Great question and topic.
Personally I think that kyc will not go away. And all exchanges will require it, those that dont will probably end up quitting by their own choice or by the government they choose to be in.
The US will probably make all exchanges require KYC when and where it can.
I mean binance doesnt server usa members unless they use a VPN to hide themselves, same as bittrex.
There are options like binance.us and bittrex us. But they dont see near the volume as the big players.
I personally dont mind the KYC. I know alot of people do and hate it.
I guess it can go both ways, but for me I do KYC.
