Let's talk about digital signatures.
Digital signatures don't encrypt transaction details; the amounts and addresses of on-chain transfers remain public to everyone.
To be honest, I hadn't noticed this before either: anyone asking you to provide your private key or recovery phrase to “verify a signature” is a scammer. A genuine signature never requires you to hand over your private key.
When transferring $BTC , the wallet signs the transaction with your private key, and nodes across the network verify the signature using the public key. Current price: 83872.01.
Don't bet all your savings on a single prediction.
