I was once an investor had few gains to some ICO/crowdsale but made many losses so I decided to stop participating in ICO instead I do bounties and buy it thru exchanges from bounty hunters dumping it.
I know for a fact that most of you know this situation and are guilty of it, price tends to tank due to bounty hunters selling their share of tokens for cheap. I think its better to pay hunters in eth or other alts rather than risking the price of their token or coin in that way they could also help their investors and boost confidence to their future and their project. Well for me a falling price is a mark of a failing project "ICO's"
You chose the right strategy. But you shouldn't blame on all the problems the hunters. Usually the reward for their work is 2-3%. After listing, the price of a token dumps about 10 times. Its not profitable for hunters to sell a coin for a low cost because its result for their work for many months . For many hunters, this is an opportunity to get coins without attachments.
