what is the ending date of the campaign?
As they said at telegram, maybe after 2 months, when ICO ended.
How much p is the time required to conclude bounty rewards?
I dont understand your question. But i think we can get stake on any day of their bounty. So distribution depend on this.
When will we get paid, Weekly, Monthly or epat the end of ICO?
End of ICO of course.
Why tokens are frozen for a year..?
I think to avoid dumping problem of who have GIL from bounty.
