This is obviously crossing the concept of gambling. Just gamble to make fun and just bet on the amount you can afford to lose. Once used up, stop gambling and go home immediately. With that, you will never encounter problems in gambling.
They are betting on things which arent really talking basically on money but on other bets that they are making. It is quite that evident that it is also really just that for fun.
It is really that good to gamble out together with your friends or co-workers into your free times. As long you arent that compromising your daily budget or money
then i dont see anything wrong with this. It is really just that we are just that too judgmental into those people who do engage to gambling.
