Two checks — cost and trust

Binance vs OKX.

Two different questions decide this matchup: whether you get your money out, and what a trade really costs. Below, each venue’s sourced Reliability Score sits beside the measured all-in cost of the same €1,000 Bitcoin buy — trading fee plus the hidden spread from the live orderbook, withdrawal included where the venue publishes one — measured 2026-07-29 07:48 UTC.

On reliability, Binance scores 72, OKX 84 (of 100, sourced & dated). OKX currently carries the higher score — cheapest and safest need not be the same venue.

At this measurement, the same €1,000 BTC buy cost €1.01 all-in on Binance vs €1.00 on OKX. Moments and sizes change the answer — the live comparison recomputes for your exact trade.

Which is safer?

On proof of reserves, OKX publishes a monthly Merkle-tree proof with published on-chain wallets, Hacken engaged for verification and open-source tooling. Binance self-publishes a regular Merkle-tree proof with zk-SNARKs and on-chain wallet disclosure (January 2026 snapshot: BTC ratio 100.06%) — without an independent auditor’s sign-off. Monthly-and-verified versus regular-and-self-published is the attestation gap to understand here.

Both venues carry major resolved US enforcement, one year apart. Binance: guilty plea and $4.3B DOJ/FinCEN/OFAC/CFTC resolution (November 2023); SEC civil suit dismissed with prejudice May 2025; no MiCAR licence verified as of the 2026-06-10 research pass, with a Greek application pending. OKX: guilty plea to operating an unlicensed money-transmitting business with over $504M in forfeiture and fines (February 2025) and a compliance consultant retained through February 2027 — but on the EU side it was among the first with a MiCAR CASP licence (Malta MFSA, announced 2025-01-27), later adding MiFID II; Malta’s FIAU fined its European subsidiary ~€1.05M in April 2025 for historic AML failings, with remediation noted by the regulator.

Operationally, OKX (roots in OKCoin, 2013) has no platform outages documented in the last 24 months of the research pass; a June 2024 incident drained a small number of individual accounts via SIM/identity-theft attacks and was compensated, with no platform-level compromise. Binance paused withdrawals for ~23 minutes during the 2025-04-15 AWS outage and paid $283M in compensation within days of the 2025-10-10 crash-day depegs. The live scores above fold all of this into one sourced number per venue — the component table shows where they differ.

Which is cheaper?

Published base-tier fees and the measured all-in cost of the same €1,000 BTC buy are in the live cards above — the spread portion is a property of each orderbook at measurement time, not a constant. Structurally, both venues publish a fixed BTC withdrawal fee (shown live above from their published schedules), so the withdrawal leg enters both totals on equal terms. The ranking is by what you actually receive — never by affiliate relationship — and your own order size may rank them differently on the live tool.

Method, in one paragraph

We walk each venue’s live public orderbook for the exact order size, add the published base-tier fee and the venue’s published withdrawal fee, and rank by what you actually receive. Venues without fresh data are omitted, never faked. The Reliability Score is sourced and dated, and never part of the cost ranking — and ranking is never influenced by affiliate commissions.
