At the time of the listing after the end of ICO, the price often dumps. Why does it happen?
The price dump occurs as airdrop hunters dump their tokens as soon as ICO gets listed on exchanges. Price dump can be avoided in case the airdrop tokens are have some lock period of 2-3 months. Also the development team should have a working product to create token demand and token utilization
I don't think this is the actual reason for the dumping after listing. Airdrop hunters get very little amount of reward that can not reduce the price of the coins. Directly or indirectly social media hunters i mean translation and signature hunter get most the big reward so they involve do that.
