Ren Trade Network Broker Review

I deposited money and the first two objectives were met, then I invested more and then I couldn't withdraw anything anymore and it just tells me that I have to meet one more objective and deposit more money. First, I deposited 100 and it returned 130, then I invested 200 and it returned 260, and then I invested 1000 and from there it didn't return anything and it told me that I have to invest more for the next game, so I deposited 3000 bs and then it tells me again to meet the other objective... but I didn't have any more money.
