Which is the No 1 money game in the world?

I'm curious, which do you believe is the number one money game in the world today? Are we talking about traditional financial markets like stocks, bonds, and commodities? Or perhaps it's the realm of cryptocurrency, with its rapid growth and innovative technologies? Or could it be something entirely different, like real estate, venture capital, or even the world of online gambling? I'm eager to hear your thoughts on what you consider to be the top money game globally.
