In 1999 Friedman predicted Bitcoin stating that internet would reduce government power and introduced the idea of digital cash, in order to reduce the power of a third party in transactions. I think that´s a legitimate objective.
Also, a business structure where control is spread out rather than hierarchical such as DAOs, and where a community of like-minded people is working together towards a common interest, without a central authority, is also an interesting figure with tons of potential to create value.
The fact that -so far- most crypto has been about inflated values and speculation does not change this.
The key question is: Why, after all this years don´t we have real, added value applications such the ones that internet brought (email, browser, etc.) to help people with crypto technology?.
In my opinion the answer resides in regulation, the fragmentation of the technology, and the priorities of the people in charge in the crypto industry.
