Dogecoin already surpassed BTC in transaction volume. It's destined to be the actual internet money, BTC is internet gold for elitist nerds. In real life no one cares about BTC but i've seen a lot of people being aware of Doge. It's only begining now with the tipdoge app for Facebook, it will go even more viral.
Small increase yearly has no negatives. In fact it helps it to become a currency rather than a store of value.
