Using these Centralized Exchanges on trading and other crypto related activities, I observed they give these Trading Vouchers especially if you just sign up with their CEX platform.
I still don't even know how these vouchers work because they are mostly related to Futures/Derivatives Trading which I am still a leaner and can't risk loosing my funds trading what I am not yet a step better than a regular trader, my vouchers end up getting expired each and every single one.
I just want to know from you people, if you make use of these vouchers and possibly how it works.
