OP's behavior seems like he's a novice. So we should not neglect him. I applaud him. If his gambling history can be observed for some days, then his real issue will be clear. OP may have beaten DuelBits today but gambling is not over, there are unlimited days left. His position during those days can be clearly understood. Perhaps after a certain period of time it will be seen that Dualbits has beaten him.
I can't blame him because that might be his very first of its kind actually and what else do you expect, having first experience with winning on a casino will be like a magic to some because they just wanted to have the opportunity of hoe it feels to make a win, some just as I've earlier said, except he makes this within the shortest period of his experience in gambling which means he never loose as to that extent before then we consider that a winning, bit on a real sense canna gambler actually make winning in gambling than loosing? except on rare occasions.
Maybe he is a novice but we can't forget that we were beginners without experience. What @OP and all of us have to remember is that maybe today we can win a lot at one particular casino site but another day, there is no guarantee we can win a lot more at that casino site and maybe we will lose. And what often happens is that when we start to lose, we will deposit more money, thinking it is a small loss. But if he's a beginner, it's really a fortune that comes for him because not everyone can get it.
i just wish OP realized that winning is an occasional occurrence and not constant while he make effective use of the little won by him, but am sure he will love to continue gambling all because of either in anticipation for another bigger win than the first or to continue deriving satisfaction with pleasure time in gambling, he will definitely want to continue but as long as he's not too conscious or desperate for another winning i think he will be fine, there might be another visit of luck on his side, but the more one is desperate for a winning the more the gambler looses.
