im not sure i understand correctly the ladder graph of bonuses. if you participate in round 1 it says maximum 9% bonus. does that mean if you ONLY particpiate in round 1 you only get 1% and dont get the 1% on every other round you dont participate in?
The size of the bonus for each round is dependent on how many rounds following it sell out. So what you see is the maximum bonus in round one is 9%. That is the bonus if the ICO sells out.
For another example lets say the ICO only sells out through round 5. That would mean that round one participants would receive a 4% bonus, round two participants would receive a 3% bonus and so on.
Bascially it is 1% bonus for every round selling out after the round you buy.
