Some people cannot easily decipher when to buy a particular coin, neither o they know how long to hodl and sell. That is why some come to complain that they made a mistake of selling too early or that they fell for FOMO and a coin was dumped on them. Some would even say that had it been they knew, they would have still be hodling.
In my perception, the secret to this is that, we should always try to check for updates on whichever coin we are holding. it is very important.
Updates can be gotten through social media, website and other measures of communication by the team.
