Crypto OTC desks in Miami

Do you actually need a desk?

Most people who ask us about OTC do not need it, and the honest version of this page starts by saying so. An OTC desk is not a status symbol or a way to get a better fee — it is a solution to one specific problem, and if you do not have that problem it will make your life harder rather than easier.

The problem is market impact. A public order book is a queue of bids and offers at different prices. A small market order fills against the best price available. A large one consumes that price level, then the next, then the next, filling progressively worse. The average price you end up paying can be materially different from the price you saw when you clicked, and on a thin trading pair the gap can be severe.

That is slippage, and it scales non-linearly with order size. At $5,000 it is negligible. At $50,000 in a liquid pair like bitcoin against dollars it is noticeable. At $500,000 it is the dominant cost of the trade and it makes every commission argument irrelevant. Worse, a large resting order is visible, which in a market with a great deal of automated participation is an invitation.

A desk removes all of that by taking the other side privately. You state the asset and the size, the desk returns a firm all-in price valid for a short window, and you accept or decline. No partial fills, no public footprint, no discovering your average price afterwards.

How an OTC trade actually works

The mechanics are unglamorous, which is a good sign. A serious desk process looks much more like a private-bank onboarding than like opening an app.

Onboarding comes first, and it is thorough. Expect full identity verification, corporate documents if you are trading through an entity or a trust, and detailed source-of-funds evidence. This is not a desk being awkward: any US firm holding customer money must be registered with FinCEN as a money services business and run an anti-money-laundering programme, and in Florida a custodial operator generally needs a money transmitter licence under Chapter 560 from the Office of Financial Regulation. Having your documents ready is the single biggest determinant of how fast this goes — days rather than weeks.

Then you request a quote. You specify the asset, the direction and the size. The desk returns a firm price, usually valid for somewhere between ten seconds and a couple of minutes depending on the asset and the market. That price is all-in: there is generally no separate commission layered on top, because the desk's margin is the spread.

Then settlement. Both legs move — your dollars one way, the asset the other. Same-day USD settlement is the premium offering and the reason Miami operations centres exist: Trillion Digital advertises direct USD settlement rails with same-day processing out of Miami, covering North and South American markets. More commonly you should plan for next business day, and the binding constraint is almost always your bank rather than the desk.

The Miami landscape

Miami's claim to be a digital-asset financial centre is more substantive than the marketing suggested a few years ago, though the shape of it has changed. The 2021 wave brought announcements — eToro and FTX both said they were expanding into Brickell, with FTX US building space for a small team before the company collapsed entirely. What survived that cycle is quieter and more durable.

Blockchain.com moved its US headquarters from New York to Miami and now occupies a 22,000 square foot space at Cube Wynwd in Wynwood. Trillion Digital runs institutional digital-asset trading with a Miami operations centre providing direct USD settlement across the Americas. Bitstop, founded here in 2013, acquired Genesis Coin and moved that company's headquarters to Miami, making the city the technical centre of the American kiosk software industry. Around those anchors sits a genuine professional layer: crypto-literate law firms, accounting practices, family-office advisers and fund administrators, concentrated in Brickell.

The global desks — Kraken OTC, GSR, Coinbase Prime, Galaxy, Cumberland and others — serve Miami clients too, mostly remotely. That is not a deficiency. OTC trading is a relationship and a phone call, not a location, and the Americas time-zone coverage matters far more than whether the trader is in Brickell or Chicago. What a local presence genuinely buys you is a settlement bank in the right time zone and someone who can sit across a table when the trade is large enough to warrant it.

Spread versus slippage: the only comparison that matters

Retail crypto conditions people to compare percentage commissions. That instinct is useless here, because a desk usually does not charge a commission at all. Its margin is the spread between the price it quotes you and the price at which it can source or offload the asset.

So the comparison is not “0.25% versus 0.4%”. It is “the desk's all-in spread versus the realistic all-in cost of executing the same size on an exchange, including market impact”. Those are different kinds of number and you have to do the work to compare them.

The practical method is straightforward and worth doing before you commit to anything. Get a firm RFQ from the desk for your exact size. Separately, look at the actual order book depth on the exchange you would otherwise use and calculate what your order would average against it. Then add your own time and the risk that the market moves while you work the order in pieces. On a genuinely large trade, the desk usually wins clearly. If it does not, you have learned that your order is not as big as you thought — which is useful information and costs nothing to acquire.

Five questions to ask before you sign anything

A well-designed website is not a counterparty. These five questions, asked directly, will tell you more about a desk than any amount of reading.

Terms you will hear on the call

OTC

Over the counter — a privately negotiated trade between two parties rather than an order placed on a public exchange order book. The price is agreed bilaterally before anything moves.

Slippage

The difference between the price you expected and the average price you actually paid, caused by your order consuming successive levels of the order book. The main reason large orders avoid retail exchanges.

RFQ

Request for quote — you tell the desk the asset and size, it returns a firm all-in price valid for a short window. You either accept or you do not; there is no partial fill at a worse price.

Principal vs agency

A principal desk trades from its own book and takes the market risk. An agency desk works your order into the market for a commission. Principal gives you price certainty; agency can give you a better average on patient orders.

Settlement window

How long between agreeing the trade and both legs actually moving. Same-day USD settlement is the premium offering; T+1 or T+2 is more common.

Source of funds

Documentation showing where your money came from. Every regulated desk will ask, and having it ready is the single biggest determinant of how fast onboarding goes.
