Who each is for

Fit follows the custody model, not the brand.

Onramp

Multi-institution custody

Separate institutions each hold a key under their own ceremony; no one of them can move funds.

A good fit for
  • Holders who want independence to be structural rather than a personal discipline — the separation survives your attention span, your health, and your heirs
  • The person planning for a non-technical survivor: the heir works with institutions and documents, not devices and dice
  • Advisors, trusts, and family offices that need no-single-point-of-failure custody they can explain to a fiduciary
The wrong choice for
  • Holders whose definition of bitcoin includes holding a key personally — you do not hold one, and no amount of structure changes that
  • Small balances: institutional fee floors make no sense under six figures
  • Privacy maximalists: multiple regulated institutions know the position
  • Anyone who wants to be able to move coins alone at 2am — the design goal is precisely that nobody can
Sygnum

Qualified custodian

A regulated institution holds keys in segregated accounts under a legal framework built for it.

A good fit for
  • Entities that must satisfy a regulator, an auditor, or an investment-committee mandate
  • Holders who want institutional process — SOC audits, segregation, named accountability — and accept institutional control
  • Estates and trusts whose lawyers need a counterparty that courts already understand
The wrong choice for
  • Anyone whose core requirement is that no single institution can move the coins — one institution can
  • Privacy-focused holders: the custodian, its regulator, and its subpoena inbox all know your position
  • Small balances: minimums and fees are built for institutions

Our Analysis

Onramp vs Sygnum: What the Data Shows

Onramp and Sygnum both operate in the dedicated custody space, but they take fundamentally different approaches to how your bitcoin is held. In our scoring model, Onramp holds a commanding lead at 90/100 (A) compared to Sygnum at 70/100 (B-). That 20-point gap reflects real, measurable differences in how each platform handles custody, fees, and transparency.

Where Each Platform Wins

Custody and security — the most heavily weighted category in our methodology at 35% — tilts 19 points toward Onramp (97 vs. 78). Onramp eliminates single points of failure in its custody architecture, while Sygnum relies on a model where one compromised entity could put your bitcoin at risk. On fees, Onramp wins by 24 points. Onramp charges $250/mo compared to Custom at Sygnum. Over a multi-year holding period, fee differences compound — a point worth considering for long-term accumulators.

The Custody Question

Here's the key difference: Onramp has no single point of failure (Multi-Institution Custody), while Sygnum does (Regulated Bank). 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.

Bottom Line

Onramp is the clear choice here, outscoring Sygnum by 20 points across our six-category methodology. Keep in mind these platforms target different audiences — Onramp is built for institutions & hnw, while Sygnum serves swiss. One thing to watch with Sygnum: single custodian. swiss jurisdiction only. premium pricing.. The data speaks for itself — but always verify our methodology and do your own due diligence before moving bitcoin to any platform.
