Then why is he still not a billionaire?
Mila Kunis called Uber "the worst idea ever." Ashton Kutcher and his partner invested $500,000 in the company. By 2016, that stake was worth roughly $50 million, according to Forbes.
In the video below, Kunis tells Stephen Colbert why she tried to talk her future husband out of investments like these.
Her family left Soviet Ukraine in 1991, when she was seven. In Los Angeles, her father, a trained engineer, worked as a cab driver.
Kutcher described Uber as a cab company where anyone could drive. He offered to order her a ride so she could try it. "You're going to put me in a car with a stranger? What is wrong with you?"
Then he told her about Bitcoin. She asked, "Is it FDIC insured?". Kutcher replied: "No. That's the point. It's not."
"I think this is a horrible idea," she recalled telling him. His response: "Cool, we're investing it."
At the beginning of 2013, Bitcoin traded below $100. During the week of her interview in April 2021, it traded above $50,000.
Kunis says she now books accommodation through Airbnb and takes Uber everywhere. "I've never been happier to be wrong."
