Commission Free Crypto Trading: Which Exchanges Actually Charge $0

Yes — genuinely commission-free crypto trading exists in the exchanges we track. Bitfinex charges 0% maker and 0% taker on spot trades^††, confirmed directly on its own fee-schedule page, and its current tagline says as much: "The Original Bitcoin Exchange - Now with zero trading fees"^†. MEXC gets close on one side only — 0% maker but 0.05% taker^†† — so it's commission-free for limit orders and not for market orders. Scope that answer carefully: "commission-free" here means the trading fee only. We have no withdrawal-fee, spread, or deposit-fee data for either platform, so this page can't tell you whether either exchange is cheap to use overall — only that the commission line on the fee schedule can genuinely read $0.

Which Exchanges Actually Charge Zero Commission?

Sorted cheapest to priciest by round-trip trading cost, regular non-VIP tier. A maker order adds liquidity to the order book — a limit order sitting unfilled until someone else trades against it. A taker order removes liquidity — a market order, or a limit order that fills immediately against an existing one. Exchanges typically price the two differently, which is why a platform can be commission-free on one side and not on the other.

Bitfinex is the only exchange of the five with $0 on both maker and taker sides^††. MEXC is $0 only on the maker, limit-order side; its 0.05% taker fee^† means a market order there is not commission-free. OKX (0.08% maker, 0.1% taker)^††, Binance (0.1% maker, 0.1% taker)^††, and Kraken (0.4% maker, 0.8% taker)^†† all charge a commission on both sides of a trade, in our tracked data.

What Does a Round-Trip Trade Actually Cost?

A round trip means one buy and one sell, both filled as taker (market) orders — the fee applies twice.

The math is taker fee times two sides times trade size. On Bitfinex that's 0% x 2 x $2,000 = $0^†. On MEXC it's 0.05% x 2 x $2,000 = $2^†. On OKX and Binance it's 0.1% x 2 x $2,000 = $4 each^††. On Kraken it's 0.8% x 2 x $2,000 = $32^† — the identical $2,000 trade costs $32 more in commission on Kraken than on Bitfinex, purely from which exchange it's placed on.

The gap scales with trade size, not just with the exchange you pick. A trader running the same round trip at $20,000 instead of $2,000 would see the Bitfinex-to-Kraken commission gap move from $32 to $320^††, because both sides of that comparison are percentages, not flat fees. That's the trading-fee side of the cost only — it says nothing about withdrawal fees or spread, which aren't in this data for any of the five exchanges.

What "Commission-Free" Doesn't Tell You

A zero-commission line is not the same thing as a zero total cost. We have no withdrawal-fee, spread, or deposit-fee data for any of the five exchanges on this page — not for Bitfinex, not for MEXC, not for the other three. We're not going to guess at what isn't in front of us: it would be easy to assume a platform charging a zero trading-fee rate must be making up the difference somewhere else, in a wider bid-ask spread for instance, but that's a plausible pattern in the industry in general, not a sourced fact about Bitfinex specifically, so we're stating it as "not sourced here" rather than as a finding. If you want the full cost picture — commission plus whatever else applies at your trade size — run your own numbers through our fee calculator once you've pulled the missing pieces (withdrawal fee, spread) from the exchange directly.

Why "Zero Commission" Headlines Get Marketed So Hard

Our trading knowledge base treats a trader's results as an iceberg: the visible 30% is whatever gets an instant, easy-to-see reward — clicking buy and sell, reading a chart, comparing a fee schedule across five browser tabs — while the submerged 70% is the unglamorous work that pays nothing today and is exactly what most results actually come from . A "zero commission" headline is the marketing-side version of that same visible 30%: it's a single number, easy to screenshot, easy to compare, easy to put in a tagline — which is exactly why an exchange with a genuinely competitive rate leads with it, the way Bitfinex's own tagline calls itself "Now with zero trading fees"^†. That doesn't make the number false — Bitfinex's 0%/0% is real, and it's sourced directly from the exchange's own fee page^††. But the total cost of actually using a platform — withdrawal fees, spread, how deposits and support behave when something goes wrong — is the invisible 70% that a fee-schedule headline was never built to show you, the same way a price chart was never built to show you the discipline behind the trade that moved it. Reading a fee page for one number is not a substitute for reading the full cost of a platform, the same way watching a chart is not a substitute for the routine that decides whether a trade should have been taken at all.

FAQ

Is Bitfinex really free to trade on?

Bitfinex charges 0% maker and 0% taker on spot trading, confirmed on its own fee page^††. That covers the trading commission only — we don't have sourced data on Bitfinex's withdrawal fees, deposit fees, or spread, so we can't say whether the platform is free to use overall.

Is MEXC commission-free too?

MEXC is $0 on the maker, limit-order side but charges 0.05% taker on market orders^††, so it's commission-free only for orders that add liquidity to the book, not for orders that take it.

Why do OKX, Binance, and Kraken charge a commission at all?

In our tracked data, OKX charges 0.08% maker and 0.1% taker^††, Binance charges 0.1% maker and 0.1% taker^††, and Kraken charges 0.4% maker and 0.8% taker at its entry tier^††. None of the three is $0 on either side.

Does zero commission mean the platform is cheaper overall?

Not necessarily, and we can't say either way from what we have. We have no withdrawal-fee, spread, or deposit-fee data for any of the five exchanges compared here, so a zero-commission line tells you about the trading fee only, not the total cost of using the platform. Run your own numbers through our fee calculator once you have those additional figures from the exchange directly.

Which of these five exchanges is best overall?

This page is scoped to trading commission only, so we're not ranking these five overall — that would require factors like security, regulation, and country availability that go beyond commission data. See our best crypto exchanges list and methodology for how we evaluate the fuller picture.
