I think its because you can easily doubling your money on gambling but the risk is you also can easily lose your money on gambling. I think gambling is makes more addicting when you win much money on gambling and it's make you want gambling more.
which makes gambling so addictive is not only when we win the advantage, but if we lose any money we would gamble again to regain the lost.
Yeah I agree with you whatever results you get on gambling than likely you would go back to gamble again. I do not know what magic is used by the gambling site for players to keep play gambling. but if you gamble you definitely feel very enjoy and exciting right ?
It is not the magic itself man, we are the only making ourselves addicted to gambling and that is for one reason which is "greed", with that we never get contented if we lose or win.
