Well you have researched it,and still you are asking for a signature campaign for newbies? i dont think you really dig researching because if you did you wont bee asking ask because you will know that you need atleast jr.member rank to participate any of these signatures,but dont worry there still a good way to get stakes from these new campaigns by doing social medica bounties,facebook and twitter will only require you some friends and followers the you will do whatever the bounty says then you will get your stakes at the end of ICO.
