I suspect this may be the case with most people
either they don't bet with bitcoin at all or they consider USD cost-basis instead of btc when gambling
could be...
Of course, that is why there are many currency options in casinos because not all gamblers want to gamble with bitcoins. Bitcoin whales in gambling seem more inclined to use bitcoin to gamble than other altcoins, I agree with that. But of course, most other gamblers prefer altcoins to bitcoins regardless of the price.
TRX, Doge, USDT, and Ethereum are some of the options I use to gamble, but I'm of course bitcoin is still possible for me to use. In the end it all depends on the preference of each gambler and what currency he prefers the most, but the impact of the decline in the price of bitcoin can be felt by the gamblers.
My average example is using altcoins as a deposit and withdrawal option to make it cheaper, even though I use Bitcoin but not often and this will definitely have an impact on the price drop for them, yes they will feel for me not because I am not the type of deposit much but a little so once down it's not a problem.
Yes, it depends on the preferences that are used, because now there are other options, so many casinos provide it, this makes it easier for other gamblers to choose alternatives coins.
Of course the impact of falling prices will certainly be felt, including me too.
