I agree and also I do not agree with you, bounty hunters only get a small portion of the amount of coins that are usually only 1%, 2 or 3. Even if half of the bounty hunters sell their tokens, it's only 0.5% of the total supply and this should not affect the normal market. If the price falls because of the bounty hunters, then this is a problem of the volume of market, but not of bounty hunters.
Even so I suggest that bounty hunters sell coins they get according to ICO prices or higher, there's nothing wrong with being patient for a while to get more benefits.
