91-year-old burger chain hints at Bitcoin partnerships amid crypto surge

It was nearly seven months ago that the popular American fast food chain Steak 'n Shake decided to embrace financial independence and opt for Bitcoin (BTC).

Founded in 1934, Steak 'n Shake is one of the oldest fast food chains that is popular for its steakburgers and milkshakes. The chain has hundreds of stores in the U.S., France, Italy, Portugal, and Monaco.

In May, the 91-year-old burger chain began accepting BTC payments globally via the Lightning Network—a move supported by the likes of Twitter and Block (NYSE: XYZ) co-founder Jack Dorsey.

The chain claimed the pivot helped it save approximately 50% in processing fees within a fortnight due to customers making payments in BTC instead of credit cards.

On Oct. 31, it became the first major U.S. restaurant chain to launch a Bitcoin reserve. Last month, it shared that its same-store sales have hiked by more than 15% and are fuelling the reserve.

It also plans to expand into El Salvador, the Central American country that has been accumulating Bitcoin for years now under the leadership of President Nayib Bukele.
