Bellevue, Washington-based Expedia just announced it will start accepting bitcoin for hotel bookings. The online travel site is embracing the volatile, virtual currency on what it calls a "test-and-learn" basis.

Effective as of Wednesday, the digital currency will be a payment option, but only for hotel bookings on the company's U.S. site.

Seattle has just become home to the first bitcoin ATM in the U.S. Northwest.

Here's a surprising fact: the largest bitcoin mine in North America is located on the outskirts of Wenatchee, Washington.

It's not a mine in the traditional sense. In these mines, you won't have helmets, lamps or pickaxes, and there's no danger of cave in. In this case, the mine consists of two warehouses that have been converted into a data center.

University of Puget Sound

As a 2007 alum of University of Puget Sound, Nicolas Cary has already established himself. The 28-year-old is the CEO of Blockchain, which runs the world's most popular digital wallet for bitcoin, a virtual currency.

But now he's making headlines for his bitcoin contribution to UPS. Cary has electronically transferred just over 14.5 bitcoins to the university, which was then exchanged into $10,000 actual U.S. dollars. It's reportedly the first donation of its kind to a U.S. college or university.

Have you been swept up in bitcoin mania?

Bitcoins purchased at the beginning of this year were valued at $13.50. As of Dec. 9, they were trading at close to $900. That’s a rise of more than 6000 percent!

Many folks are eyeing the virtual currency as an easy way to make huge profits. But KPLU financial commentator Greg Heberlein urges caution. Bitcoin prices may very well continue their march into the stratosphere. Or the bubble could burst.
