🔏 Does a Bitcoin signature prove who wrote to you?
With a wallet of $BTC , you can sign a message so that someone else can verify that the text was authorized for an address. That message signature does not send funds.
🧩 Fictional example: you receive «I'm Luis» with a valid signature. The signature corresponds to that text, but the name was chosen by whoever wrote the message. It doesn't prove that it's Luis.
🛡️ If you need to verify that the reply is current, ask for the message to include a new code. An old signature can still be valid even if it's forwarded months later.
