What to compare when choosing between crypto exchanges

“Which exchange is best” is a question with no answer, because the venues differ along axes that matter enormously to some people and not at all to others — and any single ranking has to pretend otherwise, usually while being paid to.

“What should I compare” does have an answer. It is five questions, and the order matters more than the list, because settling the early ones removes most of the field before you have to think about the later ones.

1. What is it permitted to do, and by whom

Not whether it says “regulated” — what the permission actually is.

In most countries the answer is a registration for anti-money-laundering supervision, which imposes identity checks and reporting and says nothing about how client assets are held or what happens if the firm fails. The EU’s regime is the exception that authorises the activity itself. What a regulated exchange is regulated for works through the three major jurisdictions; the summary is that the word is doing far less work than it appears to, and that checking the register takes two minutes.

Do this first because it is the only one of the five that can eliminate a venue outright.

2. Can you get everything out

The leaving test, and the most informative thing you can do with a new account.

Deposit a modest amount, buy something, sell it, and withdraw the proceeds all the way back to your bank — then do the same with a crypto withdrawal to an address you control. Note how long each leg took and what it cost.

You have now measured the property that matters most on the day it matters most, at a moment when nothing is wrong. A venue that is slow or obstructive about withdrawals in calm conditions is not going to improve under stress, and that is information no review can give you because reviewers rarely try to leave.

It also surfaces the exit costs that never appear in a comparison — the withdrawal fee is usually a policy number rather than a pass-through, and a venue that makes leaving expensive has an interest in you staying.

3. What it costs you, measured rather than read

The published schedule is accurate and incomplete. The two largest components of a round trip — the spread, and which of the venue’s own surfaces you used — are not fees, so they are not on the fee page.

The measurement that includes everything is the round trip you already ran in step two. Compare what came back with what went in. That single number covers the commission, the spread, the rails and the exit, at your size and with your funding method, which is the only version of the question that concerns you.

4. Whether the market is deep where you trade

Relevant in proportion to what you buy and how much.

If you hold two or three major assets in modest size, almost any established venue is deep enough and this question can be answered “yes” and skipped. If you trade size, or anything outside the largest pairs, the order book is public and depth is the thing to read, not volume — volume is self-reported, feeds rankings worth money, and has a long documented history of being inflated.

5. What it tells you about itself

Last, because it is the softest — and still worth something.

Published reserve attestations, a named legal entity per region, clear statements about which entity serves your country, and documentation of what happens to client assets in an insolvency. More disclosure is better than less, but read it for what it actually claims: an attestation of assets without liabilities is not a solvency statement, and most of them stop at assets.

Why “most recommended” is the weakest signal

Almost every “best exchange” table you have read was paid for by at least one entry in it. That is not cynicism; it is the business model of the format — affiliate commissions on sign-ups are the reason the genre exists at such volume, and the ordering follows the payouts more often than it follows the analysis.

The same applies, in a quieter way, to expert preference. Traders recommend the venue that suits their strategy and size, which may have nothing to do with yours; a professional’s pick optimises for fee tiers and API behaviour that a monthly buyer will never touch.

This publication takes no commission from any venue it writes about, which is what makes it possible to measure these brands and write about them in the same place. It is also why you will not find a ranked list here.

The order, restated

Permission, then exit, then cost, then depth, then disclosure. Most people reverse it — they start with the fee table and the recommendations, which are the two least reliable inputs available, and never run the one test that would tell them something the venue did not choose to say.

Run the leaving test. Everything above it in the list is a matter of reading; that one is a matter of finding out.
