In my opinion it will probably all be a subjective decision as with most companies who prefer quick profits before innovation. As such most investors buy bad tokens to get quick profit. During this time many bad projects will suddenly pump for a short time and then the project will suddenly die. The reason for their short pump is that they will sell tokens and cheat investors out of their money. I don't want the market so should buy dependent tokens with certain timing.
You spoke well. Many people investing in their memecoins because of to make quick profit and not because they want to invest for a long time investment and as down me the investment that can give me gain in the long run is the best project to invest with. When you invest in a crypto project in long term and it gives you profit at the long run then you will know that that project is a legit one and not for scamming people but if you are looking for a project that will give you quick money then be prepared to face the tone of scamming.
Many have fall into the trap and many are still falling. Though when a project is launched in most cases the scam counterparts are the once making comments to praise the project to lure people.
They can pull out their profits at a short period of time but if they think the coin is still doing well, they will still re-invest on it again and again, and maybe they will get to the point of holding the coin for a quiet a long time, only to gain more profits and cut their hassle and expenses for the transaction fees.
We can't predict the future and there are cryptos who do really well for ages but suddenly crash. Their devs decided to pull-off a scam for some reasons. It's hard to believe on it at first but I think if we have benefited greatly at them, we can only move on quickly. They are still better than those early scam projects. It can be hard to detect them but we can start investing small amounts at first.
