Re: Why has my newly created Bitcoin address already been used?
Am I the only one who generates my paper wallets manually?
Flip a coin 11 times, turn the resulting number in to a BIP39 word from the word list. Repeat 22 more times.
Flip a coin 3 times, calculate the checksum using a permanently airgapped computer, pick the last word.
Write down on paper, import in to a wallet or iancoleman on your permanently airgapped computer to generate a receiving address (Optional: add in a passphrase and write that down on a separate piece of paper).
Whole thing can be done in 15-20 minutes.

If you are calculating the checksum on an airgapped computer and generating the address on it, why not simply create the seed/private key on it as well ?
That would be my approach.
I'd rather spend 2 minutes typing commands than 15 minutes flipping coins
