How to distinguish air coins, popular science! The crypto circle is deep water, don’t touch if you don’t understand, refuse air coins!
Strip those air coins packaged as "public chains" clean. Just remember the following three key points to avoid most pitfalls.
First point: Look at the "property certificate" — is it the "landlord" or the "tenant"?
True public chains, like Bitcoin, Ethereum, Solana, all have their own mainnet. You can think of it as an independent company with its own office building (mainnet) and financial system (browser).
How to check the "property certificate"? You need to find something called a "block explorer". A true public chain must have its own dedicated explorer; just input any wallet address, and you can see all transaction records, public and transparent, no one can deny it.
