Shhh they told them they were hackers, they're really just mining the bitcoin like normal
The hacker's reward? A bowl of rice for each bitcoin
These guys have played Command & Conquer Zero Hour.
How the fuck did they get hackers? They've got one damned modem
Wait north korea has hackers? A country with very limited Internet access is able to train hackers of skill enough to hack into cryptocurrency exchanges. Exchanges that deal with online currency that must have insane security measures? Wtf? How does this make any sense
Edit: thanks for the informative replies, for those of you who are too lazy to google like me; it basically comes down to money. Using that money to hire/train hackers then use them for whatever you want.
