Let's talk about testnet activity.
Some projects have airdropped official tokens to early testnet users, but these rewards have never been guaranteed by the projects.
One thing many people overlook: testnet activity records can help projects identify active users, but ultimately, whether tokens are issued and how they are distributed are up to the project.
Don't treat testnet points as guaranteed returns. Be realistic about how much time and transaction fees you're willing to spend.
ETH on a testnet is only test currency; it's not the same as the $ETH on mainnet. The current price is 1816.3.
