Bitcoin fell to 78 400 and failed to decisively clear above 80 000 dollars, according to Cointelegraph. Market participants were evaluating Fed Chair Kevin Warsh's remarks at the Jackson Hole symposium.

In the source's paraphrase, Warsh maintained a cautious view on US inflation dynamics and did not grant decisive weight to recent softer readings. This helped fence Bitcoin in and set a restrained backdrop.

The significance of the event remains limited: only Cointelegraph's meta-summary is available, not the full speech or independent corroboration. The main attention should be on Bitcoin's subsequent reaction to Fed statements and US inflation data.
