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"
Your speech needs a review
Bounty rate does not exceed 3% of sold tokens in the best projects
So it is difficult to affect this ratio to the rest of the sold
The lower prices of most ICOs refer to lower liquidity in the market
Note that BTC alone dominates 52% of the market.
