With the current online gambling has become the choice of many people to gamble including those whose countries prohibit gambling, Conflicts can occur in a group of people who gamble with different results. I'm sure there have been cases where some people gamble with different results and people who experience defeat are upset and then take it out on other people who gamble the same but manage to win.
You are right, online gambling is safer because our privacy is maintained unless we ourselves leak it to others about the gambling we do online. In addition, online gambling has another advantage where we can play it according to our wishes to play it wherever and this is one of the conveniences in my opinion.
The freedom of having the option to gamble at anytime and anywhere is something the online casinos has given us too that we cannot forget in a haste already, then the security that comes with the privacy when you have mega wins and all you have to do is withdraw to your account except if you disclose to others, no one gets to know, all of that combined gives us an advantage we didn't get at the physical gambling house.
