Well its true that investing with high capital will have high gains but also remember that its not only about how much you invest or you put into it but how you did it or what is the strategy that you use to have higher chances of profit rather than losses. I know some small time investors who were able to gain much because theyre able to master and fully understood how it really works. Though losses can still be present, its inevitable but at least you get to lessen the chance of incurring high losses. I think it still a matter of skills regardless of how much you invest on it.
