> In 2002, PayPal was sold, and that pretty much ended the digital currency plan. Instead, PayPal let users link their bank accounts and cards to make payments. This created a bigger dependency on banks.
This doesn't hold up to scrutiny.
Except PayPal wasn't invented by Elon or Peter. It was Elon's company's plan to build the digital bank but they were failing quite spectacularly at it.
They merged with Confinity who'd already built PayPal, had a working prototype, etc.
Elon lasted four months as CEO of PayPal, trying to convert it from Java to ASP until the Board didn't ask him to resign, but fired him, the morning he left on his honeymoon after getting married.
PayPal is a complete red herring there. Elon had no participation in ideas on digital currency there.
