Crypto hasn’t improved our digital world. It’s made it measurably worse through (among other things) making it trivial to profit from ransomware and DDOS-for-hire services. And of course there’s the indefensible environmental impacts and the destabilizing effect on the market for consumer computing hardware like GPUs.

I don’t doubt there exist people whose lives have been improved (for the time being) by the existence of cryptocurrency, but the overwhelming impact has been a disaster.
