Greedy people honestly want to get 100% profit or more than that compared to those who have knowledge in trading for them 10% to 25% of profit is enough that is only what I usually see in the community they have their own trading rules set.
Those who have trading knowledge and are professionals certainly already have a well-designed trading plan.
They know when they need to stop and take profits without a follow-up plan, but it's done repeatedly.
I think it's ok to be greedy but you just make sure that you set some rules you need to learn to set rules like 2% to 6% trading rules you shouldn't lose more than the rules you set and anytime you can manually sell once you already gain a target or more than target profit. However, if it fails you shouldn't lose more than 2% to 6%.
So that even if you are greedy and fail to make a good profit you still prevent yourself from losing too much but you lose the opportunity to make a profit.
Being greedy for those who already understand how trading works will certainly provide advantages.
They will reach a price with profits exceeding 100%, it can even be 200% or more, but as the rules you said,
they cannot lose 2% to 6% of profits, or in other words can set Stop Loss and Take Profit features on trades.
But if they keep losing more than expected, they keep delaying selling and in the end there will be a lot of losses,
here trading psychology will continue to play and this becomes a continuing loss.
