I can't even understand why Doge is still existing, there is nothing in this currency, it will disappear in times
Dogecoin will never die, it was one of the first criptocurrencies here and it was designated just for fun.
That's why it still exists, it is showing to the community that even a ridicolous meme-based coin can be used to buy something online
BTW I think that the price will go up by end of this year (speculation of course)
