I think is very risky to trade on small exchanges especially with large capital. I will advice that trading on small CEX exchanges should be with small capital because the can easily go insolvent.
I have an experience with a small CEX exchange few months ago where almost every users had complained of withdrawal issues but the keep promising users that everything was fine. As a long time user with some of these CEX exchanges, i wrote them several times about my withdrawal issues and even indicated that the exchange could go insolvent because users are stranded on withdrawals predicaments, unfortunately they deleted my KCY information and stopped replying my mails.
As at today, the small exchanges has crashed, worst still, I have not withdrawal my coins, though very small, but I was mindful to that fact that they will definitely crash. The most funny part after crash was that i have to complete KYC again to withdraw my tokens even when it is obvious that everything is not working
