btcqiwi

I cannot confirm a precise, reliable identity for the Bitcointalk user behind the handle “btcqiwi” based on the provided profile URL. A direct search for that exact username or for a profile at u=18577 did not yield a verifiable, citable result in widely used references available to me at this moment.

The encoded URL you gave corresponds to a Bitcointalk profile page, but without an accessible, stable source showing who that account is or what public statements or registration details it contains, I cannot definitively identify the person or entity behind the handle.

If you’d like, I can continue to search for corroborating information (e.g., posts, signatures, avatar, or cross-referenced mentions) from reputable Bitcointalk archives or third-party profile trackers and cite them. Otherwise, with the current information, a precise identification cannot be responsibly provided.
