The price of Bitcoin surpassed $1,000 again after Zynga Inc. said it would start accepting the virtual currency for some of its online social games, citing wider use of the digital money.
Bitcoins, which exist as software and aren’t controlled by any country or banking authority, surged to about $1,045 on the Mt.Gox online exchange, one of several markets where they are traded for dollars, euros and other currencies.
