Cryptocurrency has just been speed-running every security and financial scam from the 150 years that preceded it.
When you look at how absolutely crazy it gets, the specific technology play narrative doesn't even matter. You could have recreated the same scenario, if you gathered every slimy douchebag on Earth in a Zoom call and got then to all agree to start hyping portable quantum computing or AI dog translation boxes or, I don't know, algorithmically stable digital dollar assets. You would get the same outcome! Nothing valuable gets made; people get robbed.
