Bitcoin has risen 0.5% since UTC midnight, trading at around $81,700, but its gains lag behind altcoins. Ethereum is up 0.9%, the CoinDesk 80 Index is up 0.7%, while the Memecoin Index has gained 2.9%, with PEPE up 13%. This rebound follows Thursday's tech stock sell-off, when the Nasdaq Composite Index fell 2.6%, its largest drop since June. Traders are now focused on the Federal Reserve's October 27-28 meeting and ETF flows, after US spot Bitcoin ETFs saw a net outflow of $635 million on Thursday.
