I heard about Zeex from friend and I liked it instantly.So many retailers already on the list and project is not started properly

When is the sale?
Your friends have informed you well

the sale will begin soon.
The public sale will launch before the Q3 ends so most probably it will be on September like what mostly of the icos now. I know you guys are excited about it so just keep your eyes here for announcement.
Finally, we have a concrete answer regarding the beginning of the sale

That's great news - finally when have a ballpark on the start of the sale - how long will it last?
At least month or until the HC is reached.
are there some prediction and maybe some info on how private sales are proceeding?
How much I know, except 24 hour sales results they haven't posted anything, but I believe sales are going well
Yes, they probably wouldn't disclose actual numbers, but maybe some prediction so we can know based on this how much of all tokens will end up in public sale.
