Well, there is the adsense modality, which is the most popular and the one that sells the most on Google, and it is also accepted because I have Always seen ads that are from exchanges that have to do with crypto and having Crypto is there in the middle. of bitcoin, then again you have to know how to advertise and that is a way of marketing, of course, but of course it is more Expensive and I think there May be a way to do it that Way , for me it has always been the best , but I think it's because Google has changed many Adsense policies, Because you can even Monetize with Natural traffic, many have resorted to cheating and I think that's why they are so Demanding now.
AdSense may not allow for casino marketing since I believe google doesn't support casinos advertisement but I have seen a few cryptocurrency excahges that got promoted and advertised on ads display, although casinos always fine they way into marketing themselves even though there have been some level of limitations to that public, there have been alot of restriction to Gambling promotions in most countries reason being that gambling is termed as a dangerous activities that could affects the individual financial life.
Without a doubt it is what you say, it is a dangerous activity, but it is something that will always be there, you cannot cover the sun with a finger, that is why when we look for Ways to do Things better, we always come across ways to promote the casino, for example, I have seen that I am browsing Google and if adsense advertising appears, in this case I think it Depends on the country in question, the exchanges, the Brokers, I Always find advertising from them , and from the Casinos crypto too, Now if I am on the Internet with my PC or laptop it is more common for casino sites to appear, so in this order of ideas , it seems to me that Google may allow it in some areas, otherwise it Will be a bug.
