Iexec(Rlc) is a distributed virtual cloud with an already released product and an incredible team. Bitshares and Steem are incredible investments because they have working products with vibrant and expanding communities coupled with cheap market capitalizations. I also like storj, trac, and lampix. Check all of them out and form your own opinion! I own most of these, so I am biased. Do your own diligence. Good luck!
