Bitcoin and cryptocurrency has severe flaws that are either well known (insane energy use) or severely overlooked (securing data is hard, securing data that is also cash is insanely hard). But calling it a ponzi scheme is a lazy and unhelpful as calling "fascist" any dictator or authoritarian movement. Anyway, the article argues that it fits the moniker because it has no value besides senseless speculation. It just ignores the one legitimate use it has, and it's one that should be hard to miss because it's right in the name: payments, like coins. That's not to say it's a particularly good tool for that, you can argue all you want about it, but that's what it's for. International reply coupons are of really limited use as well, but they're not a ponzi scheme, the ponzi scheme used them.
