I like to believe that top casinos do, compared to CEX exchanges where they get commissions on fees, the casinos are beating players and high rollers and they yield millions, see the comparison of the number of exchanges compared to the number of casinos.
Entrepreneurs know where they are going to put their money and it's where people are intentionally putting all their money at risk which is the casinos, the figures online can't lie, the online gambling industry is a multi-billion industry and it keeps growing by profit and by users.
