You can technically start with $50–100, enough to cover gas fees and some small interactions. Most quality airdrop opportunities require on-chain activity rather than large capital commitments.
That said, some protocols reward larger liquidity provision more heavily. If you provide $10,000 of liquidity vs. $100, the allocation will often reflect that. But for most beginner-level farming — swapping, bridging, using DApps — a few hundred dollars plus enough ETH/SOL for gas gets you started.
The honest answer is: don’t put in money you can’t afford to lose. Gas fees can add up across multiple chains. Some projects that seemed airdrop-certain end up never launching a token, or filter out most farmers. Budget for the worst case.
