Well I love gambling, but I am tired of hearing complaints by the losers in gambling, who said they have put all their money into gambling to get much more, but in the end they lost it, then blame the gambling site owner and stated the gambling site is not fair 
Limiting your money to gamble is a good way, so the risk could be lower

Then if that's the case much better to just let those gamblers gambled. No words , suggestions or comments here can stop them unless they will experience it to their own self the burden of being lost.
