Thanks. But though I may conceptually be "signing full ownership to a new recipient wallet", from a chain analysis perspective, there may be no way to know that that new wallet is associated with someone else. It could just as easily be another wallet I created. (Of course if the new wallet has KYC Bitcoin associated with the new owner, that would presumably associate the Bitcoin transferred from me with their KYC. Right?)
From a chain analysis perspective, yes. You are the last (only) known owner of those coins. But the investigation carried out by the police or other law enforcement agencies is not limited to chain analysis. In the case of some kind of crime related to "your" coins, you will probably be invited to an interview where you will simply provide evidence that the coins have changed hands and that you no longer have anything to do with them. On the other hand, with the information you provide, you may even help police detectives identify the real criminal.
