You are right. Bitcoin today has such a price and popularity thanks to people who believe in its future. In the crypto-currency community, one should be guided by the rule,, if not I who then,, A large number of ICO startups already now need a blockchain of developers. I think this is the most demanded work for the near future.
There's not a whole lot of substance behind all this 'blockchain' stuff. Bitcoin is great and useful. But there's often no justification for using a blockchain in many of these projects. It's just a buzzword used by people trying to cash in.
