Excellent question.
Projects of which there are several, meet all the basic information either at the bare minimum or maximum as a legitimate project, yet still point to the very question in which you have raised.
A simple litmus test would be broken down in two parts.
(a) Are you seeking quick riches, seeking to high APYs from 1,000% to 1,000,000% aka greed?
(b) Does the project require a token/coin, and if so what Real Word Use Case (RWUC), what Real Word Problem Solved (RPS)?
If you fall into the (a) category. Then no amount of information can help. As such projects I believe are playing on FOMO for those who missed the boat for BTC, ETH, and or any previous coin or token that mooned no matter if they had a use case or not.
If you fall into the (b) category. Then you are required to do serious, Do Your Own Research (DYOR), which you should also seek to apply traditional economics and finance principles.
The problem here, is that the technical analytic skills across various disciplines to properly evaluate a project. The masses lack.
Which is why so many projects have come and gone, either as total scams, honeypot token projects, and or rug pulls, the latter meeting a legitimate project, but no intention to see through project or project was designed to appear as a legitimate project with scamming consumers at the final stage, while hiding behind technical jargon or simply disappearing all together.
My best tool to acquire information is watchin the most practical and honest YT influencers in the space. Not YT shillers.
