I was scrolling through instagram and I came across this story
https://www.instagram.com/reel/DNqQIlNg99m/?igsh=cGJ5NGlveGY2ZzV3This is a story of a poor man who played a sport betting game with little money but the potential win was big according to the story he was gifted an opportunity to cash in on a good amount that to his financial status is more than good for him but he decided not to and ended up with nothing.
First thing I do after placing a bet is see my potential win as not mine, those figures written as your potential win are dream money it’s never yours I don’t care if your last game is Real Madrid against a team in the fourth division of Iran’s league.
The imagination of already seeing your potential win as true can make one forget their financial status as it did to the man in the story.
Your financial status is more essential than your potential win in deciding if you should cash out or not.
Sometimes the reason why gamblers used to see there potential winning as there's is purely because of over confidence. They fail to understand that gambling is a game of luck and as such it will be wrong for any gambler to treat there potential winning as there's. However, I have seen scenarios were the reverse of what you actually explained happen.
