I think my most promising for upcoming price action will be NULS. Lots of competitors in this space but NULS already has a working mainnet, and is priced far below projects with similar specs... I just think 10-25X is possible.
Other projects I really like for the future are 0x, TheKey, Unibrighht, and Waltonchain... I think certain uses for blockchain will prosper quicker than others.. identity and supply chain seem the most adaptable right now and Waltonchain/TheKey are my favorite projects in these areas... along with Unibright helping templatize blockchain implementations into businesses.
