All countries have regulating about cryptocurrency exactly with exchange market account due need pass KYC process for withdrawing, except with several countries regulated about which one available coins for listing on the market or not.
You're wrong, NOT all. Not all countries have concerns about crypto and some of them never mind about it and just let their people do buy and sell. It was just the exchanges themselves asking for KYC, not because they are pushed by the government (maybe in some areas). Maybe we could see all of the countries will impose those regulations but for now, it was just a few to have the urge to do this because they found out that this was used for criminal activities like money laundering and fraud.
