As a gambler, we will surely want to choose a coin that is much cheaper and its volatility wouldn't surely hurt us that much if it will suddenly inclines or declines, and surely wouldn't mind thinking if they could influence such coin movement. I believe that on average gamblers are not using bitcoins upon betting in their favorite sports book or casino game.
This is why people preferred doge before all of this Elon stuff happened. We loved Doge for the fact that it was cheap, fast, and usually not volatile. It was accepted in most casinos, and it was like a joke money where you throw in 5k of it, 10k of it whatever, if you are rich enough then millions.
This is why it was such a good thing and now because of Elon Musk it became something that is a bit more volatile and because of that it became a bit more problematic. Of course there are still some coins which are low in price and you could send them with little cost, but they became not so great because of all the volatility in the market these days hence why not used.
Dogecoin is classified as sh*tcoin because it almost has no utility but gambler/investor still loves to spend it, especially when it comes to gambling activities as their prices don't move that much. I agree that Elon Musk has changed dogecoin but there are so many people who have been successful enough to duplicate Elon's actions before dogecoin dipped again. But that's fine, as a gambler, we always find ways what specific coin is good for gambling purposes.
