I think it's a real shame that new providers won't have access to reputable fiat to crypto on-ramps, it creates an uneven playing field as the big guys get treated differently.
I don't think there is something wrong with staying with what you already know how they are or doing business with outlets that you have spent longtime business atmosphere with. Moreover, it is reasonable to say that these fiat payment gateways are only trying to be safe in the government where they are operating to avoid bringing in new casinos that have some illicit deals and money laundered through them. However, I don't think new casinos should bother their head on fiat payment because quite a hand full of gamblers prefer privacy and are transacting more of cryptocurrency. I can't imagine linking my fiat bank account to a casino when I could just transfer crypto, that is the point.
That is pretty much it. It's sad that new gambling sites won't have much flexibility with introducing fiat payments but it won't impact them much.
Since most gamblers prefer crypto deposits the gambling sites can continue without any fiat payments.
Besides that, gamblers who want to do fiat payments can deposit fiat on other platforms, exchange to crypto and then transfer it to the gambling site.
