HN likes to trash Bitcoin, but at least you can understand where the pro-Bitcoin folks are coming from. If a cashless society is inevitable, would you prefer that all such transactions be mediated by a small number of large corporations? Or would you prefer the option of at least some of your transactions happening through a peer-to-peer system that no corporation or government controls?
Bitcoin doesn't have an undo button. I know somebody who works cybercrime and they routinely get people their money back after being scammed. If they were scammed into using bitcoin that money is gone.
Some of us would much rather take a tiny chance at being "scammed" than the certainty of being at the mercy of the government, the banks and the payment processors. In an ideal world, both of these choices would be available to adults to manage their risks and their own finances as they saw fit, rather than being forced into the latter system "for their own good".
