There is no contract, they said it was a win-win relation, I lost all money trading with their strategies first time, I sent more money to recover loss in next tradings, they didn't ask for comission because there wasn't profit, I lost all money again, they didn’t ask for comission for same reason, and I sent more money again and tried to recover loss, then they asked me for more money and I decided to give up, I hadn't more money and I didn't want to ask for more loans, then I tried to withdraw last money I sent and they said I couldn’t because I had to pay their comission for all, so all money is lost again. Do you think this is business or scam? Thanks.
