Client Notes
What traders noticed after sitting through a fee and spread comparison—specific desks, not star widgets.
Short notes
“We thought the KRW–USDT route was clear until they lined up withdrawal fees next to the spread. The gap shrank by half—uncomfortable, but I stopped chasing ghosts.”
“The calculator sheet they left on my second monitor still gets opened before I move size. Not flashy; just the columns I kept forgetting.”
“Audit found my account was still on the old maker tier while the public page showed VIP-2. That mismatch alone was worth the invoice—though I wish we had caught it a month earlier.”
“Monthly checks are dry by design. Once the fee cells were wrong after an exchange update; they fixed the sheet and we moved on. I would not call it exciting.”
Longer desk story: two venues, one rainy Thursday
Brief
A Yeoksam client ran BTC between a KR-facing book and an offshore book, convinced the mid-day spread covered both taker fees. Screenshots looked persuasive. We booked a 90-minute review.
Constraint
Withdrawals on the KR side had a bracketed fee that only appeared after selecting the destination network—easy to miss when copying from a blog table.
Work
We rebuilt the round trip on their PC calculator: entry taker, exit taker, bracketed withdrawal, deposit credit delay assumed as opportunity cost for half a day. The headline spread stayed; the net edge flipped negative on the size they preferred.
Outcome
They cut that route for two weeks, waited for a VIP step-down on one venue, then asked for a follow-up check. No victory lap—just a quieter desk and a worksheet with the bracket line permanently visible.
