Yes i have already done my research but i am still very confused thats why i want your help guys...please give your opinion
Well, honestly I can't provide a good answer to this question, but this is my principle when choosing a signature campaign.
1) Try to look the bounty which has a high allocation to a signature campaign. I can say 30-40% is enough. Usually, Sylon (Bounty manager) has a high allocation for sig camp.
2) Earning also depends on the project, so choosing a Bounty same as choosing an ICO to invest. DYOR is the best answer. A basic rule like check the team background, whitepaper, products (MVP) is also a must for us as a bounty participant.
