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 ?
Some Government are just seeing stuffs others do not. The countries that banned Bitcoin in their sovereignty saw something that might affect their economy as a whole if they keep on accepting Bitcoin. Others still continue to support Bitcoin because they benefit from it. Those might be the simplest reason for this type of scenario. Though we cannot know for certain what the real reason is.
