There is no problem for Doge, even many companies, legislators and well-known people have no problem with Doge,
in fact, like Elon Musk and big companies want Doge, so why should we doubt him for investment?
I'm sure Doge will be one of the altcoins that are like Bitcoin.
saying it will be like bitcoin is a stretch, main motivation doge could increase was because elon shill, without it, it has shown stagnant price that until elon shill for it again, it will also increase.
doge is good for gambling but certainly not as good as bitcoin though.
