I dont understand the reason to conduct VIP ICOs. Anyway, the number of participants is less than in case of main stage.
If you didnt know, therere various categories of users. Some of them is ready to purchase tokens only if theres a significant discount.
But it isnt profitable for platform cause they receive more tokens for less money.
First, the number of tokens that are put on sale in such ICO is strictly restricted, secondly, nevertheless, this expands the target audience and increases the amount of fees collected.
Okay, but why not make the conditions of participation profitable during all the ICO? Lets say, everyone could receive additional 5% regardless the amount of investment.
