Most of the "decent" airdrops require you to do X thing in order to be eligible for their airdrops and nowadays you need to spend some to actually interact with their platforms. Some of the free one is already dead and most of them are just a scam for free promotion so it's just not really a wise thing to do anymore.
That is because any free-to-do tasks are doable by everyone and gets saturated really fast, and then there are airdrop farmers who further dilute the reward pool with multi-accounting, taking more than their fair share.
I'm not saying there are no farmers involved where there are real dollar interactions counted, it's just that requiring real money excludes free farmers, and obviously there are more free farmers than paid because free farmers have only to make effort, and if you have lots of free time there is nothing to lose from your side.
So it's good idea from project's perspective to reward only users who used real money, it doesn't solve farmer's problem completely but solves to some extent.
May be now Airdrop definition is changes, whatever i think now there are no Airdrop will be free, of course you have to spend some money as like 10$-20$ in their platform as like some transaction in their mainnet it's required mostly new platform then you can be eligible that's is okay but it’s unacceptable to stake big amount and personally i am ignoring such projects Airdrops.
Well there are really some for free.
What is $10 to $20 dollar fee for transaction in exchange for a bigger reward? I think you are aiming for literally full airdrop but spending on gas fee for claiming or what is such responsibility of the users. You already given a free tokens called airdrop you wont expect the project to give it all even the process or cost to received it.
I think 'potentially' word should be there in bolded statement, i.e $10 to $20 fee for exchange for a potentially a bigger reward.
Requirements to be eligible for airdrop are getting complex, projects will rarely reward you for mere couple interactions or for interactions with low amounts, retrodrop's are all luck, you spend for interactions on 10 projects then may be one of them will reward you. If you don't have extra money lying around, it's better to stick with free projects, and try to get starting funds from there.
Or to stick with projects having probability of retrodrop, but your funds stay safe, for example, staking protocols. $JITO is prime example of this and other is EigenLayer but to stake there gas fees were expensive since it's on Ethereum. Though, Eigenlayer stakers gonna recoup easily, because other projects are accounting Eigenlayer stakers for their airdrop's criteria.
I also see that the Cosmos network is now widely rumored to be getting an airdrop because of the many new projects joining and becoming a trend such as INJ and ATOM.
Hopefully there will be an airdrop for this chain.
There have been plenty already on Cosmos.
