Deep Dive

1. BTC Net Inflow

Bitcoin ETFs posted a net $354.8 million inflow on 30 Dec (UTC) after a week of redemptions, signaling renewed institutional demand per the market update.

• This ended a 7?day outflow stretch that had pressured spot prices and sentiment, consistent with year?end de?risking dynamics captured by recent coverage of ETF flows reversing per the report.

2. ETH Net Inflow

Ethereum ETFs also turned positive, adding about $68 million net inflow on 30 Dec (UTC), per the same market update.

• This corroborates a broader shift from holiday?thin outflows toward re?risking into year?end, often linked to liquidity returning and desks reopening, as noted in the report above.

3. Issuer Contributions

The days inflows were concentrated in a few large funds: BlackRocks IBIT ($143.75M), Ark 21Shares ARKB ($109.56M), and Fidelitys FBTC ($78.59M) per the issuer breakdown.

• Concentration in top issuers often amplifies flow impact because these vehicles have deeper liquidity and faster primary market activity, consistent with the notice above.

Conclusion

Yesterdays ETF flows flipped decisively positive for both BTC and ETH, led by big issuers. If inflows continue across multiple sessions, they could provide steady spot demand and improve price resilience. The key is continuity: watch whether top funds keep attracting capital and whether breadth extends beyond the majors.
