if you lose at gambling you will try it again? will you always gambling your money ?
i think it's very bad idea, eventually you will sell your home to gambling
On the gambling earn only casino owners. If anyone thinks that will earn money, usually is losing. If you like to play, play only for the amount that in case of loss will be no problem for you.
I think it's depending on luck and strategy followed, when talking about gambling. There is some people earn some profits from gambling , they are usually experienced , having good strategies and especially powerful luck. However as you noticed it's advised to play only what we can afford to lose
Maybe there are people that are trying to be "specialist" in gambling, but first thing they don't play online, second thing is that they are trying to cheat..
I hear about guy who can predict more/less number that will come on roulette after few seconds of hearing ball in roulette plate..
