Management's fault:
They tend to be greedy at one point of time and starts thinking that if they distribute the bounty to the hunters they will dump it anyway nad the value of token will crash down and they dealy the distribution meanwhile the bounty hunters start writing bad about the project and there were instances that the genuine bounty projects were termed as scam for this issue.
Who are you actually referring to managements fault? Is it manager or the developer? In my experience its always the decision of the developer or owner of the project when to distribute tokens because they are also the one who send the token to bounty participants and its not mostly the reason why value of token crash after distribution of bounty no this is not true, one reason I can see is the developer itself dumping huge amount of token greed is the main reason why price is always crashed upon listing on exchange.
