Yes, people always loose in the long run, If you won one day then you will definitely loose next few days. If you calculate at the end then the money you have loosed during the gambling will more than what you have earned. So I would like to suggest that just play for fun and do not get addicted towards gambling.
Nope it wont be that way either. I ever gamble and earn 0.1 per day. I can hold it until next week after that I lose then I stop and continue on the next day and I keep on winning again. Actually this is depends on your luck and your mind too. When you are going to stop on continue it. So playing for fun will not affect to gamble. Playing for fun will only wasting your money
