Your return in investments are commensurate to your earnings,you can't expect to invest 100$ and earn more than someone who put in a 5000$
It's just basically easy to figure out,the major constraints in investing is limited capital,and so since the rich have enough capital to throw about,definitely they'll earn higher than those with far less capital
Smartness,patience and less greediness are vital tools in trading/investing
But the major determinant is investment capital,without it, the aforementioned tools are useless
I agree completely. Capital changes everything and this is what differentiates the rich from the poor in a huge way. This logic applies to literally every financial market and it will always stay true. It is infinitely easier to earn huge profits by investing more money instead of trying to turn small amounts into big money. 2017 was an year in which even the small traders hit it off and earned big through small investments which is why you can only imagine how much the big traders earned through their large scale investments. This difference will always exist and the rich will always have the advantage.
