.You plan out a simple Investment Brokerage Ponzi Scheme that pays investors 10% interest per month.
2. You get a few investors to pony up $1000 to earn a 10% interest in a month.
3. Those investors spread the word, and your scheme starts to gather steam.
Result: After a few suckers are caught up in the scheme, word spreads that your investment is a scam. The cops catch up to you and not only is the money gone, but you are off to the slammer!

I love it...
