WAVES (with NG nobrainer) - fastest blockchain in the world + DEX
OmiseGO (obvious)
Biggest upside returns:
NEBLIO (better ETH version with 8 programming langs)
SPECTRECOIN (one of the best upcoming techs in anonymous sector, price is undervalued)
Its been x3 past wek already but its gonna be up to 5 bucks very soon

Neblio will gain a lot of ground pretty soon.
Other than that I highly recommend looking into
Oceanlab. If you believe in Waves, Oceanlab becomes a no-brainer and has so much room to grow in 2018.
