Coinsbit is EU only and Crex is EU only. So we havent been able to justify their fee yet - although we told them we are open to negotiate a lower fee for not have ability to trade in the US.
Coinsbit seems huge ($400 million, #38), I just created an account from a US VPN and depositing and trading works, but for withdrawal, somebody needs to test uploading a US document for verification, to double check if it's allowed or not.
I tried the KYC process with Coinsbit about 3 weeks ago and it took 1 week to hear back
I got an email back that my Coinsbit account was not approved
Title: Customer Doc Disapproved
No documents accepted. Please try again.
Reason: "Dear customer, good day! Your verification application was disapproved. We do not accept USA documents. Thank you for understanding."
I asked in their Telegram, "Does Coinsbit not allow users from the USA?"
Eugene from Coinsbit Support Team said "No, it's not allowed"
