For me I pick bitcointalk signature campaign. It is easy and simple and it doesn't require much time to do as well. I also feel like I am not working at all. I can also help other people with my post and other opinions while I am working on the other hand. Also most often the signature campaigns has the biggest allocations in bounties which is good.
Yes that's right, the signature campaign is a Bounty campaign that is big enough to make a profit, if we have the highest level in this Forum like Hero / Legendary it will be very possible to reap profits from the Bounty campaign. Besides the signature campaign, I also wrote Blogs and articles, because I thought this was a rather large campaign in the distribution of the rewards.
