Have you ever increased the amount you normally used in betting just because someone you know won big by betting with a greater amount?
No, I have not because it is stupid to do that and even if I do there's no way I can be lucky like him. Gambling doesn't make it possible for gamblers to win because their friend has won a huge amount. I will end up to lose my bet if I choose to increase the amount I normally stake because I am not sure if to win or not.
But most gamblers will be very affected, that's why casinos often show on their social media when one of their users manages to win a large amount, and as long as that's what actually happened, of course it's not a problem, but when there are casinos who lie because it's not the truth then it is clear that the casino is spreading fake news just to gain more users but a trusted casino will not do that.
If you are not affected by this and stick to the amount of bets you usually make, of course that is a good thing, because that is how we should be because every gambler has a different limit and also we don't know for sure how much the gambler spends until the end win a lot of money.
