The VC model has always flirted with being a Ponzi scheme, but ultimately some startups _do_ make money somewhat consistently, so the model is risky but fair to retail investors. But a crypto project is not a traditional scalable company. It does not make money as platforms traditionally do. It's open source and distributed. I truly cannot understand how it differs from a huge Ponzi scheme.
With crypto/VC/normal stocks all having many characteristics in common with Ponzi schemes, at least the game is relatively well understood. For all of them, there are institutional investors capable of market manipulation, as well as the information and know-how so as to typically adjust their positions so that the majority of the people left holding the bag are retail investors.
