Yes some countries bitcoin is illegal,but in our country bitcoin is not totally banned but i think the government would implement rules on it inorder to avoid fraudility.This is due to the existing case done by a couple who started the pyramiding scam and has victimize innocent people.They invest in bitcoin without even knowing if it is legitimate or not.The couple got almost 1billion Phillippine money which had alarmed the government through the usage of bitcoin was used in illegal activities.They planned to put regulations on the usage of bitcoin,and in my opinion this idea is quietly right.
