There is no official public law, central-bank decree, or regulatory ban on cryptocurrency or Monero in North Korea. However, for ordinary citizens, crypto ownership or use is de facto completely illegal and extremely dangerous (punishable under the regime’s total control over foreign currency, internet access, and capital). The North Korean f***g state, on the other hand, actively uses cryptocurrencies including Monero🙃
TL;DR in a totalitarian regime where you can kill ppl as you wish w/o any reason or due process you do not need "laws"
