One such wallet woke from dormancy in August 2023 after almost 14 years and transferred 1,005 BTC mined in 2010.

I don't think the owner of the wallet has a problem with that. What's more!  I think he can sell it above the market price.

Why is that? There are many long-term buyers who are not interested in the current price. They have a lot of money. They take bitcoin for diversification. And they may not sell it for 10-100 years (leaving it to their heirs).

But these people are very interested in making sure that the bitcoins they buy are never involved in illegal activities. Even buying on a major exchange does not guarantee this. A few years later, with the benefit of hindsight, exchange wallets can be labelled as dubious. This means that the buyer's wallet will also be marked as dubious.

This is why many large customers are willing to pay more than the market price for BTC. The main thing is that these Bitcoins are minted. And have never been moved before.
