When your goal is only to gamble for fun, that is better and the chance for you to become addicted can be lesser because you will be contented on every results that you are getting but if you play for profit, you are sometimes not contented when you are winning. In your head you need to continue because there might be more wins waiting for you. When losing, you also want to deposit again because you want to recover. This doesn't end.
Exactly
That's why I do believe that the people who are actually gambling to make some profits or if they are praying to god for some kind of miracle while holding the lottery ticket these people might get addicted in some way before they can realize that they have lost all, they try and win it back which makes them loose even more money.
Honestly the only way to gamble should be for fun, games like blackjack is something else that's like the one where your skills might count as well and such games you can definitely make an exception but one must realize that gambling is a*game* not a source of income..
