Fed's Yellen says Congress should look at Bitcoin regulation
Japan-based bitcoin exchange Mt. Gox went dark on Tuesday, leaving customers unable to access their accounts. Experts have warned they might not have much recourse to recover their money.
"The Fed doesn't have authority with regard to bitcoin but it certainly would be appropriate, I think, for Congress to ask questions about what the right legal structure would be for virtual currencies that involve nontraditional players," she said during a Senate committee hearing.
