Gamble only what you can afford to lose. that’s the key to avoiding unnecessary (High) risk.
Losing more than you can handle comes with serious consequences, especially gambling addiction, and once you reach that point, it’s hard to get out. That’s why prevention is important. Have discipline and don’t be greedy as that way, you can still enjoy gambling, even when you lose.
That notwithstanding, if anyone is finding it difficult to control it's gambling habits and you've realized that gambling is affecting you negatively,I think it's high time to advice and encourage yourself to retrace yourself backwards.You could do away with setting strict restrictions on yourself but if managing and minimizing the risks involved is becoming hectic,then consider a long term break as a gambler.
