All peoples in around the world don't have the same ideas and skills at all the sector because some of the peoples here earning a lot from the online casino and some of peoples making world largest and biggest exchanges here. So it is also very difficult to say for me which sector is more profitable cex, casino or the digital banks.
But for me casino business is more complicated maintenance and I think not all people can handle the difficulties in this business but for cex I think it is much easier management here and large people are also attached with so may be they make more profit from the casinos as we can see already Binance.
