Some tend to believe that they can trick others (maybe authorities?) with claims they had Bitcoins in the past but they don't have anymore. I have some hunches, but nothing clear (and I don't want to give better ideas to others too). However, very shady things.

(Also there are the forks, you know..)

Quoting for reference.

Please help me to understand what is the use of this addresses. Is someone thinking to have a museum of high held BTC addresses. I mean serious what kind of business you are thinking with it?

By the way, remember the private key will be known to two person. You lost and the one who will sell.
