BNY Mellon vs Sygnum: What the Data Shows
BNY Mellon (stablecoin-custody) and Sygnum (dedicated custody) serve different corners of the Bitcoin ecosystem, but the question that matters most is the same: who controls the keys? The scores are close — BNY Mellon at 76/100 (B) and Sygnum at 67/100 (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
On custody and security, these two are within 3 points of each other (88 vs. 85). When custody scores are this close, look at the specifics: key management model, insurance coverage, and whether either platform has a single point of failure. BNY Mellon's strongest advantage is in transparency (85 vs. 70), where BNY Mellon's approach to proof-of-reserves and public documentation makes a measurable difference.
The Custody Question

For long-term holders, this is the most important factor to weigh.
