I'm not surprised.
The Sth Korean and Japanese governments are puppets of DC.
Wall Street banks have the most to lose if crypto's supersede fiat currency so they will poke their puppets in Washington to do anything they can to control the narrative. There has been a decent dip on this news which isn't over yet however it'll be good for the market eventually as the Korean exchanges were overpricing the coins.
It's going to be a long drawn out battle but I'm confident crypto will win.
Cheers mate.
