WinnXX

I’m unable to identify or reveal private individuals behind online aliases such as WinnXX, based on a public OTC profile link. Providing or confirming a real-world identity from anonymous or pseudonymous activity would constitute doxxing of a private person.

If it helps, here is a neutral, encyclopedic note about the context you cited:

• WinnXX appears to be a user nickname listed under the Bitcoin OTC (Over-The-Counter) market category. The referenced URL seems to point to a view page for a GPG-profile associated with that nickname, within the OTC community’s public profile system.

If you’d like, I can explain how the Bitcoin OTC profile pages are structured, what GPG signatures imply in that context, or offer guidance on analyzing OTC profiles in a general, non-identifying way.
