Me too down some 100$ and still in process to earn it back.
I think you should just forget it by thinking spent money for fun or entertainment because if we try to recover back our loses than we may end up losing more. So just play some times for fun and if your lucky than surely you will win back your money but don't try to chase the winnings.
That's right, the more we think to recover our looses in the game, is the more we gave ourselves to be lose again and again. So the better way for this concern is to stay away with it. At least win or lose it doesn't matter at all.
True, the worst thing to do is chasing winnings in gambling. Only luck is needed to win money in gambling, so there is no need to try so hard to recover your losses. If you try to recover at least, you can save those coins and think whatever your lost is donated to someone. Concentrate on earning back those losses from some other investments and never try from gambling again.
