Actually not all airdrops now are requiring some gas fees or making up some transactions to be eligible when it comes to airdrops. You could be able to choose up
on the following methods.

1. TG drops (time consuming and possible have some ton gas)
2. Node (Free) Need to install web browser extensions
3. Play to Earn/Airdrop
4. Minting NFT's with having that small gas fee

If you are really that making up some full time on dealing up with airdrops then it would really be that up to you whether you do deal up most with those
transaction based or liquidity accumulation for getting points on the moment that you do deal up with these things. The only thing that you should be having into your mind is that not all airdrops would really be giving out that guarantees that you could be eligible in the end of the project TGE or into those moments that the value of the said token or project is really just that not justifiable.

Always put up into your mind that this isnt something that could make sure profits or something that could someone make a living. Be better that you do make out some side
hustle aside from your day job which is into these airdrops. Also, there's no assurance when it comes to profits or free money on the time or moment that you do deal up with these things.
It will really be that up to you on how to deal with it.
