Sad fact that new traders think trade is only buy and sell and hold. When coins that they hold not give good value for long time, they don't have any other strategies to get out from loss then make decision to cut loss and retired from trading.
well, it's natural when they think like that. basically, trading does look like buying and selling. however, they did it with their will. the most important thing about it is finding information before trading. without doing that, of course panic sell will occur.
