Yes, let's make a guess.
Although the global stock market is more than 70 trillion US dollars. But in the eyes of various financial derivatives, he is a younger brother. The total market value of global financial derivatives is approximately US$1400 trillion. (This is just my estimate, don't take it too seriously) Bitcoin needs a price of 60 million USD/unit. It can be comparable to the global total assets. The upper limit of Bitcoin in the next 100 years may be 60 million USD/unit discounted to the current price.
