Playing in demo mode is a nice way to enjoy betting but having no chance to lose.
However, i prefer to limit my gambling by setting a fixed amount every time i make a bet.
When i reached it, the game is over for me.
You will get bored easily, playing gambling without real money bet is not exciting and my suggestion is that you should not waste your time and put real money to enjoy gambling but always remember you do put money that you can afford to lose so when you will lose you will not be affected that much.
