It is very important to create demand in the coin. That is why it is necessary how coin is developing, check the ecosystem of the project and the team of the project.
What you're saying is a very common thing for everyone to do on any new project, because without checking each one there's no way of knowing how far a coin has grown, so I don't think it's worth talking about.
Even if you study projects, this will not give you 100% confidence in the growth of this or that project.
Ultimately, everything always depends on where the market is globally. If Bitcoin is growing, then any project has a chance, if not, then only the strongest.
