This question you asked a year ago and today is still a newbie, I think you're not serious about learning bounties
You even answered to 1 year old question.
Do you think that's still valid?
signature campaign is great bounty. its is more profitable than other bounty campaign. you need just some logic and experience about Bitcoin. it is not hard. you can can it.
fyi you can earn around 5-10x times bigger if you joined on translation bounty rather than signature bounty
