The Wall Street Journal reported that customers will receive 15% of their purchase back in the form of Bitcoin on any Shake Shack purchase made with Cash Card — a debit card available to Cash App users — and by buying items via Cash Boost, a rewards program available to Cash Card members.

“You’re always trying to place your bets on those things that truly will be meaningful and not waste resources on the ones that won’t,” Jay Livingston, Shake Shack chief marketing officer, told The Wall Street Journal. “If we just started taking crypto right now at our kiosk, it would have very low adoption,” he added. “But through someone like Cash App, who’s been promoting it, you will get some more people that want it and that also want to learn.”

In addition, about half of crypto buyers are interested in earning cryptocurrency instead of points, the study notes, with 51% interested in earning crypto rewards, compared to 56% interested in earning cashback instead of points.

Shake Shack seems to be taking this trend on board.

“Not a bit, just more coin. You heard right, now ’til March 15th, select Cash Card by @CashApp holders will be able to get their 15% Boost reward in the form of $BTC instead of USD. We’re taking Shack to the moon,” the company tweeted March 4.
