This makes me wonder: do casinos actually earn even more during these downturns? After all, some players may gamble to try to "recover" what they lost.
Or is it the other way around? Since players have less money available, do they bet less, and casinos also make less profit?
Me I don't see it as if one of the periods makes the casino make much more money from their customers; maybe they could since gamblers are calculating their bets based on the USD worth and not the volume of Bitcoin, which will make them gain more when customers lose, but they will also spend at the same rate when there is winning, so there is nothing really special when there is a market pump or dump that will push gamblers to gamble more or reduce their gambling activities.
