Low fee may not seem like a prioritized one as we do see almost all the exchanges are following same type of fee structure and in same level of percentage. For a skilled trader, fees is not a concern always. But, if exchanges start charging fees out of trend means that would be a problem. For example, if they do more than 3% or 5% then traders who target 2% yield per trading may start facing problems.This is the reason we need to confirm where the fees are sitting and only the traders who already encountered such problem might want to confirm these things before start using a new exchange. Overall, I mean to say, confirming low fee still a prioritized one.

What I expect from a new derivative exchange, it should have more volume.
