Hey everyone. I'm working on a small research paper about crypto trading. I need your help to collect some insights of what both engaged and not so active cryptocurrency traders look for when selecting on which derivatives crypto exchange to trade.

What do you expect from the ideal crypto derivatives exchange?
Name 3-5 most important things ranged by importance.

E.g.:
1. low fees
2. high leverage
3. wide range of assets
4. long exchange history & reputation

I will post the research here when ready with it. The more answers I get the better representation of each group. Thanks!
