Bonafi shows good results. Estimates on many resources are quite high.
What are your competitors and what is the likelihood of your rivalry with them?
Estimates mean nothing at all. Almost all projects with a rating of 4-5 bring stable losses to investors. It is necessary to carefully study the project.
The main problem of investors is their hope to make a profit immediately after the ICO! Token goes to the exchange and everyone is waiting for a tenfold increase in the price. It's impossible. After 1-2 years you can objectively evaluate your investment, not earlier.
The conclusion is only one: carefully examine all the documents of the project, make a deep analysis! Your profit will depend on whether you choose the right project for investment. Or consult with experienced investors.
