That is how the idea of this topic appeared. I watch others gamble, I watch how the bet, I start to think about betting more than usually. Do you have such feeling also? Do you have a feeling that if others make large bets, that you also must bet large, otherwise you would feel like uncomfortable, or feel like a poor among rich, or something of that kind.
I've done this before and it was really bad.
Why? Because we see a lot of people winning, generally we can only watch or only want to watch the success stories. Of the 1000 people who are playing, we can only see those 10 who are winning, or we purposely ignore the other 9990 who are losing because they are far from our focus of interest.
What is the result of this? When we try to replicate the bets of those winning people, we see that we are hardly part of the 10 successful players we were analyzing, in fact we only increase the amount of the 9990 who usually lose by making the same type of bet.
My advice... observe others, that's good, but also observe the bets of those who lose... also learn from other people's mistakes, not just from victories and after all this, place YOUR BETS based on what you can bet and what you are willing to lose.
