Bitcoin ETFs notched a robust total net flow of $663.9 million on April 17, with BlackRock's IBIT pulling in $284 million, Fidelity's FBTC at $163.4 million, and ARK's ARKB securing $117.9 million. Bitwise's BITB added $38.2 million, while smaller players like BTC and MSBT contributed $29.1 million and $16.6 million respectively. Grayscale's GBTC flipped positive with $4.2 million, a shift from recent outflows, underscoring renewed institutional appetite in the wake of last quarter's crypto market trends and Bitcoin halving hype. This surge aligns with broader BTC momentum, potentially fueling further upside in a landscape where ETF flows often precede major rallies.

From a technical confluence standpoint, Bitcoin trades at $77,018.5 on the 4-hour chart, firmly above its EMA50 at $73,896.39 and EMA200 at $71,068.92, confirming the bullish trend structure that institutional desks are leaning into for BTC price prediction plays. MACD shows a golden cross with a bullish reading of 1012.42, signaling sustained momentum, while RSI at 66.18 sits neutral but edging toward overbought territory—watch for any exhaustion here. Price hugs the upper Bollinger Band resistance near $77,798.77, with support down at $72,887.52; confluence points to a potential test of that upper barrier before a tactical pullback to the EMA50, where buyers could reload for the next leg up amid ongoing crypto market hype around assets like TAO and Bitcoin's dominance.
