Do you think governments are afraid legalizing bitcoin because it's difficult regulating its use, circulation, determining individual's worth, earnings and may lead to tax evasion?
I don't think so the government will getting afraid of legalizing the bitcoin in their local or states.
Bitcoin is not dangerous at all, infact they help to establish a well-organized society for everbody wherein all of us we will benefited from this. Bitcoin is such a wonderful blessing came from God that we should be thankful off.
