I think having such an incompetent person at the job could actually materialize the crash all the Bitcoin maniacs were talking about for so long.
To be fair, I do not think there is any reason to believe that Yellen is any less competent then Bernanke or Greenspan. The global financial system is headed for another major disruption, regardless of what Yellen does.
When most countries ban Bitcoin and only US allows it as bubbles are how the financial system operates, it cannot be a global system. It's already banned in Vietnam, Russia, and partially in China and India. You understand this is a huge portion of the world's population in these countries. Any negative news from China will lead to a huge crash. There's no Mt.Gox anymore and Bitstamp closely follows the movements of Huobi and BTC-e follows Bitstamp, so, you get my point. Big investors already have lost and if they lose further, they will cut their loses and the crash will be imminent and permanent this time.
If the US doesn't *attempt* to ban Bitcoin it will be a global system regardless of what other countries have done. Other countries will be forced to revert their stance at the risk of losing opportunity. If China were pro-Bitcoin, the US would need to be pro-Bitcoin to compete... It only takes 1 world power to ensure the success of Bitcoin, after that it's just a matter of time.
