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.
I have to agree with self control because many traders don't have that and it makes them to get easily moved by the way the market is reacting to any news that they act and make decisions in a rush which either causes them to lose the trade or not make as much potential profits that they would had been making. Having self control is underrated as one of the qualities that a trader must have. Self control works together with discipline and many others good qualities that helps you to become a good traders.
Greed is the worst enemy of a trader, not only will it turn you into a loser but also an addict too which is worst because you're going to keep trading despite it not working in your favour. Trading and becoming victorious needs alot of training and learning to perfect the strategy that you'll be using and not depending on luck.
