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"
project developers certainly expect the tokens to be launched to be able to be promoted by many people, so that if bounty hunters can be paid in other eth or alt forms, of course this cannot be utilized by the promotion program they carry out, because it aims to increase investors who are interested in investing in it.
