I know you are looking for suggestion on what new coins to invest as to give you idea on what to research/look into.
I cannot give you a suggestion as my opinion would be bias. So I will just give you some tip on what I usually look into.

1.) Check on ICO's that has product already - If the product is already there and is already working, your investment are more likely safe and you'll soon get your rewards.
2.) Check the community - If the community are solid and you can see plenty of support. They usually create noise and will attract investors and that will most likely create a value to the coin.
3.) Check the team behind - If you see an active team and can always see updates and progress, it's a good sign to me. It could be worth to invest.
4.) Check the Popularity - This will contribute much to the value but you have to be careful because not all coins can maintain its popularity, they also crash big time. So you have to know when to join and when to get out if you base your investment only to popularity.

This is not a professional advise. These are only my personal tips I can give with my short experience here in cryptoworld.
