Bitcoin fell 3.01% to US$77,838 on Friday after Fed Chair Kevin Warsh's Jackson Hole speech, with about US$488 million of crypto positions liquidated.

Every major token except solana and BNB is flat or lower over 24 hours, with bitcoin holding a 14% weekly gain and XRP 28%.

One analyst expects Warsh to take a tough line on inflation, but still sees the Fed holding off on rate hikes until at least after the November mid-term elections.

Bitcoin's price is up ahead of Kevin Warsh’s first major speech as chairman of the Federal Reserve.

Bitcoin's price slid before spiking again after the Federal Reserve chair said inflation in the U.S. was "concerning."
