I hear this alot and do not understand it. How is it a ponzi scheme? there is no fraud taking place, people are aware they are buying a token for 300k and taking on that risk themselves. If they lose money there is no one to charge as no fraud has taken place.
While you are not wrong about organizations trying to obtain a larger budget, but it it a fallacy to assume a priori this is the case. Regardless, the budget required to research UAPs would be a drop in the bucket for what is spent on defence. There are much more efficient ways to attract tax payer money.
Contrarily if they truly are observing things they cannot explain should there not be money allocated towards researching this? If not only for air safety of the pilots and crew.
