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
That would be ok if someone took over, but nobody seems to want to do it, so Doge is just a meme unfortunately. I quite liked the coin, but it doesn't really offer anything anymore in face of all the competition.
And it's perhaps impossible to change what once made it so strong in a trustworthy way. As you said it is just a meme and it is like a stigma and nobody would really believe DOGE could compete with the big ones on a technical level. And ultimately, that is the truth for now (and might remain forever).
