I guess there are many superstitions in different cultures, especially about money.
The greed for money creates many superstitions.
The older generation in my place, especially the Chinese, believes that you must not give away your rice cooker, pots and pans to others.
If you give away the rice cooker, pots and pans away to others, you are giving them a way to make a living, and you will become poorer.
There are many superstitions about winnings in casinos too.
For example, they will advise you to buy sweets that kids love.
They believe that children ghosts live in the casino, and they will stop you from winning unless you give them sweets to eat.
I doubt they are right or that they are experts. They definitely are not billionaires or millionaires.
Despite all their beliefs and adherence to the superstitious beliefs, they are not rich.
