In most of ICOs, investors can get some bonuses, if they invest sooner. In my opinion these bonuses not only don't cause the ICO to be successful, but also cause the ICO to fail. In some ICOs there is up to 100% bonus.
If I see that there are some people have gotten 100% bonus in pre-ICO, I don't invest in that ICO, Because they will dump their coins after crowdsale and cause the price to fall.
Do you agree with me? What are your opinions?
