Also he have been looking for the investors
[LOOKING FOR INVESTOR] CRYPTO GAMBLING CASINO
So it looks like he is now also looking for a buyer for his second casino rather than an "investor". Therefore, he does not care about encouraging people to play, it is just an advertisement of a sale.
It's too early to say this if OP is willing to sell the site again. If he sold before, does not mean that he will sell it again. And to get good money for the casino site, it's important to make it popular first.
Let's wait for OP to respond here on this thread and see his point of view. Let's not speculate things.
