Devs need to be convinced to Add RSK(Smartcontracts) and lightining network(Unsure of Segwit) functionality to the dogecoin blockchain(just like BTC and LTC are doing atm). I believe then DOGE will skyrocket both in Usage and in price.
Question is how many developers are currently involved to make it happen in a reasonable time frame? DOGE needs more active development
at the moment, no dev, they have all canceled their participation to DOGE. You can also find a youtube video with the creator of DOGE saying that he will never continue dev DOGE. make a search on youtube
