What should you watch out for when interacting with testnets?
Some projects have airdropped official tokens to early testnet users, but such rewards have never been promised by the projects.
The same wallet’s private key works on both testnets and mainnets. If a phishing site tricks you into switching to mainnet to sign a transaction, you could lose real assets.
ETH on a testnet is just test currency; it’s not the same as $ETH on mainnet. Currently 2505.49.
Understand how things work before getting started, and don’t place orders based on gut feelings.
