People gamble for all kinds of reasons
Some love the adrenalin rush and can be addicted to losing as much as winning(that's the scary part, and they usually have no control once they start)
Some people are recreational gamblers and just do it for a little entertainment(they mostly have things under control though anyone can lose control)
that's all depends on your mood, if you feel you have enough money on your wallet to backup your lose you will lose your control. but if you need that money just for double it, you will blind for a while then
