The Non-Innovation of Cryptocurrency
There is zero evidence that crypto is creating any technical innovation connected to the larger economy, and a strong preponderance of evidence it is a net drain on society by circumventing the rule of law, facilitating tax evasion, environmental devastation, enabling widespread extortion through ransomware and incentivizing an increasingly frothy ecosystem of scams to defraud the public. Nothing of value would be lost by a blanket cryptocurrency ban.
