There are already regulations that are the legal basis for trading cryptocurrency assets as one of the tradable commodities.
The regulation certainly can stimulate the interest of the Indonesian people to accept and develop cryptocurrency, certainty and legal protection and also regulate the provisions on anti-money laundering and the prevention of funding of terrorism. This will certainly make Indonesia a cryptocurrency center in Southeast Asia.
