we all know that some bounties do require higher rank right now, for Jr. members like me i think airdrop is the new opportunity to get extra profit. 
There are still a lot of bounties available for JR. members, even on social media you can join.
airdrop is a way of earning free money it is an opportunity for all to do all at the same time to keep you busy and your time worth.
As Theymos remove signatures for jr. members some of the bounties are still accepting jr. member and you can still hit a jackpot if you will just keep looking for a great bounty.
I really appreciate high ranks helping us out. I'm really worried that i wouldn't be able to join any bounty since i am just a beginner, having said that there are still signature campaigns available for us really kept my hopes up. I also don't want to chase merits.
