Most will be failures in the same way that most new businesses/startups are ultimately failures. BUT the difference is there is actual experimentation with money now in a way that there never was before.
99.9% of this "experimentation" is simply companies tying ownership of a token to a permission to access a web service. And the remainder of it are clueless tech brained morons finding ways to re-invent financial instruments (like residuals, profit splitting, and derivation) that have been around for hundreds of years. You don't have any new insights into financial systems, you just want to be at the top of the financial system and collect rents
I personally have never been involved in crypto or bought anything crypto related. I have no incentive either way in its success or failure. I've just lived long enough to see what happens when stuff suddenly goes 100% digital, the pace of iteration, exploration and adoption rapidly speeds up while the costs of doing all three decreases.
I think something interesting will come of it, even if I cannot say what that will be.
As for holding out hope something will come out of crypto, using your example of mp3s and digital video, as soon as those were available to the general public they were RAPIDLY and enthusiastically adopted by the entire public. In the last 10+ years the crypto audience has gone from libertarians and fans of illicit drugs to libertarians, gambling addicts, and developers hoping to skill into the "next big thing".
How involved are you in the space to make this claim? Are you staying informed? What is your highly confident language based on?
Can you tease out how you come to "1000x worse"?
You are incredibly confident, it leads me to believe you have some big blind points.
