Coin 4: Dogecoin
(Yes im serious)

Why:
- Running for almost 3 years
- Strong community

Coin 5: Counterparty

Except for counterparty, agree that these alts are going to be around and strong in 2017. Doge is always dear to me, I just like its playful theme.
But as investments? I couldn't say I'd feel strongly about any except bitcoin itself.
