https://en.wikipedia.org/wiki/Ponzi_scheme

1) require an initial investment and promise above-average returns

2) money cannot be withdrawn for a certain period of time in exchange for higher returns.

High investment returns with little or no risk.? Overly consistent returns?

Your argument is that if I buy an ETF for gold and they charge 2% to keep the gold safe and manage it. This etf is a ponzi scheme as they need have holders to keep the thing going.

As the transaction fees go to miners you could then argue VISA and mastercard are ponzi schemes?
