In the US, Shake Shack restaurants have chosen bitcoin to test whether the eatery’s customers are receptive to this digital currency.

With its promotion, lasting just a few days, the fast-food chain will simultaneously manage to find out if consumers are keen on using mobile payment services.

Here, customers have to use CashApp to pay for their burgers and fries in order to receive the equivalent of 15% of their order in bitcoin.

“Our bitcoin rewards test on Cash App is an exciting way for us to learn about our guests and how they want to use cryptocurrency,” Shake Shack marketing director Jay Livingston told the US media outlet Nation’s Restaurant News, emphasising a desire to personalise the consumer experience.

At the end of 2021, Burger King too tested the power of cryptocurrency as a reward to build customer loyalty.

This time, the retailer was able to assess consumer interest in crypto by integrating Dogecoin, as well as Ethereum and bitcoin into the rewards offer.

Members of BK’s loyalty program had to spend five dollars via the fast-food chain’s app to have a chance of enriching their cryptocurrency wallet.

Fast food restaurants have been testing the integration of cryptocurrency into their business models for quite some time.

In 2019, Burger King’s German restaurants approved bitcoin as a payment method. The home of the Whopper even launched its own cryptocurrency in Russia in 2017, named the Whoppercoin. There, too, the digital currency appeared as a reward: all you had to do was place an order to be offered Whoppercoin.
