The gambling is an instant play and it's not the same like an investment. If you are playing the game and you will get two results. Win or lose. That's why dump means nothing for the gamblers.
This is quite different compared when someone was gambling in the casino.
In truth, aside from what was said, other gamblers are bitcoin holders, even though the price of bitcoin is down at the moment, there are still others who still use BTC to bet on games, especially if they know that they will win. He will always accumulate bitcoin and it will be in his favor as a holder. But of course if you are just a typical crypto gambler, and he wants to stay in the game for a long time and he also wants to get lucky, he will choose another crypto to use such as dogecoin or TRX not bitcoin.
Meanwhile, if there is any gambler who doesn't care about the falling value of bitcoin in the market, I am sure that this kind of gambler is a gambling addict. The only thing they think about is gambling and gambling and always thinking about making a lot of money because they always rely on luck...
