First you're going to need an active Bitcointalk Account as you already have. Some bounties or airdrops don't allow newbies but there are lots of others that do.
Also, you'll need social media accounts: Twitter, Facebook, Reddit, Medium, Telegram.
Some airdrops and Bounties have stipulations for the amount of followers required on your social media accounts. Others don't.
But Telegram is most important because you have to join that Crypto's community group.
You also need an Ethereum address or Stellar wallet or Waves wallet, maybe other kinds of wallet but those are the two noted mostly so far.
Some bounties and airdrops have KYc requirements too. You might need an official Id document and Utility document. Chall.
You can always find bounties or airdrops to participate in here on Bitcointalk. You could also download ICO alarm from your playstore. You could also search and join "Airdrop king", "Crypto airdrops" and others on Telegram.
