Apple cofounder Steve Wozniak said he was scammed out of $70,000 in bitcoin

Apple cofounder Steve Wozniak admitted in a talk that he was scammed out of several bitcoins by a scammer using a common technique.

The Economic Times reports that Wozniak spoke at the newspaper's global business summit, and during his on-stage appearance he discussed cryptocurrency.

"The blockchain identifies who has bitcoins, Wozniak said, "that doesn't mean there can't be fraud though."

"I had seven bitcoins stolen from me through fraud. 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."

Wozniak's seven missing bitcoins equate to around $74,000 (£53,000) in lost money. That likely won't be a concern for Wozniak, though, who is worth around $100 million (£71 million), according to CNBC.

Wozniak said that he sold all but one of his bitcoins. "I didn't want to watch the price everyday … I sold all except one. It was enough to experiment," he said.
