Sometimes, i just smile when i see bounty hunters dump their coins. I have seen situations where after they might have dumped their coins, within within 24-48 hours, it begins to rise again.
Whenever a coin lists and bounty hunters are paid, it is always an opportunity for investors to buy from them cheaply.
Most times, i wait for opportunities like this, despite being a bounty hunter too. I acquire more and hold. Then i sell high later.
There are times bounty hunters a lured by investors into selling cheaply on DEX, before any official listing.
Although, this might not be applicable to all coins, but it happens to most.
Talking of the strategy to buy and hodl, I think this strategy is very simple buy low sell high whether during the ICO or from the exchange. Example many projects are trading below their ICO price right now, so is good time to acquire more from those good projects at this low prices.
