I heard that bonus in this stage of Pre ICO is 35%, will that stay the same in second stage or the bonus will be lesser?
Well, the bonuses will be lesser for sure. It depends on what do you mean by the second stage
Main crowdsale, of course. Ive thought about it, and the bonus at the start of main sale will be about 15-20 percents.
It is still pretty decent, many ICOs dont have bonuses at all, but it doesnt make them less successful.
