Old BTC addresses private keys - Why some people ask about them?

[Leooo]

Why there is some demand of old BTC addresses private keys? What they use them for? Anyone have any idea?

I'm not sure and I don't think there's anything that could be gain from the private keys of an old bitcoin address.. maybe they're trying to take advantage of the unclaimed fork coins??  anyway, could you paste a link proving that there's a demand for this, I'd like to see the thread.

Each of the threads that you linked (on your 2nd post), has the answer to your question (for the most part, it's what " Potato Chips" mentioned earlier):

We check for Bitcoin Cash, Bitcoin Gold and CLAM all at once!

Why am I buying this? Shitcoin airdrops.

With the exception of this one:

I have to pay taxes anyway, due to recent trading.

The main issue is that I moved all my coins to Trezor a while back and dumped all my old private keys. As I want to be safe I want to be able to show a proof that I hold the coins for quite a while to prevent any issues.
