I am going to see how this will eventually go. I just discovered I have an account with them after attempting to register, I was notified I already existed on their database. I still can't figure out the terms of engagement and how to vote or if this is over.
According to their site
https://support.okcoin.com/hc/en-us/articles/360032912692-Let-s-Build-Bitcoin-Together-A-1-000-BTC-Donation this one will end up tomorrow.
How long will the campaign run for?
Voting will start on September 3, 2019, at 6:00 am PT and end of September 27, 2019, at 9:00 pm PT.
All of the informations are on that link.Have a time to read it up and you might still able to catch up for the last day.
