Transak on the other hand are just straight up removing themselves from the gambling industry altogether.
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.
Gambler are not only limited to funding there account through any of those payment gateway providers, they have other means of acquiring crypto which they want to use for there gambling activities. All they just need do is either buy from any merchant either through DEX P2P or use centralized exchange which have P2P option or which ever platform that permits direct deposit, those purchased coins can then be transferred to the betting account. There is nothing too big about the monopay payment gateway rather than the gambling sites trying to make things easier for there customers so anything making those payment gateway to stop offering there service to casinos will definitely have something to do with regulation as both parties are gaining from the service they provide to each other.
