What is supposed to mean, maybe they would adopt it but it is already hot in Korea. I would see a lot of people cry, because bitcoin already so high and no one expected to go higher.
well uh it mean that you can use bitcoin as a currency like in japan, which is huge because it open the door, for more adoption, everyone would try bitcoin now without fear their government
in fact it was never illegal to beign with, it was not regulated, currently bitcoin is illegal only in few country like bangladesh, all the other just need to regulate
