Which country owns Merlin?

Could you clarify who or what Merlin refers to in the context of this question? If we're discussing Merlin as a fictional character, such as the one from Arthurian legend, then it's not accurate to say that any country "owns" him. However, if Merlin is being used as a pseudonym for a specific company, project, or asset in the cryptocurrency or finance space, then the answer to the question would depend on the specific entity or asset being referred to. Could you provide more context or clarify your question so that I can give a more accurate response?
