Maybe in the next few years will be legal. Given the increasing bitcoin users and also the practical bitcoin to do the transaction plus the other features that make it easier for bitcoin users
maybe the use of bitcoin has been very broad and some countries have recognized and used it for legitimate exchange tools, but there are still many countries that still reject the use of bitcoin, especially poor countries and underdeveloped countries, and there are still many areas that have not been touched by sophisticated technology and purchasing systems and their sales are still traditional and still use conventional currencies
I think the use of bitcoin is only limited to developed countries, for developing countries it is likely that it still takes a long time.
