I know one of my friends joined in its signature bounty campaign, he made about 20 posts for 2 weeks and received about 10k AUTO, he sold it out on Okex and got 2 ETH.
Hi, man, but your friend has a wild imagination. Max price on OKex was near 0.00003899. It can to sell 10k AUTO by 0.3899 ETH. How 2 ETH, I don't know. May be he want but life get him own price? 
I think there are some mistake, Maybe it is 100k, after I check the bounty campaign token spreadsheet, there is no less than 50k, Generally, it is about 100k. So it seems your friend sold it too early.
