Nothing says 2021 like dogecoin, a dog-themed cryptocurrency that has recently skyrocketed in value, thanks in part to the support of Elon Musk and other celebrities. For a time it was the 10th largest cryptocurrency. Dogecoin finished 2020 at less than half a penny per DOGE, according to CoinDesk’s dogecoin price index. It now trades at or above 5 cents, putting its year-to-date returns at around 1,000%.
