In 2021, Dogecoin (CRYPTO: DOGE) firmly established itself as one of the world's most popular cryptocurrencies, thanks in large part to Elon Musk's famous Doge-to-the-moon Twitter Inc (NYSE:TWTR) campaign, which kept millions of investors on the edge of their seats (and their portfolios) for weeks while the coin made huge gains.
Though the dust has settled on the Doge hype train, Musk and co-creator Billy Markus often engage each other on Twitter, saying nothing but positive things about the potential utility of the coin and its solidification as a "real" currency.
