Actually no. SOURCEWould you prefer the term Ponzi scheme?
"A Ponzi scheme is a fraudulent investing scam promising high rates of return with little risk to investors. A Ponzi scheme is a fraudulent investing scam which generates returns for earlier investors with money taken from later investors. This is similar to a pyramid scheme in that both are based on using new investors' funds to pay the earlier backers."
Bitcoin is highly volatile. While I believe investors will see a high rate of return in general, there is a ton of risk and the long-term value is in the development of the technology and its global applications. People who talk about investing in crypto technology as a means by which to get rich quickly, or who believe there is no-to-low risk, are wrong.
By this logic, professional sports teams are pyramid schemes. They only generate value because people are interested in the sport and the entities that run the corporations can sell tickets, ads, and licenses. The more people buy into the sport's ecosystem, the more valuable the sport or team in question is. If the fans disappeared, so would the sport.It's not a pyramid scheme because they're seeking investors. It's a pyramid scheme because more people buying into it is the only way existing people actually make money back from their investment.
(You could say that's also true of the stock market, but the stock market is at least somewhat based on real values, rather than thin air.)
I don't understand the argument that there is zero value or that blockchain functionality is being conjured from thin air. People are doing things with it, and there are hundreds (if not thousands) of examples as such online. Even something as simple as a video game being built on blockchain is something (EXAMPLE). It doesn't have to be your particular something, but it exists and is meaningful to a group of people.
