I know this is common sense to the majority of people on this forum but I can't stress how important it is to gamble responsibly.
There was a recent case in Australia where a man lost his entire life savings of $400,000+ in a 48 hour gambling spree.
The gambler lost $12,000 in a single bet and then tried to chase that initial amount but ended up losing his life savings.
I am a seasoned and experienced gambler and my one piece of advice to people is to only bet what you can afford to lose otherwise you are setting yourself up for failure.
This is basically the first rule of gambling and the funny thing is that despite the fact that so many people are aware of this rule they still fall victim of the rule. Some gamblers actually go into gambling with the intentions of actually making little profits but the mistakes they make is that they go in with a very huge bankroll and when you start with such bankroll you will definitely lose and losing your money might trigger you to continue playing which at the long run might make you lose lots of money.
