Musk stated in January 2022 that if McDonald's accepted Dogecoin, he would be willing to eat a happy meal on television. A happy meal is a combo for kids that the restaurant chain offers that includes a main dish, a side dish, and a drink.
In reaction to Musk's post, McDonald's prodded Tesla to accept a made-up cryptocurrency called "Grimacecoin." Many people believed that Musk's campaign to convince McDonald's to accept Dogecoin was over after the corny joke, but the most recent Twitter conversations might suggest it is not over yet.
Dogecoin soared by more than 20% last year after Musk's acquisition of Twitter in April last year, causing it to reenter the top 10 cryptocurrencies by market capitalization. Although its price has eased, Dogecoin remains in the top 10, ranking as the 9th-largest cryptocurrency in terms of market valuation.
