^This means that no one risking their money on the ready-to-made casino but I think not unless you are a good developer too that you can able to check first on your own. That is why casino owners did not want to buy a ready-made gambling casino because the potential of scams ios very high, they prefer to find a great developer that can build a casino from scratch into a successful gambling casino. The fear of getting scammed or having trouble in the future will push them not to buy a casino like this.
However, I dont know what happen to the OP about his gambling casino and I want to know an update on him and his selling casino.
Buying a business is always a very complicated process, and this is because you need to know a lot about the business in question to know if the valuation that you are being given is appropriate or not, in my opinion the OP is trying to sell his casino for too much money as he is asking 300% more than the yearly profits the casino itself can give, and that is assuming the profits remain flat, which is impossible to guarantee as gamblers can get tired of a casino really quickly if it does not present new games and bonuses.
