I think Wirex or Revolut are more matured and used than crypto.com. I don't have the numbers, to back it up though, but any of those guys would be helpful if you need expertise for fiat on ramp, credit card etc.
Just a quick update about the Dev Campaign. For those who are clearly bounty hunting, you will not receive a reward. This "bounty" is meant to help users learn about fusion, while getting the chance to contribute to the projects sucess. Submissions of unrelated resumes and/or work that is taken from the internet will not be accepted. Brand New githubs will be rejected without proper proof of work handed on the side. New linked in accounts where the only activity is the liking of 3 crypto related articles will also not qualify. Please do not spam admins PM asking for a reward, especially if you fall into the aformentioned categories.
