Casa vs Fidelity Crypto

Casa (dedicated custody) and Fidelity Crypto (exchange and brokerage) serve different corners of the Bitcoin ecosystem, but the question that matters most is the same: who controls the keys? The scores are close — Casa at 83/100 (A-) and Fidelity Crypto at 74/100 (B). When the gap is this narrow, the details matter: custody model, single points of failure, and the fine print on fees.

Where Each Platform Wins

Custody and security — the most heavily weighted category in our methodology at 35% — tilts 16 points toward Casa (86 vs. 70). Casa eliminates single points of failure in its custody architecture, while Fidelity Crypto relies on a model where one compromised entity could put your bitcoin at risk. Casa's strongest advantage is in transparency (84 vs. 65), where Casa's approach to proof-of-reserves and public documentation makes a measurable difference.

The Custody Question

Here's the key difference: Casa has no single point of failure (Self-Custody Multisig), while Fidelity Crypto does (Single Custodian). This matters because a single-point-of-failure model means one compromised entity — whether through a hack, insolvency, or government action — could result in total loss of funds. History has proven this risk is not theoretical. FTX, Celsius, and BlockFi all represented single points of failure for their users.
