shouldn't you be able to trace the transaction through the stamps and find out? that's the entire point of bitcoin: to trace to proof of work. otherwise: it's worthless stake. seems odd you wouldn't know. i'm not trying to "get at" anything. you posted a brag about the usefulness of bitcoin as a financial tool, and since you are a taking a leadership role, it's your job to explain how you achieved it so others could follow. i was asking questions to clarify how what you stated was possible.
