U.S. spot Bitcoin exchange-traded funds attracted $180.4 million in net inflows on March 13, extending a positive streak after earlier March volatility. Data from Farside Investors shows BlackRock's IBIT accounted for the bulk, adding $143.6 million. Fidelity's FBTC followed with $23.2 million, while Bitwise BITB, ARK Invest ARKB and VanEck HODL contributed $3.1 million, $2.4 million and $8.1 million respectively. Grayscale GBTC, Invesco BTCO and Franklin Templeton EZBC recorded zero daily flows.
The rebound comes right after a $348.9 million outflow day on March 6. Subsequent sessions saw $167.1 million on March 9, $246.9 million on March 10 and $53.8 million on March 12. Since launch, BlackRock's IBIT has accumulated over $63 billion, while Fidelity's FBTC holds nearly $11 billion — showing heavy concentration in top products.
BlackRock IBIT leads with $143.6M inflow
Farside data confirms IBIT captured nearly 80% of daily inflows. The remaining $36.8 million distributed among FBTC, BITB, ARKB and HODL. Zero inflows for several funds suggest capital continues to favor the largest issuers. After early March outflows, the flows have turned positive for four consecutive trading days, signaling renewed institutional appetite.
Analysts flag low-resistance zone up to $82,045
Crypto analyst Ali Martinez stated Bitcoin has entered a “low-resistance zone,” with minimal selling pressure until $82,045. He added that key support sits at $66,898. Analyst Michaël van de Poppe shared a 4-hour chart showing BTC forming higher lows near $65,117 and currently trading around $71,720. The chart indicates a resistance band between $76,604 and $79,127, with a further upside target near $80,646. Poppe described the session as “classic Friday afternoon price action” — a run to recent highs, liquidity grab, then reversal. He expects BTC to retest highs within the next two weeks.
