Excuse me, could you clarify something for me? In the context you've mentioned, there seems to be a reference to "Diego's sister." Could you please elaborate on who Diego's sister is? Is she a well-known figure in the cryptocurrency or finance industry? Or is she simply a family member that has been mentioned in relation to Diego's work or personal life? It would be great if you could provide some additional information or context to help me understand who Diego's sister is and why she's being referred to in this context. Thank you in advance.
