I want to know if people from the early days of Bitcoin who mined are still here. If you want, you can post here a signature for the text "bitcointalk" with your oldest key so we can check who has/had the oldest mined Bitcoin. Even when the coins were sent, you can post the signature for that address.
Yeah, for what reasons?
Maybe they are testing a new 'NFT' within the Bitcoin blockchain where old (empty) Bitcoin addresses are the 'NFTs'.
Someone may want to convert old BTC addresses into NFT and sell them for large amounts later, this idea may achieve great profits after 10 years have passed, as these old addresses become of archaeological value as they are old Bitcoin addresses.
In this case, it does not matter whether you own the private key or not, because this address will not be used to send or receive bitcoins, but only as an NFT.
