However, this is gambling not trading or holding. I know crypto is volatility, but for a gambling site most people will not hold any money/fund/crypto in a long time on a casino site. As usual, gambler will always gamble the money If win some money they will withdraw instantly.
I don't think stored the money for gambling with only a few hour is gonna effected his money from crypto volatility.
Most of the Blackjack.fun whale players didn’t do a short term gambling as you described. They are storing funds there and bet in regular basis to get the hourly, daily and weekly reward. I doubt too that other whale do the same thing you described because they already have a lot of money and most of them just spend there excess money for gambling, Only shrimp gamble o casual gambler done that deposit and withdraw after few hours of playing.
You can apply this example on different games like sports betting, Whales have no choice than o wait for there bet to settled before they can withdraw, In that case they will surely affected by volatility. I site his example since this Casino will have an upcoming sports betting feature.
