Overall, it is still early in the development of blockchain platforms and, for the most part, they have not achieved widespread adoption by consumers in any meaningful sense. That being said, I think Bitcoin has clearly won the "store of value" use case and I think the implementation of lightning gives it some more transactional/development promise. I think ETH has most of the developer mindshare which is always a good indication of future promise. EOS just launched and clearly has the money to attract developers ($4.1B) but we shall see where it goes. On the lesser known front, I love the team at 0x (ZRX) and am bullish on privacy coins like Monero (XMR) and Zcash (ZEC). I also think Augur (REP) has a ton of potential and a strong team.
