A few days back I bought a token from Launchpad. After they Launch on Pancakeswap I made 1.5X and sold. I was happy with that. But unfortunately, the token price grow double every day, then I bought again at the higher price. I thought this was a chance to multiply my portfolio again. Even though it grow 5x but O didn't sell that due to greedy behavior. Eventually, the project rug was pulled and skipped with all the funds. That means I lost everything even including my initial investment. This is how greed destroys us and scammer takes the advantage.
We should sell when we are at a profit. But not all who do not sell are greedy, I think they have trust in the developer and are very positive that the market will continuously uptrend. In your case, if you set your selling price and it has not been met, I do not think that it is greed when you end up bag holding worthless crypto because of a rug pull. It is an unexpected event, and probably already a plan of the developer, from that no one can do anything.
