The excuse they were giving was that it's possible that money being stolen from exchanges are being funneled to North Korea. It's perfectly understandable that they'd worry about that though. What's happening now is that they are tightening controls though there is still no outright ban. I suppose that would be harder to do in South Korea compared to China since it's just not one single authority who'll make decisions.
Source for the NK claim?
I doubt that, how would money stolen from exchnges end up in NK since it's impossible to transfer them.
And again, if they would be stealing coins, how are they going to claim fiat, with no active banks?
And again..lol...what stolen coins?
Youbit??? Don't make me laugh, those guys get hacked every 3, 4 months or so.
It's becoming their specialty.
Either way,back to the op, there is no crackdown on crypto.
They are targeting exchnges , and I'm pretty sure they've caught onto something really bad.
