The first step in buying Dogecoin with Robinhood is to open a Robinhood account and fill in all the required documentation. Then you should verify your account and fund your account. With your Robinhood account fully funded, now you can initiate a buy order for Dogecoin. You can also withdraw Dogecoin from Robinhood. Robinhood is a great app but still has certain flaws. The good news is, there are plenty of other platforms that offer Dogecoin, such as Gate.io, Binance and Uphold.
