If you must invest in Dogecoin among other cryptocurrencies, you must put what you can afford to lose. CoinFlip, which operates the largest network of Bitcoin ATM's, announced in early March that Dogecoin can be bought in cash at its 1,800 locations nationwide as the useful source cryptocurrency continues to become more accepted by companies. Apart from exchanges which let you trade Dogecoin, you can in theory use Dogecoin to make purchases. Once you buy DOGE on an exchange, it's similar to owning any other cryptocurrency: You can either keep your coins on the exchange, or transfer them to your own wallet software — an official wallet is offered on the project's website, dogecoin.com. If you hadn’t heard about Dogecoin before, you definitely heard of it after Tesla CEO Elon Musk and rapper Snoop Dogg decided to send out a few tweets over a weekend in 2021: resulting in a sudden top 10 ranks by market value for Dogecoin.
