If the gambling sites depend on the value of the cryptocurrency then, it has a big impact on gamblers. But, I think that gambling sites use cryptocurrency which is not converted to USD since we all know that market is very volatile it can go up and down.
I think so. The gambling site will be using fiat value of crypto but i think that it will always give direct impact to the gamblers. The dump was also giving very very big impact in context we are talking about crypto gamblers but i think that those gamblers are always gambling their money directly to the platform rather than keeping their money in the gambling site.
