South Korea's digital asset exchanges have begun to stop trading some cryptocurrencies deemed too risky for investors as regulatory pressure intensifies.

As reported by local media on Wednesday, 11 of the 20 exchanges that have received a Security Management System certificate have stopped trading or issued warnings for certain coins.

Huobi Korea reportedly halted trading in Huobi token, while Coinbit stopped trading in eight cryptocurrencies and added 28 cryptocurrencies to its warning list.
