Promoting gambling is not a bad thing to me because I myself is a gambler. I have been playing gambling on a low key for more than 6 years now and I do win and lose but to me what really matters is having control over yourself on when you are gambling.
And that is what self control is.having played for 6 years and yet betting in low keys?thats rare because the longer we played the higher profit we demand so we basically go for high bets in time
No matter he emphasis on Self-control, there are still player who would never obey the rule because of greed and then they would come back to pour their frustration on casino sites after making loses. Like you mentioned been content with little winnings, many will never be content, since gambling is their only source of income and this is really wrong.
Gambling is not supposed to be a source of income and if at all you choose to make it a source of income, just learn to avoid greed and there will surely be record of more wins than loses for your games.
