Analyse the root of the project and the team. When a project is being developed and launched by an established firm or one with a good number of userbase gives the confirmation of growth. This has happened with several projects, and these aren't mere hypes. When such projects get launched it is very hard to participate on the sale, very few get lucky to make profit out of it.
The developer is a big help for us to decide whether to buy or not and personally, I do analyze their background and know their plans about the new project because they might already worked with project before, and just created another project just to have more investors.
