I think that the best coins for this year (besides Ethereum) are NEO, VeChain, Ontology, and IOTA. You can also check these altcoins and maybe buy them: Eidoo, Ethlend.
i agree with these coins. also i support ripple, stellar lumens, bancor, zil, bluzelle. if you manage to watch them all, you can make a big bag from them.
and there are some icos but they are not on the market yet, like sparkster, origo, datablockchain, desico, ...
