Actually, Bitcoin is not yet fully legal, but some countries have made it legal. In the case of Bitcoin discussion every day it is becoming popular. And the day is not too far when Bitcoin is completely legal. As all of us knows it is, the king of all coins and through this can make life even better.
legal or not, this will not be a problem in trading, as long as bitcoin does not violate the law, so we are still free to trade bitcoin over an internet connection, because on the internet there will be no borders, so that usually makes it a problem if we exchange bitcoin, and we transfer into a local bank this can be a problem, because usually a large amount raises the suspicion of law enforcement.
