This news will clearly push the price down more as people will digest the impact and content of that article. Specifically, people who are new to crypto will most likely sell (already sold) their BTC after reading this article. The veteran ones will just likely shrug this off as they experienced this same kind of "FUD" in the past in a more greater scale. I think, South Korea will not ban it but they will put a very strict rule/regulation regarding tax payment for crypto trades. Well, I'm just hodling my BTC stack and will not budge because of this issue.
This is just an opportunity to make more money with bitcoin, the price will go down but after this the people that are now unable to trade at South Korea will move their money to other countries and exchanges, and then we will see a pump, this is nothing new, people making a fortune in crypto are not going to be stopped by something as small as this and true holders do not care at all about these news as well.
