Bitcoin ETFs posted a robust total net flow of $238.4 million on April 20, with BlackRock's IBIT dominating at $256 million while Grayscale's GBTC saw outflows of $24.9 million, signaling sustained institutional interest in BTC despite mixed performances from funds like FBTC at -$6.6 million and minor inflows in BRRR and MSBT.

From a technical confluence standpoint, BTC trades at $75,645.75 in a bullish structure, holding above the EMA50 at $74,693.93 and EMA200 at $71,969 as key supports that have capped downside over the past six months. Momentum sits neutral with RSI(14) at 52.52, but the MACD(12,26) death cross at 159.18 hints at bearish pressure building; price hugs the middle of Bollinger Bands, testing upper resistance at $77,091.39 where volatility could exhaust, setting up a potential dip to lower support at $74,129.22 before resuming the uptrend—watch for confluence here as ETF flows bolster macro buying in this Bitcoin ETF flows environment, tying into broader crypto market trends and BTC price prediction models.
