As someone who promotes MEMECOINS and other clients' crypto projects using Reddit, FB groups, and Quora, here is what I can gather from my experiences:
If you are consistent and you FARM in VOLUME, just enough of the crypto you farm may produce a positive yield.
Keep in mind that unlocked airdops tend to be self-destructive - at least in terms of price value
Why?
A lot of the people farming 'free crypto' like yourself through airdrops are quick to unload their bags
This depresses the price and pushes the rest of the holders to wait longer or dump at an even cheaper price (close to nothing)
At this point, you really have two STRATEGY CHOICES
1) Just farm whatever you can get your hands on and hope that at least one of the many coins you hold will have a double pump (ie., as an airdrop farmer you almost always miss the first pump). Second pumps are relatively rare BUT they do happen. Be ready to unload when there's a second or later spike.
2) Be CHOOSY about the projects you wish to airdrop farm
Look for the following
Burned liquidity
Widely distributed holding volume
Surrendered contract
Shows signs of being a "real" project - white paper / social media / etc (any indicator that the team behind the coin at least put in some effort)
Social media presence - X / Twitter is a must but the bigger and more widespread the presence, the better.
Good luck farming airdrops!
