I stop following airdrop so i can't help you in that aspect, but as for bounty it is pretty simple as long as you are in this forum all you need is visit the altcoins bounty section and make your selection there, you can also find few airdrops along side the many list of bounty we there, good thing is we have several bounties in that section so enough choices to be made, imo, this forum is where you can get the best bounty and as for airdrop there are only few.
