We have been in the crypto gambling space since 2018 we can clearly see that when the market goes down, the activity at the crypto casinos goes up. 
Why do you think this is happening?
This can happen for various reasons, whether someone invests in crypto or uses money for gambling, the intention in all cases is to win something big and strengthen their financial position. So when the market is down, many traders convert their investments into stable coins. And at that time they can use casino sites as their source of income. Everyone says that they use gambling only for fun, but here their intention is to win and earn money from it. Perhaps something like this can happen for these reasons. I am not sure but I can guess something like thisWhy do you think this is happening?
Well, every gambler's purpose is to win. Yeah, there's the fun side while playing the game, but I think no one wants to lose. We all want to win at least a bit of money and maybe use that to have more fun.
There are no facts and proofs that the crypto casino goes up when the market is down. I don't think it's happening for a reason, it might just be a coincidence. The only possible reason that I see is that traders don't want to do anything with the market while it's down, and so they just play around, gambling or whatever entertainment they can get.
