Dogecoin, originally created as a joke in 2013 by software engineers Billy Markus and JacksonoUy Palmer, gained unexpected popularity over the years. Billy Markus, the co-creator of Dogecoin, sold all of this Dogecoin holdings in 2015,longe before the cryptocurrency saw its massive price surge in 2021. At the time, Markus wasn't convinced that Dogecoin would amount to much and sold his coins to buy a used Honda Civic. He stepped away from the crypto space because he found the community's toxicity overwhelming and never intended for the coin to become a serious investment vehicle.
