I certainly do, and I consider it extremely important as well. I find it simpler with this site https://fx-list.com/crypto-forex-brokers, where all brokers are AVAILABLE to make comparison. Although, it got all types of brokers available with their reviews, but with Crypto brokers, it makes comparison so much easier!
I never use crypto forex broker, and I only use exchanges to trade. I don't join in the name of forex because it will be too risky for me, and I don't know much about forex. For me, it is better to trade in the exchanges because I can buy the coin directly without paying the broker and if I can get profit, that profit will all be mine.
The broker should take a bigger fee and if we calculate, our profit will be less than the real profit because they eat bigger profit from us.
