Exactly. All of these alt coins implement a unique technology, whenever it is smart contracts/dapps, or decentralized exchanges, or even cloud storage from within the blockchain. I think that all of these work well together in a unified blockchain system. Imagine that instead of having a coin for each technology, you get a complete system with all the features of the above mentioned coins.

As for me, my most favorite are Ethereum, Maidsafe and BitShares. They are one of the most advanced alt coins out there, with very huge potential. Take a look at ETH for instance, in which is one of the most popular cryptos out there next to Bitcoin.  Smiley
