I've done up this spreadsheet of all the cryptocurrency exchanges, which I've actively maintained over the year. You can use it to better select and understand which exchanges are right for you. It even includes data on the upcoming BCH ABC/SV hardfork statements.
You can leave comments on the spreadsheet to mark updates, and I will merge them actively.
You can also find a general resource page of cryptocurrency resources during my evaluation at:
Which is open source and editable at:
Let me know your suggestions and anything I can do to improve it and help facilitate collaboration.
If you do decide to signup for anything, then if you can use the referral link for the service, that would be appreciated, and often you will get a benefit too (depends on the service).
