US Bitcoin hearings: Regulator tackles virtual currency

New York's Department of Financial Services is to start two days of hearings on the virtual currency, Bitcoin, on Tuesday.
This comes just a day after authorities charged two men in connection with money laundering using, Bitcoin exchanges.
The hearings are more fact-finding in nature, but if New York clears the way for Bitcoin to enter more widespread use, it could be a game-changing moment for digital currencies.
