This exchange is less well known so traders don't want to see it, and only limited coins are there.
Because they are new exchanges, I believe that there lot of new traders migrating from Bitmex or other margin exchanges to these exchanges like Deribit and Bybit.
I also know some people hate Bitmex because of their KYC, some of them are surprised why they tagged that they are living in the US while they are not.
