When it comes to Altcoins, I'd suggest that you take a look at ETH, IOTA, and NEO. However, when it comes to ICO's, consider these ones:
1. Bee Token
2. Giftz
3. ATF
4. Cointed
All of them seem very promising and I strongly believe in their long-run stability. Check them out and let me know if you have any questions.
Very nice list, is it on order of importance? Because I would change that to be something like:
1.Cointed
2.Giftz
3.Atf
4.Bee Token
NEvertheless, all ICOs you mentioned are great, I have invested (or will invest in ATF) in all of them and have not regreted (was a bit unsure about cointed in the beggining but changed my mind after doing some research)
