I don't think if this is a Korean exchange look at the registrant contact below.

I'm sure it's covered by whoisguard.
By saying you have coins there, I assume it came from bounty campaigns but the coins only available to that exchange then that's okay since you don't have any choice, you can try to trade them since your coins are already deposited there and if possible don't try to hold your funds there for long time.
But if you're saying that you really use the site for your regular trading habit, I'm asking why? While there are some reputed site out there.
I'm not saying that the site is cannot be trusted, it's just that I just heard that site and I'm very skeptical having my coins storing there since most korean exchanges are quite vulnerable of hacking.
