You can start with $50 to $100. That covers gas for a handful of transactions on a cheap chain and enough activity to register on most testnets and quest campaigns.
Whether you should is a different question. The answer depends on which of the three farming routes you pick. They have very different costs.
The three routes and what each costs
Testnets cost time, not money. Test tokens come from a faucet and are worthless by design. You pay in hours: bridging, swapping, deploying, checking in. For someone with more time than capital this is the only route that makes sense. It is the one we point beginners at.
Activity farming costs low hundreds. Swapping, bridging and using live protocols on a real chain. A few hundred dollars plus gas on a cheap network covers it. Gas is the variable that surprises people: the same sequence of actions can cost a few dollars on one chain and considerably more on Ethereum mainnet.
Capital farming costs whatever you can lock up. Some protocols weight allocations by how much liquidity you provided and for how long. $10,000 of liquidity is treated differently from $100. There is no clever way around that. This route is for people already deploying capital on chain who are adding an airdrop angle to it.
The costs nobody counts
Gas is the obvious cost and rarely the largest one.
Opportunity cost. Capital parked in a protocol for eight months to earn points is capital not earning anything else. If the same money would have made yield elsewhere, that yield is the bar the airdrop has to clear before you are ahead.
Bridge and swap spread. Every move between chains takes a cut. Farming across five chains means paying that spread repeatedly. The total is easy to underestimate because each individual cut looks small.
Time. Daily check-ins and weekly tasks across several campaigns add up to real hours. At any honest hourly rate, that is usually the biggest line in the budget and the one nobody puts in the spreadsheet.
What comes back
Most airdrops pay somewhere between a few dollars and a few hundred. The drops people talk about are outliers from a period when fewer people were farming. They are the reason expectations are calibrated wrong.
The payout shrinks further after the work is done. Sybil filters remove wallets from published eligibility lists: Linea cut 516,960 of 1,297,203 addresses before paying. And some announced drops never arrive at all.
A sensible budget
If you are starting from zero, use testnets and quest campaigns until you have seen a campaign run end to end. They cost time and teach you what the rest of it involves.
If you are putting money in, the rule is the same one that applies to everything else in crypto: the amount you can write off completely without it changing anything. Not the amount you think you will get back, because there is no promise attached to any of it.
If you are already active on chain, you are in the best position of the three. Keep using what you use, on one wallet, then treat allocations as upside on activity you were doing regardless.
