Because they do not have patience and they are still very new to the market. They are likely to be controlled by whales and FOMO. They easily sell their coins with the low price when they see their coins are dumped. And when they see a coin which is pumped, they believe that it is a chance for them to make money so that they decide to buy with a high price
Totally agree. They do not understand well the cryptocurrency market and they just do what other people are doing. They can stop themselves from selling a coin when it is low and buying a coin which is being pumped. god damn. They just want fast profit which can not be accepted
