marketing but Kyber is a solid DEX in which, Vitalik is an advisor. Its swapping feature is pretty clean and cool.
Actually, I knew it but I've never tried. So I don't want to share here what I don't know exactly.
DEx are too blocking US IP addressess. Binance DEX is blocking IPs from US and some other countries. Letting US citizens trade or buy coins had caused trouble for many ICOs and Exchange and they just want to stay away of that trouble.
Yes, but you can reach DEX with simple VPN apps.
I think this situation is very stupid. Why the government starts a war with everything that does not fully understand. In any case, decentralized exchanges are a really good alternative. In some ways, they are even better than centralized counterparts.
I think US government is about to release some regulations. Because of that, they want to control the market. (it is my opinion, there is no news) It is not cool! But fortunately, we have decentralized structure.
But we still need more decentralized APPs, platforms, projects... So globalization would be great then.
