"I had seven bitcoins stolen from me through fraud," Wozniak said at the Times' Global Business Summit. "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."
At today's price of around $10,200 a bitcoin, Wozniak's stolen cryptocurrency are worth roughly $71,400.
Bitcoin is up several hundred percent from less than $1,000 early last year. It is the first application of blockchain technology, which eliminates the need for a third party such as a bank by creating a near-instant, permanent and secure record of transactions.
The American inventor remains a supporter of the cryptocurrency, which he initially bought at $700 each as an experiment, according to The Times.
