It is not always easy for some people to stop chasing losses, that is the problem. This exists in crypto gambling world as well, some people make excessive losses and they end up continue that losses with more gambling yet they can't stop because they believe "eventually my luck will turn". Same goes for traders, they find some coins and they think it will 100x somehow, didn't before they invested but for some reason it will right after they invest, it keeps going down and they sometimes even buy in more because they think if it was going up when they got, it will certainly go up now that it is even lower.
There is really no way we could stop those people, they will do whatever they think is right for them and they will find a way to lose even more money than they already lost.
So true, very valid points. This is the more reason why if I'm not investing in a coin for very long term, but for short term or mid term trading purpose, I must use stop limit at the next support level. Some people do not think about the negative aspect of buying a coin especially newbie traders, they just believe any coin with hype for instance will pump hard. However, if I'm investing long term on a coin, I invest what I can afford to lose.
