Who owns the Bitaxe?

A single reseller registered the names Bitaxe, Nerdaxe, NerdQaxe++ and Nerdminer as trademarks, two of them for devices it does not even sell. In April 2026 it used them to have 71 of our pages removed from Google. We show the register entries, the letter from their lawyers and the contradictions that come with them.
