first of all op's question is totally different from your answer, op is asking why bitcoin is still not legalized on most countries and that simply means he only wants to know the reason of this , he doesnt want to hear how great bitcoin was in your country philippines or any of these central banks of the philiipines blah blah blah. anyways @op i think the main reason why some countries wont accept and legalized bitcoin is because bitcoin is just only a digital currencies and other factors i think is that they sees bitcoin as a rival or threat to their company for example banks because people tends to invest more in bitcoin due to the fact that they can earn more interest on it instead of banks.
