There are two main reasons, why a token price is falling after the first listing. First of all, bounty hunters that have earned some tokens are likely to sell them, this causes dumps. Secondly, team members are unable to make new people buy their coins because of the lack of marketing and poor management.
I think you guys need to stop this argument of bounty hunters dumping their coins, how many projects release their tokens to bounty hunters even before listing on exchanges? To me what is happening is that people are becoming wise, one there is not strong fundamentals to support a project, they dump and move, even if BNB tokens start to show sign of weakness people will start dumping
