What are you talking about? The halving is done already and we are waiting for the 4th halving now. What date of writing did you do and you just post this now?
Hey! With the 3rd halving just around the corner and Bitcoin trading at about $9,200 at the time of writing, the price may break past the $10,000 mark once again in the weeks or months following [a lot of polls in regards to that here as well]
There's currently a sideways market before and after halving. I don't think there's a direct correlation towards halving and gambling itself but only towards what it could do with the Bitcoin price. But as you can see, nothing big has happened with the price except for the dump from 9k to 8k.
