Isn't the Internet controlled by the government in North Korea? I wonder if they have access to Bitcoin over there?
If they are using VPN on their i think there was a little chance that it will be possible that they will have an access to the internet. If they know how to use it and create it as well. But i think if will that happen we cannot earn bitcoin anymore. It would be very hard for us that thing. But if we want we will make a way to that thing.
