Many of the traditional gambling platforms are now turning to get their customers online which is what we are seeing these days. I have seen making local gambling platforms that now have their website when people can gamble online so their customers can have the opportunity to gamble at their own comfort. The era of traditional gambling casinos is fading out and I know that many cities in the world that is know for gambling activities would soon be dry with limited gamblers going there to place bets because they can noe play their favorite games at their own convenience without stepping out of their comfort zone.
Those gambling sites which is land-based and turn online can be sustainable and would be able to earn a lot of money as they can attract the attention of their customer/audience. But those who are not turned into online gambling sites they can't sustain for the long run and they must have to lose their audience/customer.
