But let's look at this phenomenon from the other side. As you know, any movement of funds has 2 sides: what is a gain for someone is a loss for another person. Those means that for one are a thing that changes life in a positive direction, for another are a thing that changes life in a bad way, because the other side of winning is losing.
That's the dark side of gambling. Not everyone can win any money, there's always someone who will losw their money while the others are winning. It's part of the risk and the consequence of gambling where they will face the risk or the chance or having the possibility to win huge amount of money with also the chance of losing it.
However, this shouldn't be something we should think of because gambling is considered as one of the most pick activity for entertainment and of course to try making money. It's not for those people who would hesitate just because someone might lose money. Remember that if you gamble, some other people is winning. It is a vice versa scenario and probably that other person will not think how much money you lose the same as you are thinking.
