I made a profit, but not 20 times as much as the contract, but only several times. Team 1 is likely to go bankrupt because the bank that paid the bet was affected by the financial crisis. If it goes bankrupt, the bank can't pay the bet, and all the money is lost, I will be scared to find someone to sell it at a low price. In the end, 30 million will become more than 80 million, which is ok .. Team 2 went bankrupt because its parent company is going bankrupt, and the foundation is under the parent company JPMorgan Chase. If it goes bankrupt and is liquidated, their foundation will be counted as a part of Morgan Company and will be used to pay off debts. Therefore, they must sell the contract, dissolve the foundation and get the fund commission before the parent company files for bankruptcy, and then pursue the responsibility. With the foundation gone, they can keep the money. So the actual income can't be 20 times as written in the contract, and finally they earned hundreds of millions. Team 3, one person, the bank earned the insurance premium of short contracts in the early stage. He got a piece of it. Later, the contract explosion had nothing to do with him, because he left early and earned tens of millions. Team 4, the doctor who first discovered this situation, Juanjuan, should have made a big profit by watching that whiteboard.
