Crypto OTC Desks in Florida

Why large orders cost more than the fee

Every exchange displays a price. That price is the best available offer for a limited quantity — the top of the order book. Behind it sit progressively worse offers.

When you place a small market order, you fill entirely at or near the top and the displayed price is roughly what you pay. When you place a large market order, you consume the top level, then the next, then the next. Your average fill price ends up worse than the price you saw. That difference is called slippage, and three things about it matter enormously.

• It is not itemised. No statement line says "slippage: $3,200". You simply received less crypto than the screen implied.
• It scales non-linearly. Doubling your order size can more than double the slippage, because you go deeper into thinner liquidity.
• It can dwarf the trading fee. A 0.25% fee on $500,000 is $1,250. Slippage on the same order, depending on venue and moment, can be several times that.

There is a second, subtler cost. A large order visible in public order-book data signals your intention to everyone watching, including automated systems whose entire business is reacting to exactly that signal. Desks settle bilaterally, so nothing you did appears in public data.

When a desk beats an exchange, and when it does not

Note the middle row honestly: between $25,000 and $100,000 a patient buyer with a licensed exchange account and a willingness to place limit orders over a day or two will often match a desk. The desk's value there is convenience and a single settlement, not necessarily price.

Where Florida's OTC desks actually are

Florida's OTC activity is concentrated far more tightly than its kiosk network, and almost all of it is in Miami.

We list categories and publicly stated corporate addresses rather than making recommendations. Desk personnel, minimums and capabilities change frequently. Verify any desk's current licensing yourself before contacting it.

How an OTC desk transaction actually works

1. Onboarding. Full identity verification, and corporate documents if you are trading through an entity — formation documents, beneficial ownership, authorised signatories. Expect source-of-funds questions. This takes days, not minutes, so do it before you need to trade.
2. Request for quote. You state the asset, the size and the direction. The desk quotes a firm price, usually good for a short window measured in seconds or minutes because they are hedging their own exposure.
3. Acceptance. You accept or decline. There is no partial fill and no negotiation once the quote is live — that is the point of a firm quote.
4. Settlement. Typically same-day. Funds by wire, crypto delivered to a wallet address you specify. For a first trade, most desks settle in one direction first rather than simultaneously — clarify the sequence in writing before you commit.
5. Confirmation. You receive a written trade confirmation showing asset, quantity, price, all-in cost, settlement details and the transaction hash. Keep it. You will need it for tax basis and, if you hold a security clearance or a regulated role, for documentation.

Due diligence before you send anything

You are about to wire a large sum to a counterparty on the strength of a phone call. Spend an hour first.

• Verify the licence. Search the entity in NMLS Consumer Access and in the Florida Office of Financial Regulation money transmitter records. Match the exact legal entity name on the wire instructions, not a trading name.
• Confirm the physical office. A real desk has one. Visit it if the trade is large. A firm that will only meet in a hotel lobby or a coffee shop is telling you something.
• Check for enforcement history. Search the entity and its principals on Investor.gov, the SEC and CFTC enforcement databases and the Florida Attorney General.
• Insist on a written trade confirmation before settlement, not after.
• Verify wire instructions by voice on a number you obtained independently — not from an email. Business email compromise targeting exactly this moment is one of the most successful frauds in existence.
• Do a small first trade. Even at the cost of two sets of fees, a $10,000 test before a $500,000 block is cheap insurance on a new relationship.

The DIY alternative: working the book yourself

You do not have to use a desk. For amounts between roughly $25,000 and a few hundred thousand, a patient buyer on a licensed exchange can achieve a similar outcome.

• Split the order. Ten limit orders of $25,000 placed over a day or two will usually fill closer to mid than one $250,000 market order.
• Use limit, never market. A market order at size is precisely the mistake this page exists to describe.
• Post as a maker. Maker fees are lower than taker fees on every major venue — CEX.IO is 0.16% maker against 0.25% taker — and a resting limit order that gets filled pays the maker rate.
• Avoid thin hours. Liquidity is worst in the early hours of Sunday morning US time. Slippage is worst exactly then.
• Check depth before you size. Most exchange order books show cumulative depth. If your order is a meaningful fraction of the visible book, it is too large for one market order.

This approach costs more of your time and less of your money. Whether that trade is worth it depends on the size and on how much you enjoy watching order books.

Tax and record-keeping for large trades

Florida charges no personal income tax, so a large gain realised as a Florida resident carries no state tax — and no state estate tax either. That is a genuine, lawful advantage and a substantial part of why so much crypto wealth has relocated to Miami, West Palm Beach and Naples.

Federally, none of it changes. For a large OTC transaction, three things matter.

• Basis documentation. The trade confirmation is your evidence of cost basis. For a purchase, keep it permanently — you may not sell for a decade. For a sale, it establishes proceeds.
• Holding period. The one-year boundary between short-term (ordinary income rates) and long-term (0%, 15% or 20% plus potential 3.8% Net Investment Income Tax) is worth real money at this size. Know the acquisition date of every lot.
• Reporting. US brokers began issuing Form 1099-DA for the 2026 tax year. Desk transactions may be reported differently from exchange transactions depending on the counterparty's status, so ask what you will receive and when.

At six and seven figures, this is not a spreadsheet exercise. Use a CPA who has handled digital assets before, and involve them before the trade rather than the following April — lot selection and timing decisions cannot be made retroactively. Our Florida tax guide covers the framework.

One more thing at this size: custody. A seven-figure position sitting on an exchange with SMS two-factor authentication is not an arrangement any professional adviser would accept for another asset class. Self-custody with a steel-backed recovery phrase, multi-signature arrangements, or a qualified custodian — and a documented succession plan lodged with your estate attorney. See our wallet guide.
