It was inevitable and trivial to predict, which people did, and the cryptbros laughed at them coz that's how old people think.
We put so much law and limitations about anything money purely because at times when we did not, stuff went wrong.
The whole idea of currency without any laws and limitations around it means any and every problem that those law were supposed (some do it better, some worse, some make actual problem worse, not trying to pretend they are perfect here) to help with will happen, easily, with the "new money".
The fact that on top of all the old problems the crypto invented a whole set of new problems is just a little turd cherry on top of a manure cake.
Okay, that was harsh, manure have some actual positive use
