How to judge an exchange, and what a review cannot tell you

We are going to start with an admission, because it shapes everything that follows. Coinpric does not currently publish exchange reviews with scores, and this article explains the reasoning rather than working around it. The short version is that the most decision-relevant facts about an exchange are not observable from the outside, and a score built only from the observable ones creates false confidence in precisely the wrong direction.

What a review can genuinely establish

Plenty is checkable, and worth checking:

• Published fee schedule — the maker and taker rates, tiering, deposit and withdrawal costs.
• Asset selection and pairs — what is listed and what it can be traded against.
• Observable liquidity — visible order-book depth, and the spread at a given size.
• Interface and reliability — measurable over time, including during volatile sessions.
• Licensing status — verifiable directly against a regulator’s public register.
• Stated custody arrangement — who holds assets, in what proportion, per the exchange’s own claims.
• Documented incident history — outages, halts and losses that became public.

A review covering these honestly is useful. Note that all of it describes the product, and the risks that ruin people are not product risks.

What no reviewer can see

Here is the gap, stated plainly.

Whether assets exist in the stated amount. A reviewer sees a balance in an interface. That is a database row. Whether the corresponding assets are actually held, unencumbered, is not observable from outside — and historically, when exchanges have failed, this is the thing that was wrong.

Whether customer assets are segregated. An exchange can hold enough in aggregate while commingling customer funds with its own operations, so a loss elsewhere in the business becomes a customer loss. From the outside, a healthy exchange and one quietly running a deficit look identical.

Whether affiliated entities are lending the assets. Group structures can be complex enough that customer assets support activity in a related company. This is not visible in an interface and frequently not visible in financial statements either.

How withdrawals behave in a crisis. Withdrawals work smoothly right up until the moment they do not, and the transition is often a matter of hours. A review conducted in calm conditions tells you nothing about this.

Concentration and counterparty exposure. Where an exchange’s own risk sits — which lenders, which market makers, which banks — is essentially never disclosed.

The one partial answer: proof of reserves

Some exchanges publish cryptographic attestations letting customers verify their balance is included in a total, and demonstrate control of addresses holding that total. This is a real improvement and worth seeking out. But understand exactly what it does and does not cover:

The core limitation: assets are provable on-chain, liabilities generally are not. A proof of reserves without a corresponding proof of liabilities shows that assets exist, not that they are sufficient. Some schemes address this; many do not, and the difference is rarely explained in the announcement.

What to actually check yourself

Verify the licence at the source. Do not accept a logo on a website. Regulators publish searchable registers; find the entity name and confirm it, and check that the licensed entity is the one you will actually contract with. Group structures sometimes route customers to a different company from the licensed one.

Read the terms for the custody language. You are looking for whether assets are held in trust or as the exchange’s property, what happens to you in insolvency, and whether the exchange may lend or pledge your holdings. This is usually stated, and almost never read.

Test a withdrawal early and small. Before size matters, confirm the path works end to end. Also confirm the limits, because they are frequently far lower than the deposit limits.

Look for the specific failure of transparency. Not “is there marketing”, but: is the legal entity named, is a jurisdiction stated, is there an auditor, and are the reserve attestations recurring rather than one-off?

The conclusion we actually hold

Exchange risk is not primarily a choice between good and bad venues. It is a structural consequence of holding assets at a venue at all — you are exposed to that company for as long as your assets sit there, and no amount of interface quality changes that.

Which points at the only mitigation that does not depend on trusting a review: reduce the exposure. Hold at an exchange what you need there for trading and settlement, and hold the rest where the failure of any single company cannot reach it. We cover what that involves, honestly including the new risks it introduces, in what “not your keys, not your coins” really means.

When we do publish exchange assessments, they will state which claims we verified, how, and on what date — and they will say plainly which risks remain unobservable. Our editorial guidelines and affiliate disclosure set out the commercial position: there are currently no affiliate relationships on this site, and a commercial relationship will never move an assessment.
