EXPLAINER
How crypto exchanges actually make money, and why it shapes what you see
Trading fees are the visible part. Listing fees, spread capture, interest on balances and liquidations matter more, and they explain a lot of exchange behaviour.
Quick answer
Trading fees, listing fees, spread capture on conversions, interest earned on customer balances, and liquidation revenue from leveraged products. The last three are the least visible and often the largest.
Understanding an exchange’s revenue explains a surprising amount of what it does.
Trading fees
The visible one, usually a fraction of a per cent per side, tiered by volume. Simple, disclosed, and often not the largest line.
Spread on the simple buy button
The one-click purchase flow generally charges a much wider effective price than the order book, and it is presented as convenience rather than as a fee. Users comparing headline fee schedules frequently pay several times more than they think.
Interest on your balance
Fiat balances sitting on an exchange earn the exchange interest. At scale this can rival trading revenue entirely, and it explains why exchanges work hard to keep balances on-platform. It is also a reminder that a balance is a claim on the company, not money you hold.
Listing fees
Projects pay for listings. This creates an obvious incentive problem: the exchange is paid by the party whose asset is being assessed. It is one reason a listing should not be read as a quality signal.
Liquidations
Leveraged products generate revenue when positions are force-closed. That does not mean an exchange engineers liquidations, but it does mean its revenue rises with volatility and with users taking leverage — worth remembering when reading an exchange’s own market commentary.
Why it matters to you
Read the fee schedule for the product you are using, not the headline. Keep balances on-platform only for as long as you need them. And treat listings as commercial decisions rather than endorsements.

Frequently asked questions
Is the simple buy button ever worth it?
For very small purchases where the absolute cost is trivial, or where the order book is genuinely too complex to use safely. For anything material, use the book.
Does a listing mean a project is legitimate?
No. Listings are commercial arrangements. Diligence standards vary enormously and projects generally pay to be there.
