Remember when blockchain was going to change the world? Yeah me neither.
Like all "new, 'it'" technologies or discoveries, they get old and the hype passes.
I suspect crypto currencies will devalue up to 90%. This is just a guess right now
but in looking at previous historical manias this has been the norm. Railways of the 1920s, tulips of the 1600s, Dotcoms of the 2000s, soon cryptocurrencies and eventually AI hype. ALL OF IT ENDS UP THE SAME WAY, replaced by something shinier that "will change the world" because "this time it's different"
Good luck.
