Bitcoin Flashes Bull Market Signals as Spot ETFs Pull $1.07 Billion in Inflows

Bitcoin is flashing classic bull market signals underpinned by rising realized capitalization and sustained institutional accumulation, according to CryptoQuant founder Ki Young Ju. The asset retreated to around $81,000 on Oct. 22 after reaching an intraday peak of $84,739 on Oct. 21. U.S. spot Bitcoin ETFs accumulated roughly $1.07 billion in net inflows over three sessions ending Oct. 21, including $524.8 million in single-day inflows led by BlackRock's IBIT and Fidelity's FBTC. Ju highlighted that fresh capital inflows and paused long-term holder selling show Bitcoin remains in an early bull market phase.
