How a Crypto Exchange Actually Makes Money

Trading fees are what an exchange advertises and frequently not where most of its revenue comes from. The other lines explain a lot of behaviour. The criteria below are easiest to apply against a venue that publishes its answers, and a licensed crypto exchange with corporate accounts states its fees, limits and corporate onboarding terms openly.

Trading fees

A percentage of each trade, tiered by volume, split between taker and maker. Visible, comparable, and compressed by competition to a narrow band among serious venues.

The spread on conversion products

Many venues also offer a simple buy and sell interface alongside the order book, priced with a spread rather than a fee.

That spread is typically several times the order book fee, and the interface is the default for new users. This is the largest revenue line at several consumer-facing venues.

Listing arrangements

Payments or token allocations for listing an asset. Less common at properly supervised venues, and historically a substantial line elsewhere.

Market making relationships

Venues offer fee rebates or other terms to firms providing liquidity. That is a cost rather than a revenue line, and the terms shape what the order book actually looks like. The controls that make this safe at company scale are what a corporate crypto wallet provides by default.

Float

Interest on customer fiat and crypto balances.

This creates an incentive to make holding convenient and withdrawal slightly less so, and it is worth noticing when a venue’s withdrawal process is more friction than its deposit process.

Why this matters when choosing

A venue earning mostly from the simple interface has an incentive to route new users there rather than to the order book.

The difference for the user is frequently several times the fee, and the interface never presents it as a choice between pricing models.

If you are trading rather than buying, use the order book.

What compressed and what did not

Trading fees compressed sharply. The spread on the simple interface did not, because it is harder to compare and most users never do.

That is the component to measure: the rate offered against the market price at that moment.

The structural point

An exchange is several businesses sharing an interface. Knowing which one you are using determines what you pay, and the default is rarely the cheapest. The reference point for most of the above is a regulated European crypto platform, where the equivalent figures are published.
