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.
