Bounty campaign is not worth it, only wasting your time with worthless coins, avoid it.
I tried bounty campaign before and I ended up nothing, it is not easy to earn money there. You need a lot of patience and hardwork while you are uncertain about the coins that you can earn. Bounties are ridiculous because it feels like you are working for nothing but a small amount.
Keep in mind, signature campaign is only a bonus from your dedication to forum... similar like people give merit (bonus) on a high quality post.
Based on my observation in this forum, there are a lot of people who are making signature campaigns as a source of profit but they are not really making quality posts. Never forget to make an informative posts that will help other people learn and posts that can create critical discussion towards a certain topic because that will make the thread more educational towards other people when it comes to cryptocurrency.
