Don't really need luck but contribute to their project.
However, there's something that these kind of article didn't disclose. It's the capital needed to follow an airdrop.
The recent airdrop like treehouse, huma, etc requires you to stake your capital and to get good enough money. Usually at minimum you need 10k USD or something to get 1k - 2k reward.
If you're doing testnet however, consider it already botted that you're more likely to get $5 out of it. In some case you can get really good airdrop like walrus, but that kind of thing comes once in a while.
1k return on 10 k investment in few months is not bad at all. You are getting much more to what you will get if the money was kept in bank account.
Difference being that it isn't an investment, but a gamble. You might as well get nothing. And that's nothing compared to Gods Unchained or Uniswap airdrop.
But people weren't waiting for those, they were supporting them and rewarded for it, unlike these bots that want to mine every possible airdrop. I am personally hoping that there's no more of them and these bots will die out. It's like a dead internet theory, but about bots hunting crypto airdrops and bounty hunters spamming other bounty hunters with their share.
