A lot will say its for profit for sure. For me, the fun doesn' exist while you are playing. I always feel very nervous while I'm at it because I know it will disappear in a matter of seconds. The fun only exists after you win your target price.
That is true, everyone wants the profit gambling offers. But don't get so nervous, it's not good for your health, control your temper while playing and don't put too much money on it, so you can stay calm.
And if you think it's not giving you profit, stop playing or you will continue losing money and it's not good for your health as you are playing only for profit.
Actually, when we use our money and our money on the risk than definitely we feel nervousness and excitement. It is normal attitude of life. But being a gambler we should dare ourself and control our nervousness.
How can you resist this nervousness when you could lose so much money. The feeling is the addictive feeling that keeps us going and could be considered fun so I vote fun.
