Good points. I would say you have the same factors as I recommend to others:
1. Team - is the team capable of doing the product, do they have experience and skill set
2. Market - is there a niche or share of existing market will be made, is the market large.
3. Token model - is there a purpose of the coin, do you think it is useful.
4. ICO structure - how will the funds be used, roadmap available, do they need that much money.
Agree with this opinion, I want add more about tips pick the right ICO,
5. Business Sector - analyst the main business sector, is that kind business has big capital or not.
6. Roadmap - see the roadmap, how the next roadmap will be, is the project will expand more in their apps or anything.
