You can purchase dogecoin in a few simple steps. First, you'll need to find a cryptocurrency exchange or investment platform that offers the coin. After that, you'll need to enter in the dogecoin ticker (DOGE), decide how much you'd like to invest, choose your payment method, and place your order. Once purchased, your dogecoin balance transfers to your platform's built-in crypto wallet. But most exchanges also give you the option to transfer your crypto balance to an external hot wallet or cold wallet. Hot wallets rely on digital storage, while cold wallets utilize offline, hardware devices.
