As a junior member, you can join some signature campaigns. But the payout is quite low, it is like $0.03 per post. So it is better to join when the rank is higher.
I think it does not matter when you jr.member immediately joined the signature campaign despite a payout very low, so when you build your account until you reach the highest rank you can still get paid
Right. I also got suggestions that i shouldn't join a campaign when i don't have a higher rank like full member or more, but i thought something is better than nothing, so why not join a campaign and earn some bits until you reach a higher rank.
Use the time to learn about the forum, and bitcoin in general. Once you put a signature up you are throwing up a crosshair for ban if your posts are crap or one liners. If your learning still and don't have signature more likely you will not be banned.
So I suggest all full member at lowest joining. The ones under it really are just dust your getting anyways. I think your jumping the gun as you already did join one it appears.
