For me,it's mainly for fun,no seriousness included.Because i know,that gambling will not make me have an positive income,greed will always tempt us to spend more money till we broke.
Just play a luck based game and leave it all to fate.
If you can position gambling just for fun then greed will not tempt us to bet high, we know that income from gambling will be lost in gambling too so just enjoy gambling just for fun with low capital.
