From what I understand the SK banning crypto stuff was taken way out of context. The real situation is they are looking to ban anonymous purchases/trades of crypto, not ban crypto buying/selling in general as most people have assumed (jumped to conclusions).
This shouldn't come as a surprise that government WILL be cracking down on anonymous crypto buying/selling, as they want to make sure they can get their cut (taxes) as they see fit (this is starting by targeting the fiat entry points, and will soon expand to targeting "privacy coins" in general).
I strongly doubt a blanket crypto ban in SK is in the cards, but I do expect some regulations to come out that will change the SK banking industries anonymous practices and force the crypto exchanges to better enforce basic KYC rules in the somewhat near future (a trend that is surely going to also take place in other regions of the world in the next few months/years).
