When will the bounty campaign end?
You can check it in the VisionBanker Bounty thread but to answer your question, it will end once the ICO ends.
I visited the OP, but can not find bounty link here, but after searching, I found this one:
https://bitcointalk.org/index.php?topic=5164375.0In short:
Bounty campaign will start on July 13, 2019
Bounty campaign will end when ICO ends.
But it seems that we have not known end day of the ICO, right?
