If they don't release something new and cool, I think it will be at the same price. It doesn't have nothing innovative and maybe the new coins, that are going on this day (Like Ethereum, Waves, Ethereum Classic, Steem, etc) will take dogecoin place, well it's happening, DogeCoin it's on the rank number 11, according to CoinMarketCap.
The inflation of the coin is going slowly high, but I think maybe there might be a little pumps, but it will continuing going down. The only think i see to this coin is the age and population.
