It only takes a little bitcoin to enjoy a big sandwich at one Subway location.
An Allentown, Pa. shop has made history of sorts by becoming one of only two Subways in the world—the other is in Moscow—to accept bitcoin for payment.
Bitcoin is a digital currency created by a network of online operators that has been soaring in value recently, with one unit now worth more than $500.
Adam Welsh was so excited about the opportunity to use bitcoin to chow down at one of the ubiquitous hoagie shop's locations that the York, Pa. resident made the approximately 90-mile drive just to take part, according to a report in the (Easton) Express-Times.

"They're definitely pioneers in doing it," the 23-year-old Welsh told the paper. "I think it's awesome. I feel like once the word gets out, it could really spread like wildfire."
Store owner Shapan Shah said folks have come from all over, including New York and New Jersey, just to use their bitcoin to make purchases.
With the soaring value of bitcoins due to speculators in the market, the problem with using it today is that it could be worth much more tomorrow.
In Welsh's instance, his $12.35 purchase cost him 0.04 bitcoin. On Monday, it would have cost just 0.02307, according to bitcoinexchangerate.org.
