Cash App vs Sygnum

Cash App (exchange and brokerage) 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 — Cash App at 69/100 (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.

Cash App charges ~1.5% - 2.2% compared to Custom at Sygnum. Over a multi-year holding period, fee differences compound — a point worth considering for long-term accumulators. Cash App's strongest advantage is in ease of use (90 vs. 65), where Cash App's user experience and onboarding flow makes a measurable difference.

The Custody Question

Neither Cash App nor Sygnum has fully eliminated single-point-of-failure risk. Cash App uses Single Custodian and Sygnum uses Regulated Bank. Both models leave your bitcoin exposed to custodial concentration risk — if that one entity fails, your bitcoin could be locked, seized, or lost. For long-term holders, this is the most important factor to weigh.
