I split my investments in crypto to

UBIQ - 15% (also still mining)
DECENT - 15%
SONM - 70%

I think SONM is the hidden gem. They just released first version of their product and a wallet.. you can test whole product by yourself, full release will be in summer. If you look at the technology, white paper, team or even their website, videos, graphical design you will realize how undervalued this coin is. Price right now is a joke sitting at 0.30$ with potential to jump 4-5 times any day (to go even with golem coin), expecting to go to 5-10$ in 2018 and even higher later.
