Overstock (OSTK) CEO Patrick Byrne is a pioneer in bitcoin. But even he is having trouble pinpointing the reason behind bitcoin's plunge on Friday.
"Well, I don't know if it's a flash crash, a trading issue or the new ability of Wall Street to short," Byrne told TheStreet when asked about the mysterious drop.
Overstock was the first retailer to accept bitcoin in 2014.
