The FTX bankruptcy affected the cryptocurrency price and marker, which means it also affected all the people dependent on FTX to make transactions. A gambler whose money is stocked in FTX cannot make maximum gambling as they used to do. When one aspect of the crypto is bleeding it affects other aspect that is related to it. That is why we keep hoping that one man doesn't cause a problem for all of us.
Never keep significant funds on the exchange - this will save you from many troubles, but this is repeated every time, people think that this will not affect them and continue to lose their money. It is likely that some of the players who have lost their money will pay less attention to gambling as they have lost money, but overall this should have a strong impact.
