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.
For this reason, casinos initially came up with chips - it is psychologically easier for a person to part with a chip than with a bill of real money. Now it's time for cryptocurrencies and, above all, bitcoin - a significant part of the players perceive it as real money and a great opportunity in the future, so they use either altcoins or stablecoins.
