Large bitcoin purchases: quoting, funding and custody

A large bitcoin purchase is arranged with an OTC desk rather than sent to an exchange order book, because an order bigger than the resting offers fills at successively worse prices. You ask a desk for a price on the whole amount, accept or decline it, then fund and settle on the desk's terms. Crypto Loans HQ introduces buyers to desks; it is not a desk.

Key takeaways

• Size is paid in the average, not in a fee. On an order book you pay every level your order consumes, and every fill prints publicly.
• A principal desk's margin sits inside the quote, not in a fee. What you compare between desks is the all-in price against a reference index at the moment you accept, because there is no separate fee line to compare.
• Funding decides who carries whom. Pre-funding leaves your money with the desk; post-trade settlement puts the desk at risk on you. Kraken requires settlement within 24 hours.
• Execution and custody are separate services. Kraken states that its OTC desk “does not custody assets on behalf of trading counterparties.”
• A treasury buys into a fair-valued asset. FASB Update 2023-08 measures in-scope crypto assets at fair value through net income, for fiscal years beginning after 15 December 2024.

Why a large order moves the price against you

An exchange order book is a queue of resting orders at ascending prices. A market order to buy takes the lowest offers first, then the next level, and keeps climbing until it is filled, so the average price you pay is worse than the price on the screen. That gap is market impact, and it widens with your size relative to the depth resting at that moment. Every fill prints publicly, so others can see a buyer working.

A desk takes that job off the order: it quotes one price for the whole amount and sources it itself. Galaxy describes its desk as facilitating risk transfer in a risk-managed way with minimal market impact (Galaxy, accessed September 2026).

How a desk quotes: RFQ, principal and agent

The mechanism is a request for quote. You state the side, the asset, the amount and the settlement currency, and the desk returns a price that stands only for the window it sets, often seconds. Coinbase Prime describes RFQ orders as a way to “request quotes from liquidity providers before executing a trade.” Kraken offers an RFQ portal and a chat route where the trade desk confirms the asset, lot size and price.

What sits inside that price depends on the capacity the desk acts in. Cumberland, a principal, states: “We are a principal trading firm and trade for our own account at our own risk,” charges no fees in that capacity, and prices from “current index prices, market liquidity, volatility, and our overall position in the market.” Kraken says its quoted prices are “all-inclusive.” Coinbase's annual report for 2025 describes Prime as routing customer orders to third-party venues for a transaction fee, the agency pattern. Bitcoin OTC sets out both roles.

Three questions settle most of it before you see a number. Counterparty or agent? How are you paid? How long does the quote stand?

One price, or execution over time

Coinbase Prime lists market, limit, stop-limit, TWAP, VWAP, peg and RFQ order types, and describes a TWAP order as “designed to execute large orders over time to minimize market impact,” with the order “broken down into smaller pieces and executed at regular intervals.” A single quote is certain the moment you accept; a schedule gives an average that may land better or worse, and leaves you exposed while it runs. Neither removes the cost of size.

Funding and settlement: wire, stablecoin and who moves first

Every trade has two legs, the dollars and the bitcoin. Unless something binds them, one side sends first and is owed until the second leg lands.

Pre-funding. You wire the dollars before you trade, so the desk takes no credit risk on you and you carry it while your balance sits there. Gemini contrasts intraday delayed net settlement on its electronic crypto OTC platform with the cost of “pre-funding requirements.”

Post-trade settlement on agreed credit. Cumberland states that “All trades with Cumberland are settled post-trade,” often in less than 24 hours, once you are approved as a counterparty, with API trades netted in a 24-hour roll-up. Kraken lets eligible clients settle within 24 hours.

Delivery versus payment. In principle each leg is released only against the other. No desk named here publishes such a mechanism, so treat it as a question to ask, and get the sequence in writing.

The dollar leg runs on bank hours. The Fedwire Funds Service day ends at 7:00 p.m. Eastern Time, customer transfers cut off at 6:45 p.m., and all Saturdays and Sundays are holidays, as of September 2026; the Federal Reserve Board announced on 9 October 2025 that the service will add Sundays and weekday holidays, no earlier than 2028. Bitcoin settles at any hour, so a purchase agreed late on a Friday can leave one leg waiting until Monday.

Funding in stablecoins removes the banking day but adds an issuer. The GENIUS Act (Public Law 119-27, approved 18 July 2025) creates a US framework for payment stablecoins, but it is not yet in effect: we found no final regulator rule as of 19 September 2026.

Onboarding and the documents a desk asks for

No desk quotes before it has onboarded you, and most questions are about the money rather than the coins. Two are specific to a purchase.

• Source of funds for the dollars. Where the money comes from, evidenced rather than asserted: sale proceeds, a financing, a distribution, an income history. UK regulations require firms to establish source of wealth and source of funds for politically exposed persons (regulation 35), and firms apply similar checks more widely on a risk basis.
• The settlement account. Kraken states that the name on your bank account has to match the name on your Kraken account, so pay from an account in the trading entity's own name. Some desks face institutions only: B2C2 states that it “does not transact with or provide any service to any retail investor or consumer.”

The rest is standard: identity, beneficial ownership at 25 percent or more with one controller (31 CFR 1010.230), and prescribed sender and recipient details travelling with any US transmittal of US$3,000 or more (31 CFR 1010.410(f)). What each client type is asked for is on how it works. Onboarding takes days, so start before the price you want appears.

Custody immediately after the purchase

The commonest gap in a first large purchase is that the buyer solves execution and leaves custody to the last hour. They are different services: Kraken states that its OTC desk “does not custody assets on behalf of trading counterparties.” Three routes are usual.

1. An account with the desk or an affiliate

   Simplest to settle into, and the exposure is to that firm until you move the coins. A balance left with a venue is a claim on it, not a holding in your name.

2. A third-party custodian

   “Qualified custodian” has a defined US meaning under the SEC custody rule (17 CFR 275.206(4)-2(d)(6)), and firms use the phrase more loosely than the rule does. Ask which limb applies.

3. A wallet you control

   Single-signature or multisig, held by you or with a key agent. Nobody can move the coins without your key, and nobody reimburses you if it is lost. Bitcoin loan rehypothecation and custody covers these structures.

Test the route first: a small transfer, a confirmed address, then the balance.

Buying for a company treasury

Authority. A desk will want a board resolution or equivalent and an authorized signatory list. Decide in advance who may request a quote, who may accept one and who may instruct a transfer, and keep those three roles apart.

Accounting. The US position changed with FASB Accounting Standards Update 2023-08, issued 13 December 2023, which added Subtopic 350-60. An entity “shall measure crypto assets at fair value in the statement of financial position,” and gains and losses from remeasurement “shall be included in net income.” It is effective for fiscal years beginning after 15 December 2024. Its six scope conditions cover an intangible asset that gives no enforceable claim on other assets, sits on a distributed ledger, is secured by cryptography, is fungible, and is not issued by the reporting entity or a related party. Bitcoin is generally understood to meet all six, but that assessment is the reporting entity's and its auditor's.

So the purchase price is an entry into a fair-valued asset, not a cost carried until sale: every reporting date moves the carrying amount and the income statement. A treasury that would rather keep its cash has bitcoin treasury financing; the other side of the desk relationship is selling bitcoin OTC.

Risk

Risks in a large bitcoin purchase

• Counterparty risk. With a principal desk, the desk is the other side of your trade. If you pre-fund and it fails before it delivers, you are its creditor. Any balance left with the desk or an exchange carries the same exposure.
• Settlement risk. Bitcoin sent to a wrong or substituted address cannot be recalled, and the FTC warns that cryptocurrency payments typically cannot be reversed. Agree in writing who sends first, by when, and to which address and account.
• Impersonation and altered payment instructions. California's Department of Financial Protection and Innovation reports in its Crypto Scam Tracker that “Imposter websites are one of the most common reported scams” (accessed September 2026). In its business email compromise advisory the FBI's IC3 tells recipients to use secondary channels or two-factor authentication to verify requests for changes in account information (PSA I-091124-PSA, 11 September 2024), and the same discipline applies to a desk's settlement instructions. Treat a late change to an address or wire instruction as fraudulent until you confirm it by voice.
• Price risk inside the window, and recovery scams after a loss. A quote stands for a short, stated period; let it lapse and the next price is a new price. If money is lost, note that the CFTC calls fraud-recovery scams “a form of advance-fee fraud,” and the IC3 states that it does not recover funds through Facebook, Telegram or similar platforms.

The warning signs that separate a desk from an impersonator are in what is OTC bitcoin trading.

Large bitcoin purchases: questions

Why not place a large order on an exchange instead?

Because the order fills against whatever rests in the book: once the lowest offers are taken, the rest fills at higher prices, and every fill prints publicly. A desk instead quotes one price for the whole amount. Coinbase Prime describes its scheduled orders as designed to minimize market impact.

How do you pay for a large bitcoin purchase?

Usually by bank wire from an account in the same name as the trading account, and sometimes in stablecoins. Some desks want the money before they trade; others settle afterwards on agreed credit. Cumberland settles post-trade, often in under 24 hours, and Kraken requires settlement within 24 hours.

Where should the bitcoin go once the trade settles?

Decide before you trade, because execution and custody are separate services. Kraken states that its OTC desk does not custody assets on behalf of trading counterparties. The choices are an account with the desk or an affiliate, a third-party custodian, or a wallet you control.

How does a company account for bitcoin bought for treasury?

In the United States, FASB Accounting Standards Update 2023-08 added Subtopic 350-60. Crypto assets in its scope are measured at fair value, with remeasurement gains and losses in net income, for fiscal years beginning after 15 December 2024. Bitcoin is generally understood to meet the six scope conditions, but the assessment is the reporting entity's and its auditor's. Confirm the treatment with your auditor.
