Having capital is definitely a good thing, but it's not the only factor — and it's definitely not the main one. If you're really actually a good trader, you should be able to make it with the help of leverage.
^Not saying that I advice people to use leverage, of course.
Capital definitely is not the only factor but it's more of a strong leverage to one that has it, for being a good trader then what should follow is nothing but a good capital to reconcile it.
