Cryptocurrencies are an innovation. With all the problems and areas that need improvement, there is undoubtedly some key technology progress here that we're never going back from. Personally, I think what we're seeing is akin to the first internal combustion engine. It was dirty, low power, fuel hungry, extremely noisy, inefficient, and vibrated so hard no one ever thought you'd be able to attach anything to it. ...and it also made zero people money. ...but eventually it revolutionized transportation.
