Ok, My opinion is too loking for small hot prospect projects or projects which all suspect has great advantages but their price is not exploded yet like NaVCoin - which has all needed to be more than a normal project. Hidden in the shadows there is a project called XSPEC - an offset of good already dead ShadowCash with Hierarchical Deterministic (HD) multi feature wallet. Here is the link to their btctalk thread: https://coinmarketcap.com/currencies/spectrecoin/. Also hybrid like Pivx is a good opportunity. You can try PosW too - they releases a hardware wallet. Many coins with much longer live can dream about hardware.
