Signature campaigns are the best in my opinion because you can make some good money with that.
Signature campaigns are not for new members (if OP is new) because they need quality posts from their participants and new users wont be able to provide that, and even if someone new manages to do some constructive posts but he wont be able to get a spot right now as mostly campaigns don't accept new members.
for the new members could be paying sigcam for a new coin, they often accept new members and it's been pretty fair
Yeah campaigns are very fair but alot of them are full so it's hard to get in as a new member but once you are higher rank you will see alot more spots open up for you and then its easier to get in and make a quick buck. Also go trading!! I always recommend this to people cause it's quite easy if you get into it.
