Now Korea seems following pathways of chinese government sooner or later all government will try to have deep control over bitcoin exchanges and they will put all their efforts to track each and every bitcoin transactions but all of their effort will go to vein.
This will increase interest over decentralized trading platform and P2P marketplaces like localbitcoins. In short term this can have negative effect on price.
i think the exact opposite; korea has historically, been receptive to technologies and innovation. my thought is, they're having exchanges examined in order to ensure safety and security for the users, and make sure the exchanges are doing exactly what is advertised without any illegal / shady business going on behind the scenes. that being said, i think overall, this is a big step in the right direction, and will probably increase both bitcoin's price and korea's influence in the cryptocurrency scene. hopefully, we might see a cryptocurrency community based in korea that is relatively scam - free and an envoronment in which bitcoin can expand with newcomers feeling comfortable and reassured that they won't be scammed or stolen from.
