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.
Of course, the impact will be felt by the gamblers but it really won't matter to them at all because they would still gamble despite the market's situation now. Some gambler says that they aren't doing the activities often now because of the situation but that's just the minority because the majority doesn't budge with the price movement as they will always choose altcoins that aren't making huge movements, just like what I always do.
