How rich is Satoshi Nakamoto?

I've always been fascinated by the mysterious figure of Satoshi Nakamoto, the creator of Bitcoin. He's essentially the father of cryptocurrencies, and his influence on the global financial system is immeasurable. But what I really want to know is, how rich is he? Does he sit on a fortune beyond comprehension, or is he living a humble life, content with his creation? Given the astronomical value of Bitcoin today, I can't imagine he's struggling financially. But is he a multibillionaire, or even a trillionaire? Or did he simply create Bitcoin for the love of the technology and never intended to become wealthy from it? I'm just curious, because if he is as rich as I suspect, he must be one of the most secretive and successful entrepreneurs in history.
