It seem that almost all ICOs that get listed on exchanges usually plunge in price soon afterwards. Are bounty hunters responsible or is it as a result of the general bearish market condition?
Bounty hunters plays a role on the dumps you are seeing. However, I think the reason for this is the buyers themselves. They know that bounty hunters will dump their coins/tokens immediately after they receive their payment so buyers bid lower than the ICO price. Historically, many coins/tokens jumps back after bounty dump.
