It's funny if people will believe this, c'mon no one will put their money on any untrusted third party site and probably won't risk the money for some bucks that after all it wasn't true. You should stop what you're doing buddy.
I think people now is smart enough to distinguish the true from a lie.
You probably have not spent enough time together with people online then my friend,,, trust me, there are plenty of people who would give their money away for the chance of quick profits. Guaranteed profits is especially what people like to hear. They do not listen to logic, they only listen to greed.
If people want interest, then they should just go and deposit money at a bank and see inflation eat their interest rates away.
