Altcoins are just distractions from Bitcoin. They usually have no real value except as a mining pump and dump profit. What was the last time anyone had a serious thought about Dogecoins being a world-wide accepted currency?
Well there was that one time they sponsored a nascar driver, but I have a feeling they never really expected it to go anywhere.
I think the "doge" memes died pretty quickly, and dogecoin died along with it.
