It seems that if it is said that all countries are illegal, that is not entirely true, because we know countries like Vietnam, Japan, Singapore, have also legalized bitcoin as an alternative payment tool, not as a primary payment instrument.

But other countries may also have a lot of considerations that need to be studied more deeply about bitcoin, just as bitcoin is an easy thing for transactions in crime, why is that? because there is no data from the owner, and that will definitely be the biggest obstacle in a country to legalize bitcoin.
