Its a self-feeding system since it prints its own money which is used to buy "real money" which is then destroyed. This might be questionable and thankfully we have non-PoW/PoS systems that dont do this but the whole Ponzi thing is just nonsense. Its entirely irrelevant if it matches some (your/anyones) definition of a Ponzi or not. Just to usual click-bait "bitcoin very bad" title that gets the HN people all existed to up-vote it. Yes, bitcoin is garbage tech, but all the hate posts will only push it further. People should focus on systems that do the same as bitcoin but without the "bad". There is a multi billion dollar demand that does not go away. A little bit education about FBA systems would reduce the resource wasting from PoW by a lot and all without taking away the peoples freedom to gamble with "digital money".
