Steve Wozniak, the co-founder of Apple who is widely considered to be a tech genius, made a rudimentary and expensive mistake recently, MarketWatchreports.
"I had seven bitcoins stolen from me through fraud," Wozniak said at the Times’ Global Business Summit on Monday. "Somebody bought them from me online through a credit card and they cancelled the credit card payment. It was that easy. And it was from a stolen credit card number so you can never get it back."
