Want some free Bitcoin? Who doesn't?! How about burgers and milkshakes? Well, unfortunately, they're not free, but if you head down to the Shake Shack, you could earn yourself a little crypto-cashback when you make a purchase.

That's right; Shake Shack is offering a 15 percent refund on your bill throughout March 2022, paying the difference back to you in Bitcoin.

Grab Some Free Bitcoin at the Shake Shack

You could be forgiven for mistrusting a cryptocurrency giveaway launched by a burger chain.

However, the long and the short of it is, if you head down to your local Shake Shack and pay your bill with a Cash App debit card, known as a Cash Card, you'll receive 15 percent of your bill back as Bitcoin. Now, that's not heaps of money (unless you're going wild on the burgers and shakes), but if you've never owned any Bitcoin or are just up for grabbing a few Sats for free, it's a nice little deal.

Shake Shack CMO Jay Livingston said, "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." Appealing to a younger clientele, those that regularly use Cash App, and those that want some free Bitcoin appears a reasonable approach to boosting engagement across the board.

And although Shake Shack hasn't seen much interest in paying for its burgers and other products using crypto, Livingston realizes that a short-term promotion like this is an easy and relatively low-cost way to gauge demand. After all, who doesn't want some free Bitcoin with their burger?

The limit is 15 percent of your bill, so long as you pay using Cash App's Cash Card. It does appear, however, that Shake Shack's Bitcoin offering is limited to the US, despite the burger chain's presence in countries worldwide.
