So at this point I decided to bring it here to know or see different views from different intellects here on why do some people hide just to gamble or if it is the best way to gamble ?.
Honestly, I didn't get the essence that I could get from the thread you posted. especially, if you refer to the title of this thread. Well, it's like this, actually we can answer it simply, in general this is something that is normal if there are many people who prefer to gamble in a quiet place. in this context, referring to your post. it's not like they're hiding "in the broadest sense of the word." It could be that they just avoid the crowds, without anything that makes the games or gambling they do attract a lot of attention in general, or that might even make them noisy. The proof is, you can approach them and even interact. The point is, I don't know where you are, whether gambling is legal or not in your country.
To be sure, I can't answer correctly. because, in essence, I don't know for sure why they did it as you said. There are many factors that cause this, one of which is as I said above. Apart from that, there are many people who really like to gamble secretly for various reasons from online gambling. The most common reason is perhaps it makes them feel comfortable or avoids people around them not knowing. In your case, the gambling you are talking about is based on real gambling, people gathered together in a hidden place. so there is nothing special about what we are discussing in this thread "sorry", because for me the answer is simple as I said.
