what is a good starting point for a newbie account to participate bounty? I already have tweeter and facebook account, can i start it
You can start joining bounty campaigns and make sure that you follow the campaign rules that you are joining. It's easy for you since there are tons of bounties that doesn't require higher rank as requirement for their social media campaigns.
i have fb friends 5000 + 2k followers and 3500 follower on tweeter., maybe that is enough worth to join bounty sosmed ?
That's a lot of friends and followers, basis of rates with social media campaigns are with those (followers & friends). Yes that's enough!
and if for bounty signature i will wait till my level up
Wait until you become Jr. Member.
because i see and read rarely anyone accept signature for newbie
Right.
