The UN has issued warnings against attending an upcoming cryptocurrency conference in North Korea, claiming that to do so would be in violation of sanctions against the Hermit Kingdom.Last year, Ethereum Foundation developer Virgil Griffith found out just how serious these warnings should be taken. He was charged with allegedly violating the International Emergency Economic Powers Act for attending the conference and giving an educational presentation on blockchain tech.To be honest, the US government may be right here. While we believe Virgil had nothing but good intentions, when you go to "teach blockchain and cryptocurrency" in a country where it's citizens are forbidden to use it - you're teaching the government and military.We hope everything is taken into account, and the US government realizes Virgil was blinded by passion for the tech, excited to be able to spread the word anywhere, and simply didn't evaluate the circumstances as much as he should have.This year's NK conference takes place Feb 22nd in Pyongyang.
