I wouldn't look so far as the "catch" is obvious, neither of you will make something out of a dead coin but they will have you as a Lead and that is what those platforms are all about...sarcasm aside, you might get something out of this trade if the bonus they will give is respectful and you can prove your trading skills in the traditional markets
