Having self control and setting limitations is easier said than done. There will always be moments when you won't think rationally anymore and will place crazy bets with much higher amounts than you would normally do. Happens to a lot of players, including me. Only thing that helps for me is keeping the balance very low.
As far as I know, some casinos even have a feature that allows them to restrict access to gambling if a player loses a significant amount of money both per day and month. This is a very useful feature, especially for those players who are unable to control themselves. To be honest, I didn’t even pay attention to whether there is a similar function on the Betfury website.
I don't believe in self-exclusion! Why would anyone do that when simple logging out would do the job?! It's either you want to stop gambling and you find some other things to occupy your mind, and you force yourself to not even think about gambling... if you really wish to quit gambling! Who thinks that self-exclusion helps by itself is in delusion, most of those guys who do that simply create new accounts and do everything over and over again. Of course, they blame all others for their "addiction". I simply can't buy that!
As Baby said, the only thing that helps us gamblers not to jump directly into the fire is "normal" balance, something we can always afford to lose without any consequences! It's on us to have control over our actions and to know that things we do come with consequences. Who doesn't respect that will feel how hot fire can be...
