I think that is a big bonus, most of the projects that I have met that give big bonuses like that experience dump when listing in the market. And most good projects do not provide such a large bonus, because even without a large bonus investors will remain interested in the project because of their good products. If they get 40% bonus, they will sell 20% below the ICO price because they still make a profit.
That is also my own perspective, isn't the 40% bonus for the investors are kind of huge? I think it would be better if the percentage was just like or kind of 15%-20% only so that
the price of the coins or tokens will not be fall or dump and maybe it is a good for those investors I guess?
