I think it's also impt not to be swayed too easily by the "crowd".
Sometimes, "liking" a project is subjective. Lots of popular projects, crypto or otherwise was turned out to be infeasible and unprofitable, so even as we believe in the tech, we must also be careful to put our money (or crypto) where the chances of returns are most valid. That would require a serious look into all aspects (tech/team/hype/longevity) of a project.
