I do not think it will ever happen to bitcoin global regulation, because there will always be an incoherence between the rules of each state .. because bitcoin and crypto are the greatest opportunities for getting clappers, and that's what causes each country to have different rules about regulation bitcoin
Exactly, every country have their own belief about cryptocurrency but I think its good to have a global regulations so we can be more confident that they regulate cryptocurrency for the sake of both investors and a company. More countries will support this technology and I do hope G20 summit is the way to make that happen.
