Funny money? Think again. There are lots of places -- and ways -- you can spend bitcoins. Here's are a few.
At CheapAir.com, the decision to accept Bitcoin started the way it usually does: with a customer asking, "Can I pay in bitcoins?"
The company representative didn't know what to do, but CEO Jeff Klee eventually heard about the request. They started accepting them last week have already received more than $6,800 in bitcoins sales.
Travelers can't benefit from the highly private nature usually associated with the electronic currency. While the purchaser of a flight on CheapAir can remain anonymous, the traveler cannot.
"I think this is the kind of thing that'll gain more momentum over time," Klee said. "As more companies accept Bitcoin, it will snowball."
