It would be difficult to qualify Bitcoin as pump and dump without inadvertently also including many other assets at this point (which is perhaps a reasonable position to take!). That is to say, the more time passes, the fewer properties it exclusively shares with things we traditionally consider pump-and-dump. Bitcoin has for example now outlasted many startups (12 years and counting). Again, many people do think startups and/or the VC-ecosystem are a convoluted pump-and-dump, fair enough. Some would say that Uber is a massive pump and dump scheme that gives out rides below market value as a side-effect. I suppose you could argue that Bitcoin is similarly a pump-and-dump scheme that allows some people to for example donate to the internet archive as a side-effect. But if Bitcoin is still around 12 years from now, would we feel safe saying it's probably something "else"?
