I feel same here mate, most gamblers forget that gambling is risk and based on the uncertainty its smart that we play safe with it, although you can't really be totally safe cause any money you wager is considered gone untill the game is concluded but we must always remember not to give to much to a particular game, there should be a risk reward ratio to what we are doing and we should play safe with gambling.
Gambling is not safe and there is always a possibility to lose money but people are not ready to accept the risk involved in gambling as they believe that gambling can make them rich.
Gambling will only be safe if you give little time to it and more time to another job which gives you regular income so in such situations you will not lose so much money because less you gamble less you will lose.
If you find out the fact that your loss percentage is greater and you are not earning money then don't try to recover your money because in the recovery process you will lose more than previous loss because the outcomes of gambling are totally concerned with uncertainty.
