KYC with TradeChain Mining (tradechainmining.com) 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|Instant funding|Risk management tools|Reliable uptime
