the so called "taunt"(if i remember correctly) bitcoin, have their value reduced this was also a problem for the bitcoin fungibility
maybe for developed countries the reason for banning bitcoin for money laundering makes no sense, but for developing countries with very many criminals, especially corruptors who have very much money, of course the ban makes sense. because to limit their illicit money escape, countries try by all means to limit their illicit money movements one way by not legalizing bitcoin, because the state cannot detect or prevent criminals from saving their money ..
