This is a ponzi scheme. First, someone who no one has ever heard of before announces that he has discovered a way to make money
Second, the individual claims that a particular market provides unexploited arbitrage opportunities. Something is selling too low
The individual who sells the Ponzi scheme makes money by siphoning off a large share of the money coming in. In other words, he does not make the investment
How is the government printing money that doesn't exist so that it can lend it to itself and 'bolster the economy' not a ponzi scheme?
