That's the weakness of KYC and we had a taste of it when facebook got hacked and another one when this forum's database got stolen. I miss the times when we could trade freely without having to deal with KYC on sites like bittrex and poloniex, but things change. Unfortunately, in most cases they change for the worse.
I used to be and still am against KYC and government agencies trying to oversee crypto trading, but reading the posts of some forum members here makes me thing that I'm in the minority.
