Treasury management between club fees — OKX VIP review

Private club member + custom-fit gear habit. The fee math compounds: initiation, monthly, locker, range, plus the equipment cycle. Started parking pre-allocated cash on OKX (https://okx.com/join/CODE777, code CODE777 = 50% off trading fees). VIP fee schedule is sub-bps once you ramp, OTC desk for bigger fills, Proof-of-Reserves quarterly. Anyone else here run a tier-1 venue for non-fiat cash management?
