ELI5: How did Bitcoin go from being nothing into becoming something so expensive?
gpt
The simplest explanation is that people wanted it.

Value is just a representation of how much someone wants something, and how much they're willing to pay to have it. When Bitcoin was first invented, nobody really saw a use for it, nobody wanted it, so it was dirt-cheap. As people kept talking about it, and the philosophy behind it grew more widespread, people wanted it more, and started charging a higher price.
