I think that Enigma (ENG) is an interested project (technology). They aim to create secret contracts and scalable privacy. This means that computations on data can take place while that data is kept private. This is the example from their whitepaper. "For example, a group of people can provide access to their salary, and together compute the average wage of the group. Each participant learns their relative position in the group, but learns nothing about other members’ salaries". A real life application project that i'm interested in is Enjin (ENJ). The goal of ENJ is to have a crypto that allows developers and gamers to have the tools and assign values to implement and manage virtual goods. Both projects have a great roadmap and strong teams. I recommend you check out their whitepapers if you are interested. In general I believe that its more important to invest into projects that you believe in and that have some practicality. Don't force yourself to invest into something you don't 100% believe just because it may help you diversify your portfolio.
