Crypto OTC Trading Platform or Exchange: Choosing per Trade

This is not a choice of venue for your business, it is a choice per trade. The same company should use both, and the decision each time comes down to three questions. Most of what follows is checkable against an OTC crypto desk rather than taken on trust.

Question one: how large is the order relative to visible depth

Open the order book on the venue you would use. Add up the resting liquidity within half a percent of the mid price on the side you need.

If your order is under about a tenth of that, the book is fine. Between a tenth and a half, consider splitting over time or using a desk. Above half, use a desk.

This is the primary determinant and it is measurable in thirty seconds.

Question two: does it need to happen now

If you can work an order over hours using limit orders, the book becomes viable at larger sizes because you are supplying liquidity rather than consuming it. You may even earn the maker rebate rather than paying the taker fee.

If it needs to be done in one action at a known price, a desk is the answer regardless of size considerations.

Question three: does anyone need not to see it

A large visible order signals intent. For a fund rebalancing, a treasury operation, or anything where being seen changes the price, the book is disqualified independent of cost.

A desk trade is not public. That discretion is part of what the spread buys.

The cost comparison worked through

Take a two million euro purchase of a major asset.

On a book: taker fee at 0.1 percent is 2,000 euros. Slippage walking the book, depending on depth and conditions, realistically 0.15 to 0.6 percent, so 3,000 to 12,000 euros. Plus the risk that other participants react. Total 5,000 to 14,000 euros, with meaningful uncertainty.

Through a desk: a quoted spread of 0.15 to 0.35 percent against mid, so 3,000 to 7,000 euros. Known before you commit.

The desk is usually cheaper at this size and it is always more certain. At two hundred thousand euros the comparison inverts and the book wins clearly. Merchants meet this from the other direction, and an exchange that publishes its full fee schedule is the usual answer there.

What a desk cannot do

Fill you at the touch on a small order. The desk’s minimum is usually somewhere in the tens or hundreds of thousands, and below that they are not interested.

Provide continuous execution. A desk is a series of discrete trades, not a venue you sit on.

Offer the tightest possible price on a small liquid trade. The book will beat them every time there.

What an exchange cannot do

Give you one price for a size that exceeds its depth.

Keep the trade private.

Guarantee a fill at a known price. A limit order might not fill; a market order fills at an unknown average.

The operating pattern that works

Small and routine: exchange, limit orders, take the maker side where possible.

Large or urgent or sensitive: desk, two quotes, compare as a percentage against mid.

Recurring large flow: a relationship with one or two desks, which improves pricing over time, plus exchange execution for the smaller pieces.

Most companies that do this well end up with both a crypto OTC desk relationship and an exchange account, and they use whichever suits the specific trade rather than defaulting to one.

The mistake to avoid

Splitting a genuinely large order into many small ones to avoid a desk. It feels clever and it is usually more expensive, because each piece moves the market a little and the market does not forget between pieces. If the total is large relative to depth, the total is what matters, not the pieces.
