SHORT STORY: Pick something of value, make bets on the future value of "something", add contract & you have a derivative.
Banks make massive profits on derivatives, and when the bubble bursts chances are the tax payer will end up with the bill.
Since there is literally no economist in the world that knows exactly how the derivative money flows or how the system works, while derivatives are traded in microseconds by computers, we really don't know what will trigger the crash, or when it will happen, but considering the global financial crisis this system is in for tough times, that will be catastrophic for the world financial system since the 9 largest banks shown below hold a total of $228.72 trillion in Derivatives - Approximately 3 times the entire world economy. No government in world has money for this bailout.
