What is it like to lose Bitcoin?

This is still my friend's story.

He lives in a first-tier city.

That year, Bitcoin was 100 yuan each, and under the repeated persuasion of an old Bitcoin miner XX (a well-known figure in the crypto world), he bought 100 Bitcoins.

Eight years later, Bitcoin had reached a very high price. He remembered these 100 coins and started looking for the note with the address and password.

Because he forgot which book the note was tucked into

and which of the dozens of houses he owned in this city had the bookshelf with that book.
