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"
Until now, not many projects have paid bounty hunters using eth or other altcoins. Because those who carry out ICO also need funds for the development of their projects. Of course if payment uses eth, the project is very difficult to do that. Therefore they allocate their tokens to bounty hunters. For the problem of falling prices, of course all decisions are in the hands of coin holders and some project teams must also maintain the price of their coins.
