Even if we would reach the mass adoption, what place would take Doge? I can understand that cryptos like ETH, EOS or NEO would be used for payments, other altcoins for other industries like real estate, travelling and so on, but in my opinion there is no place for Doge in the real world.
Dogecoin isn't going to be the next "big thing"(top coin/altcoin)in the cryptocurrency network, but that doesn't mean they should not try to grow and develop, at least for those who are already holders of the coin and those who use it for day trading.
There are people who use and hold Dogecoin, as well as enjoy whatever benefits(advantages) they gain from it, it would only be comforting for them, if the developers of the coin have plans for it, plans to get listed on better exchanges, plans that would reflect on the price of the coin. There are so many altcoins, and yes Dogecoin may not hold any admirable position among them, but if they are trying then it's a good sign.
