According to the South Korean govt, North Korea makes quite a bit of money of crypto mining and hacking. If we could shut off there internet, we could make this income a lot harder to get and access, but it wouldn’t hurt the normal population like a blockade would. How hard would it be for China to support it? (I assume they provide the internet cables to NK). What are the negatives?
Also could this help slow the nuclear weapons program? I assume a lot of the uranium is bought from terror groups with crypto currency.
