I think this Blockchain FAD is enough, there are alot of things that doesn't need blockchain technology that some people are selling here in the name of raising money. 90% of this projects will end up as experiment and only 1% will probably see adoption in real world
But that is the way things are, when the internet had its boom in the 90s there were a lot of bogus business and investments but out of those there were many solid proposals that became the giants of today.
