If you have a good post quality and descent rank then multiple campaigns will welcome you but there are many campaigns that allows jr member rank to join them so its a blessing for new comers who wants to start earning bitcoins and as they upgrade their ranks they can expect higher income in bitcoins.
Earning from campaigns is not at all a decent package and it is just an additional boost in your savings and nothing else.To say the least there are not much campaign that accepts people now a days and most of the campaign are here for a few weeks and some are really low paying ones and yes the payment are better than using faucet but it is not worth it at the moment.
