There are only two ways to no longer obtain frustrations from gambling, the first one is to stop gambling, it can be hard if you like it but it is a sure way to do it, the second one is to stop having expectations of winning when you gamble, gamble only because you find it entertaining and not because you are looking for a profit.
Add to it that you should not look for a smart way in gambling, because whatever way you are doing but if you will stay there for a longer time.
It will only give you a frustration, the longer we stay to a gambling site the more we are prone to lose all our bitcoin.
Just don't stay that long into a gambling site and you will be fine.
I guess this is a smart way.
