No, it is also the reason why I chose to use crypto or Bitcoin when I am gambling, I don't want to know the current value of my bets so that I could continue to gamble without the pressure of knowing how much I am risking.
Even if you are gambling with bitcoin or other crypto, some casinos—in fact, the majority of them—will covert the amount to USDT equivalent immediately you place your bet, so if that happens, you will still see the amount you are risking in each of your bets.
And if the value is not being displayed, don't you think that might make you even spend more than you could have ever budgeted to gamble with that very day since you don't know the worth? Rather, you are using the currency amount to place your bet; to me, it's more risky that way.
Regardless if you deposit with bitcoin or USDT, the thing there is that, casino's have their market displayed in dollars, even if you deposit and stake in bitcoin or in other acceptable coins on that casino, the value is going to be calibrated in USD and when you want to withdraw your winning from the casino, you must withdraw using the same coin you deposit a d amber with, let say if you deposit bitcoin and vet with bitcoin even if you see dollars display, when you want to withdraw you must still withdraw using you primary currency which is bitcoin at that moment.
So if left for you as a gambler to use your senses to accumulate and calculate what you are betting with and regardless of what the price of bitcoin should be at the moment, I don't think that should be a big problem since at that point, you already have all things in place that will make you remain in steady position.
