I see this topic is quite recent. Social media campaigns? I dunno about that. I participated in translation bounties for one of the best ICO (Farmatrust) and the bounty for me was not what i expected. Oh well... We are in a bear market i guess.
I am currently participating in signature, and i wait for payout on several bounties, including Nauticus, Flogmall, and w12 campaign. First two got the required crowdsale funds, but i fear the worst right now with this market.
