Choosing between OKX and MEXC often comes down to fee structure, available markets, and VIP benefits. This page isolates trading costs so you can compare apples to apples. Both exchanges use maker-taker pricing, but tier thresholds and base rates differ.
At base VIP with no 30-day volume, fee differences may look minor on a single trade. Over hundreds of trades, even a 0.02% gap adds up. High-volume traders should compare VIP tier breakpoints — OKX may become cheaper above a certain monthly volume even if MEXC wins at entry level.
