Mostly aiming at profit rather than just for fun, However mostly don't end up with any.. The rule is you shouldn't (regardless if it's for fun or profit) gamblle allot of money (any amount you consider allot) since gambling is a game of unequal chances with the house edge... it should just be used with minor sums of money that you are willing to bet with.
That places you more on the playing for fun side dude if you're playing with that mindset. People who have the intention of earning would shell out large amounts of money because that's how you'll earn also. If you have the mindset of playing with an amount you can afford to lose, you're in the safeside and most likely would be playing for entertainment
easy said than done you know , gamble for entertainment are indeed the best way to make you safe.
but it is like bullshit when in the end you can not stick to the rules , the goal as many people have planned. everything changed when you are in the game the atmosphere always bring you into the darkness , i mean you will easy to get so emotional no matter you win or lost you will always want more to make it profitable.
