You can think of it this way. The money earned in futures is the money lost by others. The money earned by those who buy up is lost by those who sell short. Markets are always like this. If you go to a crowded place to drive the subway and compete with the big mouth next door, the money you earn from the subway is the money earned by the big mouth next door. If Dazui goes out of business, isn't that why you earn too much in the subway?

Speaking of gambling, gambling is ubiquitous in the commercial economy. For example, when Mengniu was short of funds, it used international capital to inject capital, but international capital signed a gambling agreement with Mengniu to be on the safe side. In this way, if the compound annual growth rate of Mengniu after accepting venture capital is less than 50% in the next three years, Mengniu will pay more than 70 million shares or equivalent cash to venture capitalists. If it exceeds 50%, the venture capitalist will pay the same amount to Mengniu. . . But who knows if Mengniu can do it? When venture capitalists see that he can do it, they will inject capital. If Mengniu loses the bet, venture capital can become a shareholder of Mengniu. If Mengniu loses, venture capital can also get a lot of investment income. . . . That is beside the point. . .
