My major parameters before I invest into a project is looking at the
1. Team: The team really have a great role to play towards any project development. Sometimes the use case does not always work. Its the seriousness of the team that will make the project and its use case great.
2. Another thing I look out for in any project is the roadmap and white paper. Bear it in mind that these are just paper works. And that even a quack project can come up with a mouth watering roadmap and white paper. Checking at the roadmap and white paper, one just need to technically review these before deciding.
3. Other things I can look out for is Funds. Does the project really have fund to backup? Often times I see a lot of projects without any meaningful funds to back it up and I wonder how they intend to cope with the project development and all that.
