Bitfarms is trading 4.1% down at $3.38, with rising Treasury yields a possible contributor; no clear company-specific catalyst has emerged. - Bitcoin was up 0.96% since the previous close and Ethereum 0.63%, so crypto prices do not explain the decline. - Reuters reported the 10-year Treasury yield reached 5.306%, its highest since mid-2007, as energy-driven inflation concerns weighed on bonds; modest index declines leave the cause uncertain. - No October 1 company announcement appeared in available press-release listings; the latest releases predate the session.
