One of the reasons why traders loose money everyday in their trading is 'greed'. A trader will hear about a particular coins he wouldn't even do research or proper findings to know the future of the coins which he wants to trade his money on but rather the greed in the trader will push him to use all he has with the aim of making 4 or 5 times of his trading capital.
That is why we should not chase for the highest profit if you don't know how to manage the risk because that means if it doesn't expect your goal then it's going to be disappointed for you and it may affect your emotion thus makes your trading experience even worse then just making a normal and decent profit. 4 or 5 times of the trading capital is pretty difficult without any big news just saying.
