Being greedy is the biggest enemy when trading. You lost your focus and you end up making impulsive decisions that will certainly lead to losses in trading. And because of greed, it will ruin your target goal in trading, that's why as much as possible, avoid being greedy at all cost. Although there's always greed deep within, but at least learn to control or lessen it. That way, our motivation to make potential profits with trading will certainly be reachable for us.
You are right mate, I believe the reason why some people prefer copy trading or bot predictions is because they can not make good trading decision without being caught up by their own emotions which can lure them into making a wrong decision that can cause losses. While trading, some trader might have obtained a good amount of profit but because of greed, they would decide to stay longer on the trade and while doing so, they can experience a huge lose. Such lose is cause by greed.
Most of the time, greed really push you to change the direction of your plans, there are position which you already reached your target but instead of stopping you choose to keep trying to earn more, and in time that the direction of the market turns against you, that's the time that you really regret why you choose to stay instead of quitting and withdraw the money that you supposed to earn.
