Cryptocurrencies are nothing like cash for one important reason: they are not subject to physical constraints.
You cannot easily scam millions of people around the world out of their hard-earned cash in a couple of days. You cannot easily move millions of dollars in cash without conspicuously hauling objects around and/or engaging many people to help with that. You can reverse a cash transaction immediately by grabbing the person and calling the police. You cannot maintain anonymity when dealing in cash without giving strong cues to bystanders and counterparties and risking being recorded on video. It is not the purpose of cash to avoid any of those “downsides”; but it clearly is a feature of cryptocurrencies.
Cryptocurrencies are a qualitatively new thing humanity has never had to deal with ever, no matter how insistent are cryptocurrency aficionados’ in calling it merely “a digital version of cash”. This serves their wallets, by suspending deserved wariness and encouraging unsophisticated people to invest into a financial pyramid, but not truthful description of reality.
