South Korea blocks 27 crypto exchanges, including BitMart and KuCoin

South Korean regulators have blocked 27 crypto exchanges, including BitMart and KuCoin, escalating earlier restrictions that targeted mobile apps to full website blocks. The action targets unregistered exchanges operating in the country before investors report losses.

No details were disclosed on the full list of affected platforms, the legal basis for the blocks, or any recovery process for existing users. The crackdown continues South Korea's tightening oversight of foreign crypto platforms operating without local registration.
