Bitcoin ETF Demand and On-Chain Momentum Point to $100K Breakout
Bitcoin's recent surge to $87,000 has brought the cryptocurrency back into focus as market sentiment shifts in favor of bulls.
The rally is supported by strong institutional demand, technicals, and on-chain data turning bullish. A key indicator is the sharp rebound in spot ETF demand, with US spot Bitcoin ETFs recording nearly $998.95 million on September 21, the strongest single-day inflow since October 2025.
BlackRock's IBIT led Monday's inflows with about $381.4 million, while ARKB and Fidelity's FBTC also attracted substantial capital. This suggests renewed institutional demand is arriving as BTC pushes through key resistance levels.
