At the moment, testnet on airdrops is a bit of a trend that is still happening now; the grass is still there, berachain, and there is something new now that I saw and read about in our local area, then accompanied by meme coins that were also recently really making noise in the market.
I agree with you. If looking for how to make money from crypto I think airdrop and testnet are still the best options. I have seen several times that airdrop or testnet projects can provide significant profits such as Celestia and Manta. Notcoin is also the latest project that can provide good prizes. My friend was able to earn around $200 to $500 from Notcoin some time ago.
