I think we almost all agree that cryptocurrency is a revolutionary thing. It's difficult to see how revolutionary, because we are only beginning to understand what can be made possible by it.

I often see it compared to the advent of the early Internet in the 1980s, when nobody really knew how big it would get, just that it was "revolutionary" and would become huge.

This may be an overestimation caused in part by bitcoin stakeholders trying to promote the idea. But a very similar thing happened in the 90s when everyone was buying tech stocks.
