Hello guys, I hope you all have a nice day.

in this year a lot of ICO projects that make Bounty Campaign, When ICO successful and has been listed in the market, Most bounty hunter immediately sell all coins they have.
This causes the price of a token to fall even away from the ICO price.
Have you taken advantage of this moment, guys? I think its moment is a good time to buy a token with a cheap price. how about you?
very happy to hear your experience about that.

I don't think there is any opportunity whatsoever... if you take an example and do some calculations, you might be able to reframe your question.
Let's say a bounty campaign has 50k to offer as bounty project work. Now how many people you would think we'll participate in the bounty? May be 2k, or may be 5k in total. Or may be say 500 only. If we consider 500 hunters for a bounty campaign worth 50,000, then each gets $100 on average. Oxide, the amount per hunter can be more or less, but for argument sale I am just dividing 50,000/500 to get $100 per hunter.
Now your argument that price of coin falls because of bounty hunters is wrong beef of the following reasons.
1. There has to be a coordinate selling among all bounty hunters
2. $100/hunter is not good enough to move the market
