when it comes to modern gambling, money is the most important thing and that's right, no argument can break it.
but if you refer to culture, especially gambling culture, it is not only money that is at stake. There is a role in testing luck, for example, the Chinese gambling culture with its mahjong or pai gow, cohesiveness in the group (family) when playing gambling in culture.
no exception to the traditional gambling culture that exists in my country, not only money is the betting medium, there are many unique things that not many people understand the implied meaning in it.
