What a way to go down
South Korea bans ICOs but also banned margin trading. Consider that seemingly most activity in Bitcoin is coming from Korea this could have a huge impact on the price. Should we expect the price to collapse without the margin traders of South Korea or the Chinese? Little by little, money is being removed from or drained out of the crypto-space by regulators. This can happen via complex regulations which require hiring a bunch of lawyers or it can be restrictions on ICOs or it can be banning of margin trading.
It is true that margin trading is high risk but day trading generally is supposed to be high risk activity. Is there a good reason for a ban on margin trading in it's entirety? On the other hand North Korean hackers are accused of being involved with cryptocurrency so that could be enough to trigger the crackdown both in China and in South Korea.
