emotions are a natural feeling, because of course no one is happy when they lose money, but in gambling losing money is a clear risk that will definitely happen, and when they gamble it is the same as they have lost their money intentionally, not accidentally. that's why we must be able to allocate a certain amount of money with a statement that we are willing to lose it so as not to get carried away by the atmosphere. someone who is not ready to lose money will feel emotional when the gambling they do ends in defeat, and that is a mistake that often happens.
emotions tend to make thinking unclear and tend to make us take actions that are decided carelessly. avoiding emotions that can occur depends on ourselves, so doing research is an important thing to consider.
