Wouldn't it make sense for Kim Jong-un to open up a bitcoin exchange and issue a North Korean digital currency? It would be like btc-e only a hundred times bigger and with tons of margin options and currencies.
p.s. mtjong.com is available
Easy the population has no access to the internet.
The population is fed by the state.
The population gets clothes, housing, medical care and electric from the state.
Everyone works for the state.
Farmers give 70% of all food grown to the state.
N Korea is in the dark ages and have no clue as to what is happening in the world.
They don't drive cars, they walk, ride bikes and use the metro which is the deepest tunnels in the world and double as the best bomb shelters there are.
So the country has no public interaction to the internet and have no real money, they get a currency that has no value outside NK.
The few won they make is nothing and the population as a whole is malnourished and ignorant of what is going on in the rest of the world.
There's one TV channel in NK that plays non stop state propaganda all day.
North Korea and btc, or any digital currency will never, ever happen.
