Definitely you're on point, there's a way greed have possession on someone and if not managed properly it'll result to some disheartening stories and regrets, it's just like buying and selling, amidst getting some profits from your sales some persons out of greed they'll always want some huge profits from it and they go about increasing the price of some of the products they sell all because of greed, which logically it shouldn't be so, and that's how trading is why buy a coin with $5 and then you are expecting a huge profits from it ranging from 100 it doesn't work that way, with your little sum you can walk away with anything that tops it abit above it's actual price.
In order to manage this greed, I think everyone who decides to trade must first have the right understanding and also good self-control when trading because with these two things, of course, everyone who trades will know better when to buy and sell again to take advantage of the assets they trade because without understanding well about the assets they trade, of course, they will set a large profit limit, but it is very unlikely that they will be able to get it and what you said is very right with the little capital used, of course we must also be satisfied with the profits we have gotten because if we have a large profit target, of course we must have large capital too.
