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 ?
I think the one reason why the bitcoin was not legalise and banned in some country is because of using in illegal transaction. Bitcoin is popular now and very beneficial on some user because it is source of income but it can also used in illegal doing. By hiding their identity of the user is hard to detect by the law who used this in illegal doing. Additionally those countries who not legalise the bitcoin has a demand currency which will affect the economy of the countries by competing their currency.
