KYC with Stock Standard Exchange 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: Fast execution|Good mobile app|Market news feed|Intuitive for beginners
Cons: Would like more payment methods|Wish they had more educational resources
