Thanks for posting this, you are right you can trade here even if your account is not verified, but now that they started asking KYC even to those trading low amount, it's time to look for a better exchange, I would do KYC only if I'm trading thousands of dollars I only do hundreds or even lower.
Sure, it makes sense only for big traders.
Not for big traders but aswell with the small ones since we are dealing with money and we must be careful upon executing some decisions upon dealing with small time exchange.
