There is a pre-sale lottery. If you win the slot, you will able to participate the pre-sale with 40% bonus. But it requires the purchase amount of $10k.
If you join the crowdsale in the first hour, you will have 30% bonus. That's quite enough for me.
It seems a new ico method that already brought the pre-sale participant to take a chance in betting how many bonus they can get. But if the pre-sale maximum bonus already offered 40% and that was a little gap with the ico bonus up to 30%
It seems not a problem at all.
