1-Reputation
2-Volume
OP, I don't trade derivatives and never have, but mikeywith is probably right with his top two criteria--reputation is
extremely important in the world of cryptocurrency, because there have been so many exchanges that have turned out to either be outright scams or have gotten their customers' funds hacked. I think it would be critical that the site be secure and have whatever protections are in place at other derivatives exchanges--like the CME and anywhere else you can trade stock/commodity futures.
Volume is also important as well. I think one of the reasons why Bakkt hasn't succeeded like many thought it would is because there aren't many people using it as of yet, and the market needs to be liquid in order for traders to have confidence in it.
Anyway, good luck on your report, OP. I don't think this is the best place to get answers, but I'm sure you'll at least get some.
Thank you for the answer! Reputation comes with strong security, this is why I am all in for strong withdrawal protections put in place.
From what I have seen until now the most important factor seems to be reputation therefore strong security etc..
