🧩 $BTC Smashes Through $77K: Is Institutional ETF Demand Driving a Macro Breakout? Bitcoin has staged an explosive vertical rally, breaking out of a multi-week consolidation zone around $63K–$65K to print new highs near $77,418. The price broke decisively above the upper Bollinger Band, riding a steep impulse wave that expanded volatility across the 4-hour timeframe on WhiteBIT chart. This rapid momentum push pushed the 4-hour RSI to extreme reading levels near 94, reflecting intense spot buying pressure and aggressive short squeezes. Meanwhile, the 20-period Moving Average sits down near $68.9K, marking the primary technical baseline after a near-vertical breakout. The fundamental driver powering this move is massive institutional capital inflow through US spot ETFs. US spot Bitcoin ETFs recorded $608.3M in net inflows on Thursday alone, pushing weekly totals past $1.6B and August inflows to a year-to-date record of $2.07B. Spot Ether ETFs joined the rally in parallel, drawing $220.8M in daily inflows - their largest single-day intake since October 2025 - raising total net assets to $13.58B.
