It's been a while since I've shared airdrop information, let me recommend some testnets that everyone can participate in, absolutely great opportunities! If you have multiple accounts, make sure to isolate your IP (whether using scripts or manually)

1.monad

2.lens

3.somnia

4.0g

5.reddio

6.tanssi

7.haust

8.botanix

9.moonveli

10.mavryk

I sold the highest on Bear Chain for 12U, although I only had 18 bears per account, I have many accounts!

No-cost airdrop strategies on the testnet are definitely the first choice!
