The scheme is the following;
You deposit money, they give you a bonus, u have no way to say no.
You get the bonus, u go buy tokens: eadx with the bonus, and other coins with your real money, cuz UI doesn’t allow you to buy other coins with bonus money.
You try to withdraw the tokens you bought with your own money, they tell you that you can’t, cuz u bought them with bonus money. Which is clearly not the case.
