Great point. It is rather outstanding at the number of people mixing in with things they yet fully understand.
For me Ethereum and Steem makes sense and have the most longevity, but unlike some other block chains these are actually backed by something while being fast and secure.
Ether is a bit harder to build upon then Steem, but watching the incredible creation of the application called Acrade City and their impact really opened my understand of the technology. When the Commercial world understand the power of Smart Contracts Ether will blow up rivaling bitcoin if not more.
As for Steem. It just makes sense to me. I fully believe in being backed by the content creators. DTube, DSound, Busy, Utopian, and more. Once the mainstream world catches on to what this is Steem will go past the Moon.
