Maybe time will tell, but we can currently see that Satoshi Nakamoto's wealth is increasing or decreasing automatically, one example of this is that a few days ago, when the price of Bitcoin touched ATH in October, he probably became the ninth richest person in the world but the negative impact on the market is now at work, causing Bitcoin to undergo a huge correction, so it may have fallen from that position.
The future of Bitcoin is still unknown, so if Bitcoin touches a million dollars in the future, maybe Satoshi will be the richest person in the world in the future just by holding the BTC he owns.
This can only happen if the assets of today's top billionaires like Elon, Jeff Bezos or Larry Ellison do not increase. But I doubt it, their wealth is even growing very rapidly thanks to the development of the technology sector.
It's hard to know exactly when bitcoin will hit 1 million and make Satoshi a trillion dollar man. But honestly, I think with the need for AI technology, electric cars and the world moving towards digitalization as it is today. Elon and other billionaires will soon join the $1 trillion club.
Do you think that the wealth of today's top billionaires, Elon Musk or Jeff Bezos, will not increase? Of course, companies like Elon Musk's Tesla and SpaceX will continue to grow in scope, and their assets and growth will continue to increase over time. At the same time, the wealth of the inventor of Bitcoin will also increase, in fact the main thing is that the number of Bitcoins stored by Satoshi is like a secret. Moreover, there may be a specific calculation of the wealth of Larry Ellison and Elon mentioned here, these indicators are enough for them to be identified as billionaires.
I have seen before that the inventor of Bitcoin will be worth more than Warren Buffett. Bitcoin hit $126k in October so a slight bullish sentiment was needed from there, meaning if Bitcoin had reached $136,000, Satoshi would definitely have surpassed Warren Buffett.
