The point is not that he is very wealthy and has more affordability, but that he has the opportunity to sell you his probability rights at a better price. As in the case at the beginning of this article, Las Vegas is willing to buy away the protagonist's probability rights for $150000 because the casino can easily increase the price of the probability rights and transfer them. The person who bought your "button" probability rights may be a probability rights wholesaler. For example, he acquired thousands of "button" probability weights like yours, so the law of large numbers helped him achieve stable positive expectations. So he is not afraid of volatility and does not mind the gains and losses of one city, one pool. He is a casino and a platform. So, the essence of a platform is to have probability weight. Of course, he can also break down your entire probability weight into many small probability weights according to "6, 7, 8" above, and use small investments and high odds as attractive factors to turn a probability weight into countless small probability weights with almost zero winning probability for buyers.【Google,guessing competition,Ball game,】
