The early year it was created and launched in is also advantageous: it was launched at an early age of Blockchain, right when memes literally exploded all over the web so it does not surprise me at all that it still survives many years later. Furthermore.. it is cheap, fast, the fees are absolutely meaningless.. only if strong development continued, it might have been placed higher in the ranks today.
But being a joke cryptocurrency, it probably would not be a very sane move to make it a legitimate, widely-adopted one, albeit in case of a real cooperation with Musk it would not be too far-fetched.
It might jump and surprise everyone though.
It certainly has a very cyclic and unusual graph for a cryptocurrency and many expect a new cycle to begin soon. The latest Doge predictions were not very accurate though, the new cycle was supposed to begin months ago but it seems to be on a constant delay.
