Brexit Millionaire located at brexitmllionaire.site, which claims to be a Forex trading platform, is deceptive. Brexit Millionaire is just another so-called trading platform that convinces members into opening trading accounts with a broker. They will make a commission every time those online users trade, whether they lose or earn money on their so-called investments, taking part in very risky trading. Also, Brexit Millionaire claims they were featured on Forbes, but I could not find any article on the same website regarding them.
