Cointelegraph spoke to a German Subway franchise owner and the CEO of a Switzerland-based Bitcoin company, Lipa, to understand whether Subways across Europe might start accepting Bitcoin.

The world’s largest franchise by number of restaurants is trialing Bitcoin payments at three Subways in Germany’s capital, Berlin. Subway first experimented with Bitcoin almost 13 years ago in Moscow, Russia.

Over the past few months, Daniel Hinze, the Berlin Subway franchise owner, recorded over 120 Bitcoin transactions. In an interview with Cointelegraph, Hinze explained his desire “to help Bitcoin become money.”
