What TCB Research computes from this

  • Over the last five sessions, net ETF flows totalled -$142M (2 of 5 days positive), a net distribution trend (TCB calculation).
  • Since launch, US spot Bitcoin ETFs have taken in a net $53.4B, about 840,502 BTC at today’s price, a structural buyer that did not exist before 2024 (TCB calculation from Farside cumulative data).

Methodology. Net flow is the daily total across all US spot Bitcoin ETFs. TCB converts the dollar figure to coins at the current Bitcoin price, then divides by daily issuance of about 450 BTC (3.125 BTC per block across roughly 144 blocks a day after the 2024 halving) to express each flow in days of mined supply. Cumulative figures are net since the funds began trading in January 2024.
