As someone who has been in this space for sometime now, I can tell you for free that those who make a kill from airdrops are influencers with lots of referrals. Their referral points also add to the boost. For those of us who just hunt alone, we only get by. My biggest airdrop earning till date that I truly cashed out was Notcoin from Telegram. It was Notcoin that gave fame to the Telegram tap tap as the payout was huge and it drew a lot of attention. I did a bit of trading with that, sold and bought back. Till date I'm still hodling some. Other airdrops I got aren't worth much. Some projects even distributed and then disappeared into thin air without listing in credible exchanges. Some didn't even list at all.
