It really is difficult. All you need to do is your own research. Read a lot and try to learn more and more everyday. Don't invest more than you can lose. I can suggest you the Crowdholding platform. It is a co-creation platform that connects the crowd with the entrepreneurs. Although their ICO is ongoing you can still get their tokens by participating in the platform and it is very easy: You sign-up, choose a project, leave some solid comments and get rewarded for them!
