This is not something that has to do with bounty hunters, and mind if I tell you that most bounty campaigns usually only hold few percentage of the total coin or token. In this case I would say this has more to do with the whole market itself not being favorable since it is a bear market and even the bigger investors have more part to play when it comes to driving the market down as only their bonuses alone is enough to do that and most bounty hunters even only get to sell lower than ICO price at times which is always the target of the whales.
