Casa (dedicated custody) and Strike (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 Strike 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.

Casa eliminates single points of failure in its custody architecture, while Strike relies on a model where one compromised entity could put your bitcoin at risk. On fees, Strike wins by 10 points. Strike charges ~0.3% spread compared to $30 - $250/yr at Casa. Over a multi-year holding period, fee differences compound — a point worth considering for long-term accumulators.

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.
