1) Being social

Bitcoin ATMs? That's right. The virtual currency can now be exchanged for U.S. dollars at machines all over the world, including the one in the above tweet by @dogecoinisgreat. It's located in the Pioneer Place mall in Portland.

"Users of the Pioneer Place ATM can now trade the virtual currency for U.S. dollars—in $20 and $100 bills," a Willamette Week report on the machine states.

The ATM is not that rare. Check out all of these Twitter pictures taken of similar machines. There's one in London pictured along with others in Canada and Bucharest.

Willamette Week reports the first Bitcoin ATM was installed in October 2013 in Vancouver.
