Well I do assume this may be as expected since BTC has tanked and all of crypto has gone down so much, being as the korean people were partially the main driving force pushing the price up, now that it has gone down, they are ones that are left holding their coins at a loss.
I remember MANY koreans were the ones pumping coins like XRP, STORM, EOS, and more. All for what seemed like no reason. Pumps like that always result in people losing money.
I have also heard it is extremely hard for koreans to buy crypto now due to regulations. Something like you must be over 21 or something, and have to physically go to a bank that accepts to give you a license to trade crypto or something like that?
Im sure it will pick back up eventually, but as for now everyone is suffering.
