I lost more than I won, I think most of us can share the same story. But the moral here is that caring too much about winnings is a lose-lose strategy. I simply play my favourite games and I pay to play them. If I manage to win, that's great, if not, well, I have paid my time in a casino.
^ That is why it is always against my ego to show my winnings, I felt guilty when showing my winning even though I know that the losses are more than what I have won. It seems I am fooling them by believing the wrong exemption which is thinking that I am a good gambler. If we manage to win, just simply keep it to you because showing victory is not necessary to me.
However, I still respect everyone's decisions, if they wanted to show their winning, that is their life, and let them be. Probably in that way they become release the pain from a huge loss.
More of them replied that winnings should be kept secret, yes, it is a privacy policy for every individual who plays gambling.
