It shall never be played with intentions of making money because easily earn money goes easily.
Well, that is tough, imagine you're pretending that you have no intentions of making money but you are playing gambling, and it's not like the house could see through your mind, so what is the point, right?
That's not the main problem, the problem is how can you make easy money in gambling, and the problem with us is that we assume gambling gives easy money where in fact we are the ones who are giving them easy money, its quite the opposite TBH.
I agree, though that is very lame mindset, thinking that you could make money in gambling and using the word "easy" is so inappropriate when we are talking gambling. In my part, I am not a gambler but of course I already tried playing DICE, after few rolls, we are really going to think it that way, that we could make money out of it, then we raise our bets, we doubled it, maybe even tripled, and we lost.
The problem is that we make decisions in the wrong time, because we bet small and we win, we bet big, but we lost, so annoying, and it is because the randomness of the house edge, can't predict it.
