A common trend I see here in Gambling Discussion are people making threads complaining how they lost money, etc while playing. I bet they were not complaining while they were winning.
There's only on way to prevent gambling going out of hand and it also applies to other areas of life... Create a budget AND stick to it.
Set a monthly limit, a fund for everything entertainment-related. Use that up within a month or not, it gets topped up monthly and that's the only money you can use for gambling.
I have been doing this for years. By making a special budget for gambling, from that moment I did not feel the slightest loss even though I lost in gambling because the budget was indeed provided and prepared to be lost. Then, when I lost the gamble I did not regret it because the lost money did not interfere with other economies.
People used to stick to limits, and beyond some point when they experience good winning automatically their mind move towards a bigger betting. This is where the control must be there, and when one can limit himself even on winning streak will be successful and won't experience massive loss. When it comes to the secure way of gambling it is good to prefer top casinos and sportsbooks as there are people who have won and waiting for days for withdrawal. Even after contacting support team no response.
