My life experience shows that not everything that happens in your life should be told to someone. There are things of a personal nature, and if you don’t want to talk about them, then that’s your own business. But there are some cases when you cannot remain silent about your passion for gambling, if, for example, a person gets married, then his spouse should know about such things, over time he will find out anyway, because God makes everything secret obvious, and this is a serious issue that can affect the entire family's well-being
Of course not every stranger should not that you gamble. You dont even have to tell it yourself to others. But my idea is not to keep it in secret on purpose. There is no need to do it when nobody is at home only. If asked what your are doing or if you gamble - answer honestly. There is no need to have a special secret bank account to gamble with that money only (but it might help to those who cant control their finances). There is no need to clean browsing history straight after gambling and etc. If asked by family of friends - answer honestly. They wont judge, and they dont have right to judge you.
Concealing our gambling habits is only effective and acknowledged, for safeguarding non gamblers. Not everyone is capable of discussing gambling without being subjected to gambling someday, secretly, or openly. On other notes, gamblers are free and not outlaws. There'll be no need to hide their gambling habits. I prefer letting people know, over bottling it up. When nobody is aware, gambling awareness won't be achieved. A player can lose his awareness, but a close friend can help revive him. Condemnation and arguments instantly start, some friends cutting us out and adding salt to our game, letting others know that we gamble. These factors have led most gamblers to focus on the game, and not discuss it with anybody.
It's a self-determination, players own their life and time here. I don't think convincing anyone on what to do, when they didn't ask for our help, is a wasted effort. That is, a player who is comfortable concealing his gambling habit, isn't doing any wrong. What is most crucial is staying responsive. I've never seen where both factors keeping it a secret or not, changed the gambling behavior of the gambler. Both types of players can get addicted. Aside from addiction, third-party contributions don't count. Everyone has their purpose for any action they commit. Nobody controls the impulse of being bullied with our money.
