Digital currencies like Bitcoin and Dogecoin are created by running computer software that solves complicated math problems. Because of the way Bitcoin was designed, right now it takes expensive specialized equipment to have a chance of getting any. Dogecoin uses a different type of math problem, so you can mine them on your home computer or laptop! You wont mine as many doge with an old laptop as a fancy gaming computer, but who cares? DOGE is DOGE.
