Tell me please such a question. What do you plan to do with unsold tokens after the ICO?
We will make genesis block only with amount of sold coins + bounty and referral.
For example:
Total 10 bln
Sold 1bln
Bounty+Ref 200 mln
In this case we will make genesis block with 1,2bln, other 8,8bln will wait for mining.
