A question for those people who suggested to use XRP, or TRX, or other altcoins instead of Bitcoin. If there was an easy and good UI/UX solution built to send and receive Bitcoin through the Lightning Network, would you choose that instead of the altcoin? Did you actually buy the altcoin because it's simply faster?
There are probably only two reasons I can think of why someone would prefer using altcoins over the lightning network to deposit/withdraw to/from a casino or any other crypto service. The first reason is that he never used the lightning network before and doesn't realise how easy it is to make a payment with it especially with the advancement of the wallet softwares supporting it.
The second reason is that he has all his coins stored on centralized exchanges where the fees to withdraw altcoins are way cheaper than the fees to withdraw bitcoin.
I believe there's one reason that holds more truth than your two reasons. It's plebs like us actually LOVE to invest/trade/speculate in altcoins/shitcoins, and every bull cycle brings newbies, looking for "the next Bitcoin". I was one of those plebs who day-traded, lost his lost savings/learned the HARD WAY. But it's partly because of the lack of education about Bitcoin and what it sets it above the shitcoins, and part human nature of curiousity.
