Dogecoin is a strange project. Initially, it had nothing special and I think people loved it because of the funny design. It was easier to mine Dogecoin than Bitcoin or Litecoin at that time and I think it was another driver of the coin's popularity. In recent years the dynamics of Dogecoin were good for traders — when other cryptocoins were going down, paradoxically Dogecoin's price was going up. It saved some traders' funds.
