And is it worth trying to recreate one? I would imagine it's already too saturated. Either way, I was mostly curious about how much these guys actually make (margin-wise). If anyone had some insight on this, I'd love to hear.
Just like there are many altcoin in crypto market so there's nothing bad in creating a gambling site if you all the requirement despite it been saturated already and I want you to know that every business have it own time of losses because the rules of business setting is to accept debt some time. With that side, yes gambling sites make good money.
Yes, having a gambling site I feel is very good and profitable, because there are many people who will be interested in playing. From the gambling site that you have you will get a good profit and I am sure about that, besides you can get income from every visitor who comes, on the gambling site you will also get lots of benefits because there are many players in it. There are many gambling sites in the crypto world, I'm sure you know about that, and there are many that have stood for a long time and still survive today, in contrast to the altc that many of them(altc) don't have a decent exchange rate on the market if the altc is lacking supporters or enthusiasts. So making and owning a gambling site I'm sure it's profitable.
