I appreciate the responses and I understand the importance of keeping a private key secure and secret. However, I think my question may not have been fully clear.

What I’m asking is this: Is there a way to maintain ownership of a private key even when you intend to reveal it to someone else?

For example, let’s say my private key is 0101010101010101010101010101010101010101010101010101010101010101, and I choose to disclose this key to someone else. Given that I'm willingly revealing the private key, is there a method or technique that would allow me to maintain control or ownership over that key and any future funds associated with it? Or is it simply impossible to preserve ownership?
