I never had a payout since July 2018. There are a lot of scam ICO's and I just happened to join their bounty, how unlucky. I even worked for 3 months and received nothing on bounties. I've been thinking on different ways to earn but signature is the most painful if it ended up being a scam because it takes a lot of months before it finished and takes months before distribution. 2018 is not really good for bounties. Maybe things will be better next year.
