I gamble a lot on sports sites. I once put 100$ on 3 matches to double my bankroll. Its the most secure play on sports sites.The first two matches were correct and i was optimist about winning. The team it supposed to win easely playef with second team players. They tied in the last minute and i was really mad. That was by far my worse moment in gambling.
Yeah it is really bad, I've experienced it too three or four times.
