Ponzi schemes require returns, and more specifically the source these returns being the newly invested funds rather than actual trading/investing activity that becomes the scam. A crypto security on its own doesn't guarantee or promise returns, and gaining value because of other people buying in is no different than company stock also rising in price because of demand. That's just how trading works. The potential issue is if people bought in because of misleading or false details rather than public information.
