I see this as a spam thread, so please change my mind by answer these questions :
What do you think when it says this is a spam thread? If you think so, please do not reply to anything, I do not need disrespect from you
1. Are you a Korean? Or a Korean speaker?
2. If you want to 'test' the exchange why would you need to know it from others? (do it yourself!)
3. There are several well-known exchanges already, what is your purpose by looking for a new exchange?
Please note that there is no centralized exchange that actually secure, nor safe.
If I'm Korean or I know Korean, I won't post this topic here. And I cannot test this exchange, do you think I should deposit some money on it and check the safety? It is crazy when you speak. I don't want to lose any money, because it could be a scam or any reason not for foreigners.
On the third issue, you're really silly
Some altcoins are only traded on a limited number of exchanges, which is why large exchanges cannot meet.
