Stratis: essentially doing something very similar to what Ethereum is doing - smart contracts and Siacoin: Distributed data storage. An alternative to Box, Google Drive. The big corporations would not have any access to your data in this point.
Stratis is really giving some huge push for itself in the crypto world and I must say it is impressive.
I am really looking forward to see how much It thrives in coming years and now that most altcoins are really having a hard time is the best time to have some for the upcoming growth in few years to come.
