In my opinion it's worth taking a closer look at:

  • Antshares/NEO which is a chinese Ethereum competitor
  • SiaCoin - which is a distributed cloud Solution
  • Ripple - promoted by banks and used for international bank transfers

and probably also IOTA. But i need to dig deeper into detail in that one..

Thanks a lot for the answer, I'm gonna check them out, all of them :)
