Quick Summary

BlackRock and Fidelity ETFs have changed the game for institutional Bitcoin adoption.

The approval of spot Bitcoin ETFs in early 2024 marked a watershed moment. Now, 18 months later, the inflows tell a clear story.

The Numbers

BlackRock's IBIT has accumulated over $20B in assets. Fidelity's FBTC isn't far behind. Combined, spot Bitcoin ETFs now hold over 5% of Bitcoin's total supply.

What This Means

Institutional money doesn't move like retail money. When BlackRock buys, they hold. This creates structural buying pressure that retail simply can't match.

The Long Game

ETF inflows are creating a new floor for Bitcoin. Corrections are being absorbed faster than any previous cycle.

Quick answer

BlackRock and Fidelity ETFs have changed the game for institutional Bitcoin adoption.
