The rest, I agree to you that they really have no utility and they're made just as dogecoin for trading because we recently entered in the bull run.
I remember that even Doge is created as meme there are traders who use this coin to transfer their fund between exchange as the fees is really low it's been used as good alternative to avoid paying high transaction fees., And also, gamblers use this coin with same intention having low fees if I remember it correctly.
Before the hypes of Musk, Doge already went their serves as pump and dump asset, we still seen interest from traders and investors those
who are willing to play with this coin.
Aside from the influenced of Elon Musk, very possible to see another hypes when the entire market start to pumped high.
Many of us have considered it as a meme coin but during high fees of bitcoin and ethereum, we've chosen to use dogecoin as a means of transfer because it's really helpful.
