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.
Yes, all players are in disadvantage (from mathematical point of view) but true is the luck plays significant role as well.
Nevertheless from the long term view the investors are on the profiting side.
BTW you can control this thing by closing active invests. Notice some player is constantly winning? so close them before he gets more lucky (or adjust kelly accordingly) ... but from my experience it's not the best tactics .... IMO most of winners are just temporary ... sooner or later the greed overhelms, they try to win more and lose everything ... thats what gambling is all about)
