I had a dispute with Coin Wealth Trade and went to their complaints process. They have an internal team that just defends the company. Then they said I could go to an ombudsman - but the ombudsman they use is industry-funded and rarely rules for the client. The system is rigged.
Pros: Good analytical tools|Detailed reporting|Market news feed|Dedicated account manager
