It seems to me that the price drop after the listing is due to the fact that no one believes in the value of coins in the future, since every investor, as well as the Bounty Hunter, only plans to make money on a certain project, and few people worry about the future of this company. Recently, a lot of companies have announced that their tokens that they issued do not have a practical purpose. Therefore, everyone is trying to get rid of these coins as soon as possible.
Any investor or bounty hunter can check that the project is good or not because if the project is not working well, they will tend to sell more. Most people in this market are interested in profits because any project will have its own risks and we should not trust their promises. I think if you can ensure profits in that project, you will not have to worry too much and can completely leave that project if you want.
Some projects are intended to be scam from the beginning and if you are lucky to sell at a good price, it will be very beneficial to you. Of course the lucky rate is only 2% in this market and should not be expected too much for bad projects.
