KYC with Sofi Trade (sofi-trade.life) 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: Automated trading options|Easy withdrawals|Multi-currency support|Educational resources
Cons: Some tools only available on higher tiers
