Some people who keep their gambling a secret, in my opinion, are people who don't want to take risks, because I myself do it like that, I don't want anything that could trigger conflict with the gambling I do. Therefore, keeping the gambling you do a secret, including the winnings you get, is good.
Keeping your gambling habit equals not wanting to take risks? Not necessarily so. People who keep their gambling habits a secrets perhaps don’t want their affairs out and about in the public. Risks has nothing to do with keeping your affairs private as you could always and at anytime, take same huge risks privately as others publicly do without anyone knowing about it.
I’m a big fan of keeping your affairs private, only sharing to those friends and family close enough and who deserve to have certain information about your activities.
"didn't want the affair to become public." In my opinion, that's the same as not wanting to take risks, but that's not a problem because everyone has different perceptions, so I also respect what you say. Some gamblers who keep their gambling secret so as not to reveal it to the public definitely have their own reasons, whether it's because Indeed, gambling is prohibited in one country or another, but what is clear in my opinion is to keep our gambling activities a secret, if we publish the gambling activities that we do, there will definitely be people who are not happy with what we do.
I myself don't publish the gambling that I do, I only show it to certain people who I really trust, one of which is my own friend who also likes gambling. and I kept it a secret from my family, because my family really doesn't like gambling. Even so, there are definitely people who like to publicize their gambling, because in my environment there are people like that, and I don't even like it, why should something like this be shown off proudly.
