I have seen many advertisers like this buddy. All turn out to be fake. I havent heard of Merits Capital. But have heard of Ashwani Gujral. If the famous person and book writer can bring the account down to 70% then how can you gaurantee that.
If you and your company are so much sure that you can double the money, then y not give it written in legal papers. If you say that you double the money, okay, thats a fair play. But if you lose your customers money, then who is responsible. The person who has earned that money by his hard work, will be left to worry.
I am willing to give you my whole account, but give it written on legal documents that you can double it, other wise money back with penalty.
If you cant then, you are just another snake oil vendor, with bogus material.
Sorry for the harsh words, but thats the truth in share market. I can give you many examples where there are performance sheets, big companies, but still the actual service takers bit the hard tongue at the end.
