Crypto is a revolutionary product because it enables users to possess their own units of account. With great freedom, comes great security concerns. Keep in mind, the vast majority of scams are still conducted with fiat currency. Blaming ignorant crypto users does not overshadow the value digital assets provide to humanity. These benefits include: protection from fiat debasement, the ability to transact without intermediaries, global accessibility, privacy, and transparency. We're using the fediverse for fucks sake, so some of these features ought to be seen positively by many of us. You're absolutely right that greedy and gullible are drawn to crypto because "line goes up." There will always be a learning curve for new technology and hard lessons will be taught to early adopters.
