First, send out "psychic" prediction tipsheets free of charge to 64,000 people. Half predict a certain stock will go up; the other half predict the same stock will go down.
The next week, send out a new tipsheet only to those 32,000 people who received the tipsheet from last week with the correct tip.
The week thereafter send out your tipsheet to the 16,000 with two weeks of accurate predictions.
After six weeks of this, ask the 1,000 people left for $1000 dollars for a year's subscription to your tipsheet.
Retire.
Retire.
Just make sure it to a country with no extradition treaty. ;-)
