I seen some big country started to legalized bitcoin like japan, but i seen some country was ban bitcoin too just like what i hear about south korean and issues about russian will ban bitcoin in next month.
But why they ban bitcoin and some country still not make bitcoin legal in that country ?
Bitcoin are still not legalized in some country because of the some matter. For example, people are too ignorant to see its potential in the future. They are afraid because of the fact that bitcoin is powerful and anonymous. Another factor is tradition and trade marks. It will be hard for some people to move forward and accept this change because they are more used to use the other currency. Another is government, the government know the potential of the bitcoins and it will affects the economy of the country. If bitcoin is discovered or known around the world it will be a problem to the government because some people might just mine or invest in bitcoin rather to work.
