Bitcoin now 2% of revenue at Chicago cafe

A Chicago cafe recently installed the city's first bitcoin ATM. Cassava Bread, a gluten-free café, has been accepting bitcoin for roughly four months and the digital currency makes up 1 percent to 2 percent of total revenue.

"It doesn't really cost anything. In fact, it's cheaper than most credit cards," said Cassava Bread's owner, Jorge Flores. "That's more than we take in Discover Card, and that's a national credit card." Story
