The minimum capital that is required to trade effectively and compound profit is 50$; anything below that means that you are literally wasting your own calls, signals; because without a good capital; the only way to make money is if you are making over 100% profit which is not sustainable. Your profit is someone else trade capital; so i implore us to twice your trading capital.
And once again, if you are to scared to loose money; then don't trade, it is not for you
it's true that capital has a big influence on trading but it doesn't always have an effect. as long as you don't have the skills and good analysis when trading then all the big capital you have is in vain. Trading is not just a game of capital as you say, it is a game of psychology, skill and analysis too.
