In my opinion gambling becomes addiction because of if i have been losing it make me curious and that is make me addiction of gambling.
It drags me to gamble too, but also important reason why i and other gamblers gamble is because they can earn a lot of money this way even if it's risky
Gambling is addictive mentally. The worst thing for a beginner is to win a large amount of money. Later, even when losing, is expecting that the next big win comes easily and work out their losses. However, usually this does not happen and people are getting only more addicted.
Most of the times its the 4th reason because you see if someone was rich why would they gamble ? I think the best way to understand its addiction is that : Losses gives addiction, winning gives addiction then how exactly would we leave gambling ? So its the loosing and winning that makes us addictive.
