Hong Kong exchange Bitfinex was hacked and funds were stolen, marking a setback for digital currency Bitcoin. Bitfinex director of community and product development Zane Tackett posted on Reddit that 119,756 Bitcoins had been stolen. “Before the hacking was made public, that number of Bitcoins would have been worth about $72 million,” explains The New York Times. “Now that the currency has slumped, the figure is closer to $65 million.” During its investigation, Bitfinex has stopped all trading, deposits and withdrawals. The security breach is the latest in a series of events that could impact the viability of virtual currency.
