I agree with you, it is better to hide gambling activities, because many people have a bad view of gambling, so if other people know that we are gambling, it can cause conflict which might become a problem, or could become the subject of gossip. Although this depends on the country which allows gambling or not, in my opinion it is not appropriate for gambling to be publicized.
Luck will never come consecutively at the same time, each gambler will only have one chance and when this opportunity cannot be taken advantage of then they will only suffer much bigger losses.
Awareness that they must be able to take advantage of the winnings they have obtained is often forgotten and in the minds of gamblers they are too ambitious for big and truly satisfying results.
It just that things like this are not experiences that can be learned from but instead become bad habits that are always done.
We have to be able to take good care of ourselves because in social or social environment, even in group of friends, no one knows what the future will be like if everyone knows about the gambling we do.
All of this is also for our own good while in the gambling industry and to be able to avoid sentiment and bad impacts that could occur.
