There are some Signature campaigns available in Altcoin bounties section that accept Newbie as well. But I still suggest you to become Jr. member and then apply for any campaign. Till then you should understand this forum better and keep on doing some quality posts.

Now lets come to earning equal to a Jr. member. Let me tell you if you joined a signature campaign of an ICO and it raised good amount. You can even earn equal to a hero member as they pay you in stakes and thus, you get some percentage of what they raised. Many such campaigns came and are coming which seems to have potential and joining such can definitely earn you good through signature campaigns.
