KuCoin vs OKX.

We don't hand out safety verdicts — we keep a sourced record. On Skontro's Reliability Score, OKX currently scores higher (84 vs 73 of 100). The score compresses documented withdrawal reliability, proof-of-reserves practice, regulatory standing, security history, support quality and maturity into one number, with every negative data point dated and sourced, and older incidents decaying over 24 months.

The component-level basis — which incidents, which licences, which proof-of-reserves cadence — is one click away on each venue's page. Read the dated record for KuCoin and OKX there before weighing the one-number summary; the score is a compression, not a substitute for the sources behind it.

Full sourced basis, incident by incident: KuCoin · OKX.

KuCoin publishes 0.10% maker / 0.10% taker on its base tier; OKX publishes 0.08% maker / 0.10% taker on its base tier. On the taker tier the two are level — but the published fee is only one part of the real cost. The other part is the spread your order actually crosses in the live orderbook, a number that exists on no fee page. The cards above measure it for the same €1,000 Bitcoin buy on both venues, timestamped; the ranking can flip between measurements as books move.

Where a venue publishes a fixed BTC withdrawal fee, the live cards include it; where it doesn't, the total honestly excludes withdrawal and says so — a passthrough network fee shown at withdrawal time is a data point, not a gap. For your own size and asset, the live comparison recomputes everything in real time.
