Mostly signature campaigns won't accept newbies because there in not enough space in the signature link so you need to rank upto Jr member if you want to participate in bounties.The new merit system is hard for to rank up but there is no merit required for Jr.member so you just need 30 activity to rank upto junior member.
You just explore the bounties sections some may accept newbies as well but the stakes maybe too low for newbie.But you can participate in other bounties like facebook and twitter campaigns.

Try to level up your rank, become Junior Member and you can follow the bounty with Junior Member requirement for their Signature Campaign. There is still a lot Signature Campaign for Junior Member out there although Merit System has been implemented

The best way for you (newbie) is learn more about this forum and most importantly understand the world of crypto. Your post will be calculated later when your rank goes up and apply signature campaign, and now sMerit will make you a little relieved, because with this system your post will be assessed. If your post is qualified then you will go up the rank and can be possible to follow the signature campaign.

Bounty campaigns that accept in their campaign signatures of participants with a rank of the Newbie is very small. You need to write 30 messages on the forum and get the rank of Junior Member.

I have not seen such bounty programs, and why do you need them? You will not make a profit, and if you make a profit, then very little money.

especially for newbie

What is the best signature bounty campaign for newbie ? Yes I think it was the best for beginners but very rare campaign's signature for beginners if we do not careful to find her, be patient to find the campaign signature.

Sir just to sacrifice  searching to find signature campaign accepting a newbie because there was a campaign before if I'm not mistaken they will accept participants even if you are a newbie so you are entitled to their campaign, sorry I don't remember  what's the name of campaign but newbie is also participant but few token will received as reward after the token sale.
