When asked, “How do you make your money,” Satoshi can honestly reply, “The old-fashioned way. I print it myself.” While that’s not exactly true, he did invent his own currency. Bitcoin.
The enigmatic creator of the first and most popular cryptocurrency is believed to hold over $400 million worth of the digital money and, indeed, they are nothing but the fruit of his imagination.
You could consider bitcoins to be a consensually shared hallucination, though really they function based on the same principle that regular money does: They have value because and only because the people who trade in them agree that they have value. They appear on your computer seemingly from the ether, the product of a mining program running on a PC. The only work done to create them being opening and running said program. The only byproduct being heat, the only expense being electricity.
It is believed that Satoshi invented Bitcoins out of frustration with the difficulty of sending wire transfers overseas to purchase model trains. (first ive heard of this) He imagined an internet-native, border-free currency and from his imagination he created bitcoins. He started mining them right away and when they skyrocketed in value his net worth did as well. You could say he literally dreamed up his fortune.
