Several businesses in Detroit are beginning to accept bitcoin as a payment option, according to a report by Detroit Free Press. For example, David Ayyash's ChickPea in the D restaurant in downtown Detroit recently began accepting bitcoin.

"If people ask for a new way to spend their money, we’ll be more than willing to attract them," Ayyash said in an interview with Detroit Free Press. Ayyash uses a tablet POS to generate a code for the customer wishing to pay with a bitcoin wallet.

Other Detroit restaurants such as the Bronx Deli, Urban Bean Coffee and Papa Romano's Pizza are also accepting bitcoin. March Zuccato, owner of the Bronx Deli, also operates a bitcoin ATM in his Farmington Hills location. Zuccato is optimistic about the future of bitcoin and has not converted any of the virtual currency into fiat currency.

"I actually haven’t cashed any out," he said. "I'm hopeful that it's going to climb back up."
