Its called gambling when joining airdrop to get large opportunity with jackpot, must join several kinds of airdrop if want get possibility huge jackpot with one or few airdrop project. Current with testnet project if you are joining around 10 kinds of testnet can't guarantee with all project joining will earn high payment reward but one or two project paid can recovery with ten testnet have joined before.
you can see with Vana airdrop lately how much payment earned by participants and can recovery the reward for several project due payment earn until $1k to $10k.
I agree
There are several airdrops that people can participate in for free, but what you need is time
I see a lot of people saying they don't have the money, but with time and dedication, you can get good airdrops.
A brief summary is to find at least 5 to 8 projects, dedicate yourself to participating in the testnets, be active on Discord, get roles, keep an eye on the developers and be part of the community.
It's not difficult, and you can achieve good results in a few months
