Well, I personally advise to do your good research before investing in any project.
- study WP thoroughly ( I can say that many projects' WP is just pretty words with no sense or real application)
- look at the listings and the rating (such as ICO bench - that's one of the best)
- check the team and when they started to work on the project (as for me, I don't trust teams that have no linkedin pages or relevant background)
