Gambling with crypto us like gambling on top of gambling. By the time ypu win or lose it could actually hurt or help you. Meaning if you lost but the coin went down anyway in price then ypu really didn't lose that much value, so long as ypu buy the same amount back at the lower price. But on the flip side if ypu win but the price goes down ypu increase your stack of coins but not fiat value of that stack. I don't mind gambling with either to be honest. It's small enough to not impact my life one way or another.
The important thing for me is to win at bets and have fun, learning how to position myself better. Betting is a 50/50 risk thing anyway, so it doesn't matter to me whether I win or lose, because I bet very little anyway, and I still don't have the confidence to bet larger amounts.
Regarding the question in this topic, I always use crypto like Bitcoin and Litecoin to fund my casino account, as it is faster, cheaper and more private. I prefer casinos that support crypto, I've never used stablecoins to fund my accounts or fiat. For me, the casino accepting crypto is more important, as it is an additional use for my coins.
Even more so now that Bitcoin fees are cheap, anyway, in cases of congestion in the mempool, just use a cheaper coin for this, like Litecoin.
