Dogecoin has been used primarily as a tipping system on Reddit and Twitter to reward the creation or sharing of quality content. You can get tipped Dogecoin by participating in a community that uses the digital currency, or you can get your Dogecoin from a Dogecoin faucet. A Dogecoin faucet is a website that will give you a small amount of Dogecoin for free as an introduction to the currency, so that you can begin interacting in Dogecoin communities.
