I am one among them who visit gambling sites or online casinos regularly or at least twice a week , even after losing hard earned money and also knowing the fact that gambling is not an earning option. But I have came across these reasons from my experience as to why people can't stay away from gambling despite losing everytime.
* Players treat gambling as a fun activity and losing some part of their income to casinos doesn't bother them much.
* Players place bets with smaller amounts like $1 and win , but when they bet higher amounts like $100 for a 2x multiplier , they lose. This happens because some casinos do manipulate the results and make people lose when they bet higher amounts , the site owners would have known the player's betting pattern and accordingly rig the games like dice , mines. ( Note - I am not telling all the casinos are manipulating the bets , there are some legit casino sites as well).
* Players usually continue playing in casinos only because of their varied bonuses offered for wagering.
According to my experience , one should always stay away from gambling , and also should not encourage others to gamble , because the result of gambling is not good , though there are some people who make money from Sports betting , with calculated risks.
