Thanks for your comment @sugah, It never crossed my mind to think about people with gambling addiction, but in this case I don't think that can be a problem because it depends on your gaming skills to be able to beat your opponent to win the bet.

Normally people with addiction to gambling are related to games that are determined by luck, in this case is very different.

But I am very grateful for what you have said because it makes me consider new aspects that I had overlooked.
