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. Except still not get allowed regulating about bitcoin as legal currency transaction payment but government controlling about bitcoin so far seem good opportunity. Need waiting few years later to see regulating about cryptocurrency and become legal payment currency at the future, but if government have open minds and allow as investment way I think enough reason without expected one day later bitcoin become legal currency transaction.
