i follow testnet airdrop a lot and it really wastes my time, usually testnet airdrop is used to test a crypto project before switching to mainnet, like using fake money before making it real money, so no one really pays me with real money, at basically tesnet money is just fake money that can't be exchanged for real money, so I no longer participate in the testnet airdrop event because I don't get paid, so think again about joining an airdrop like that
Meanwhile, I see more people making money from testnet than participating in bounty campaigns or junk airdrops. Projects running testnet not all will distribute rewards to their test users. They only distribute to actual testers and give comments so that they can improve their product better than before mainnet, test users regularly interact on their testnet community.
The fact that you do not receive the reward may be that you did not analyze the project before joining, secondly, that you did not make an effort to help them perfect the product, but only participated superficially in the hope of receiving a reward. Testnet is not like the airdrop you are participating in, just spam and you will be rewarded, it requires seriousness and diligence to implement.
I agree to this. I've been on the same situation that I didn't get rewarded from the testnet airdrop but my friend told me that I only contributed a little effort and I did wrong the wrong thing. Usually testnet airdrop needs some money for gas fee and other requirements to be considered as participant. This isn't the usual airdrop where participants do requirements such as spreading the project, promoted or getting referrals. Testnet airdrops also has less abusers since we need money for gas fee. Though not every testnet has a guaranteed reward, So be meticulous on choosing a project if you are aiming for that reward.
