Four more funds on the on-chain spot ETF flows
What's new
The on-chain spot ETF flow charts now draw four more funds: the Grayscale Bitcoin Mini Trust (BTC), the Morgan Stanley Bitcoin Trust (MSBT), BlackRock BITA and Osprey OBTC. Spot Bitcoin ETF Onchain Flows and Spot Bitcoin ETF Onchain Flows USD show them as their own series, and the on-chain daily total, in bitcoin and in US dollars, now sums them as well.
Each fund starts on its first reliable day, so no early attribution ramp is counted as a flow. The Mini Trust starts on 13 Jun 2025, OBTC on 4 Jun 2025, MSBT on 8 Apr 2026 and BITA on 10 Jun 2026. A fund has no flow on its start day, and its first flow is the next day.
Methodology
The totals restate from those days. History before each start day is unchanged.
The new series are available through the Newhedge API as btc_etf_spot_flows_btc_onchain, msbt_etf_spot_flows_btc_onchain, bita_etf_spot_flows_btc_onchain and obtc_etf_spot_flows_btc_onchain, with matching _usd_onchain series. The on-chain holdings by fund now carry the same four tickers, BTC, MSBT, BITA and OBTC. The data definitions carry methodology version 2026-10-14.
