A ponsi scheme is fundamentally different than a market. With a market one day you trade five USD for one BTC. The next the best offer your able to get from anyone might be two USD for one BTC. That's just the nature of any market for anything. Value for anything depends on who comes to the market and their bias. A ponsi scheme is nefarious and more of a shell game. When the asset is gone, it's really gone and not coming back. There eventually aren't units to redeem because the originator took the aasset. If BTC or crypto were a ponsi the analogy would be satoshi hacking your wallet and draining your funds. In traditional crypto there aren't returns, there's just potential for it's perceived value relative to a base like the USD to change.
