Investing money is like gambling , it's either you earn a lot or loss all the profit. However we need to trust and be confident in your decisions to earn more. The more you invest the more you have the chance to earn a lot. In addition try to research first what are the things to remember and background check is necessary.
Investing money incurs risk like gambling, but when you invest the odds are in your favor. There's a big difference.
How can invest can be in our favor? We can't control this thing right, there is always player that control it, like big whale when they win big and run away with a lot of cash and others that play slowly get their money back. There is so many kinds of players right there so how can this be profitable to us?
The expected value is in your favor. Over long periods of time, you're expected to make money because the odds are skewed towards the house, and you're on the side of the house.
It seems that it is way more complicated than that. We have seen quite a few casinos going bust in the past or just running away with the investors money. Given that the house edge nowadays is pretty small, something like 1% or even lower, it is certainly possible for a big whale to strip a casino off of its bankroll or the best part of it. Indeed, there are limits of the max bet which should prevent this from happening, but it happened in the past too with shitty casinos. And this is likely the main cause why many casinos give negative returns to their investors, i.e. due to crappy bankroll management.
