We don’t accept deposits, we don’t do loans. We only change your large bills. How do we make money? Our secret is: VOLUME.
LOL. That was a classic.
I had the same question. If that bank makes no loans, they must either pay no interest, Or they do one or more of the following:
1. Pay old depositors with the money from new deposits (Ponzi-style).
2. Use the funds to trade the markets/invest in companies.
3. Invest the deposits in real estate.
4. other ideas ?
