In my opinion, shitcoin is no volume, useless and no one want to hold it.
For me, I dont wait till a project enters exchange and have no volume before I know that it will end up being a shitcoins, from their whitepaper and their team, I will already know if the product they are proposing is one that will sell to the world at large and something that people will be eager to hold, and secondly check if their team is going to be up to task, if I dont have convention about this, I already define them as shitcoins even before they enter exchanges, and I guess that is why people just take advantage of the first initial pump to take profit and dump them because they do not see any bright future with them.
