Let's just hope that people don't think like that of using gambling to make money because it's really hard to do. Most people will only experience defeat rather than win, let alone big wins. Indeed, certain people can really get big wins, but not many. And that is what makes online casino sites increasingly popular on the internet because they can attract more people, especially by using attractive promotions coupled with giving bonuses.
I wouldn't use "hard" as a description for gambling really, more like unknown, neither easy nor hard since you can't exactly figure out whether you're going to win or not in a gamble. Ofc it tends to fall more toward the losing side since the house always wins, but you get my point I think. Unfortunately since it's "unknown", it ends up looking more attractive to most people as well hence why they're going for it.
It's true. We won't know whether we will win or not in gambling and can only keep playing if we are curious about the win. But we must remember that the house will always win, no matter how hard we try, because that is their place of business. If several people can win a lot, it is still smaller than the casino's winnings. Those people know but they try anyway because it will attract many people to keep returning to the casino. Moreover, they get tempted by the casino's promotions, so they return to the casino.
