I wrote a topic based on this before which you can read here:
What are ICO's and investments advices

"Things you should look for before investing in ICO's:
- Team: How is the team, do they have enough people and the experience of pulling it off?
- Idea: Do you believe in their idea and is it realistic?
- Roadmap: Do they have a roadmap, and how much time do they need to launch their product?
- Hard cap: Unnecessary high hard cap often means they are in for the money. Lower hard cap is usually more profitable because it's easier to multiple your investment
- Bonus: How much bonuses has been given during the pre-sale and ICO? If someone got tokens at a much better price than you do, then you might get burned.
- Tokens for sale: The higher percentage of tokens available for sale, the better it is for the investors.
- Team's tokens locked period: How long are the team's tokens locked? And are they locked at all? It should at least be locked for 1 year minimum to show the investors that they believe in their own project and won't sell their tokens after a short time.
- Competition: How is the competition? Who are the competitors and what does this project has to offer compared to them?".

I hope this will help you finding great ICO's in the future!
