No not really. I can assure you that not all bounty hunters will dump their bounties once it will hit the exchange because I for one will hold my bounties until it is the right time to sell them. Maybe you are right that we need to understand the project itself because if that project is good then probably that coin have a high probability to go to the moon and you will regret later why you dump it early, it is a common experience here in crypto world.
no not all bounty hunters dump there coins but some do it with fear to aviod them being on lost but i think some great project now use to hold there token until when the markets is in good shape before the sell which is the best decision.
