I have heard abouty bounty campaigns and i searched and found that you have to be a member of bitcointalk and have a good rank...but i am just a newbie..are there any good bounty campaigns which are accepting newbies in their campaign
Nope. Most of the bouties never accept newbie for signature campaign. Atleast you should be a junior member. Else you can try for social media campaign with your newbie account. But you should have requried followers with you. Better try it. Hope this will help you.
More accurately, some bounty still exist signatures campaign for newbie but very rare and most of those projects do not have much potential because the newbie really does not have the power to persuade and advertise the project. So as you say, we should have a level like junior member if we want to participate in the bounty, it will be more appropriate, even we should aim at a higher level to achieve the highest efficiency for this job
