This one is only for fast money and i have one for patient money. fast: bet your friend $5 that he/she won't give you $10. if he/she does give you the money, you will have to pay $5, but still get $10. if they don't give you money, you still get $5. this will probably only work once. for the patient type, buy a bond. wait until the value goes up. this could take awhile.
