It is a very good idea but you need to read a lot prior to investing in anything, as there are many profitable projects out there but, at the same time, there are many holes in which you might fall and lose all your money. Thus, I'd recommend you my portfolio, as I am currently satisfied. Check it out:
1. Cointed
2. Giftz
3. ATF
4. Restart Energy
5. Knowledge

Check them out. All of these ICO's are promising and provide high ROI. Additionally, their whitepapers and companies vouch for their credibility. Let me know if you have any questions.
