i dont think there are any, gambling is created for people to lose money
thats true, in my opinion the gambling is meant to be for people to lose their money and it is a bad thing in my opinion, there are no safe ways to play gambling
It's not like every gambler is doomed to lose, casions have profit because they have an edge and a big number of bets to utilize that edge. For every loser there is almost the same, but slightly smaller number of winners.
Right gambling doens't mean that all of us will be able to lose. Of course there were few gamblers like pros are gaining their profits and most likely the casinos or gambling owners will be the greatest benefactors.
