Bitcoin Defies Macro Headwinds with $81K Breakout: Is Institutional Demand Sustainable?

Bitcoin (BTC) surged 6% to $81,278.78 on September 19, 2026, driven by institutional inflows into US spot Bitcoin ETFs, a temporary SEC exemption, and a short squeeze. BlackRock's IBIT ETF saw $183.7M in inflows. The SEC's exemption allowed on-chain trading of tokenized stocks, boosting altcoins like UNI and ARB. Short liquidations added $243.54M to the upward momentum. Bitcoin's technical indicators suggest strong momentum. Weekly net ETF flows remain negative, cautioning against overoptimism.
