KYC with AI Holdings (aiholdings.io) is a nightmare. I submitted my ID and proof of address. They rejected it and asked for a utility bill. I sent it. They asked for a bank statement. Then they asked for a selfie with the ID. Then they said the selfie did not match. I gave up.
Pros: Segregated accounts|Low minimum deposit
Cons: Mobile app could be improved|Minimum deposit could be lower
