This whole conversation reminds me of when AOL provided a link to the World Wide Web for their subscribers.
It was the first time that "browsers" - aka, people who browse, but do not produce content themselves - were allowed onto the web in large numbers. It instantly flipped the entire web from a place where creative people built shit and shared it with each other, to an enormous horde of people consuming/copying/commenting on your stuff.
Which was useless. These people were using the Web like TV, rather than the hot rod auto shop that it was. What the fuck do I care what some non-creator from Poughkeepsie thinks of my work? What have THEY done?
Bitcoin, et al, seem to be in a similar place: A great tech idea was just about to hit its stride and become something much bigger and more powerful... and then the looky-lous came in, and have artificially skewed the idea/product/technology.
From someone who has lived through this change four times: It ain't coming back. It is now the property of the speculators. They are there, they are in, and you cannot eject them. They are now a fact of the market, and just need to be endured and understood.
(Incidentally, this is why I don't play PubG, a game I know I would love. It is over-populated with people who are REALLY GOOD, and snipe any newcomers constantly, until it is no fun. This creates an isolated cadre of the "elite" who play it until the company can no longer sustain the server costs, and goes out of business or sells off to someone else, because they can't get new users to play.)
