What is OTC bitcoin trading?

A definition, a comparison with an exchange order book and a peer-to-peer marketplace, how a desk builds a quote, what desks publish, and how to tell one from an impersonator.

What is OTC bitcoin trading? It is buying or selling bitcoin bilaterally with a desk, which quotes one price for a set amount and settles directly with you, instead of posting orders to a public exchange order book. It is not #bitcoin-otc, the legacy peer-to-peer marketplace on an IRC channel, which says it is only an aggregator of supply and demand.

Key takeaways

  • One price, one counterparty, no public print. The trade is a bilateral contract, not a queue of fills, and nothing appears on the exchange tape as it executes.
  • The desk is either your counterparty or your agent. Cumberland states that it trades “for our own account at our own risk”; Coinbase's 2025 annual report says Prime routes orders to third-party venues for a transaction fee.
  • Most institutional desks publish no minimum. Kraken's own pages give two figures, US$50,000 and US$100,000; Cumberland, Galaxy, FalconX and B2C2 publish none.
  • Settlement within 24 hours is the published norm at Cumberland and Kraken. Custody is separate: Kraken states that its OTC desk does not custody assets for counterparties.
  • Impersonation is the dominant fraud. California's financial regulator reports that imposter websites are among the most common scams in its tracker.

The definition, and the three things that follow from it

“Over the counter” means away from a venue's central order book. Instead of adding an order to a public queue and taking whatever fills arrive, you ask one firm for a price on a stated amount, and you either accept it or you do not. Everything else follows from that.

Price formation. An order book prices by queue: your order consumes resting orders level by level, and the average depends on how much was resting. A desk prices by quote: one number for the whole amount, which it must then source or hedge at its own risk.

Disclosure. Exchange fills print to a public trade record. A bilateral trade does not, at least until the desk hedges. For a holder moving size, that difference is the product.

Settlement. An exchange settles inside its own system. A bilateral trade settles on terms the parties agree: who sends first, in what currency, by when, and on what credit.

The label covers a range. At one end is a voice or chat desk where a person quotes; at the other, an electronic request-for-quote platform where the same happens by API. Kraken offers both a portal that returns executable quotes and a chat route where the trade desk confirms the asset, lot size and price.

What #bitcoin-otc is, and why it is not this

Search for bitcoin OTC and one of the first results is bitcoin-otc.com. It is a different thing.

The site describes itself as “an over-the-counter marketplace for trading with bitcoin” located in the “#bitcoin-otc channel on the Libera Chat IRC network.” It states that it is “merely an aggregator of outstanding supply and demand,” and that trades happen “directly between counterparties, without any participation or intermediation from #bitcoin-otc.” It maintains a reputation “web of trust” and warns that this “is not foolproof.”

Read those words as a list of what is absent: no firm on the other side, no onboarding, no binding quote, no settlement obligation, and no recourse beyond what the individual you found chooses to honor. Everything below is about desks, which are firms.

Desk, exchange order book and peer-to-peer marketplace

Three venues, three different answers to the same six questions.

OTC desk, exchange order book and peer-to-peer marketplace compared
Question Bitcoin OTC desk Exchange order book Peer-to-peer marketplace
Your counterparty The desk, as principal, or the venues it routes to as your agent Users you never see, with the exchange between you An individual found through the board
How the price forms A quote for the whole amount, valid for a short stated window By queue: your order consumes resting orders level by level By negotiation, person to person
Who sees the order You and the desk, until it hedges Everyone: depth is public and every fill prints Everyone reading the channel
Onboarding Identity, ownership, source of funds, before any quote The exchange's account verification None; a reputation score at most
Settlement Bilateral, on agreed terms, commonly within 24 hours Inside the exchange, against your balances However you agree, with no third party bound
If the other side fails You hold a contract with a firm, and its status matters The exchange's rules and its own solvency No firm is liable; the trust system is “not foolproof”

How a quote is built

A desk quoting a firm price for size is taking a position, so the number reflects what that position is worth to it at that moment. Cumberland states what goes in: “current index prices, market liquidity, volatility, and our overall position in the market.” That is four inputs, and one more the desk rarely spells out.

  • A reference price. An index or mid, not the last trade on a single venue.
  • Your size against available liquidity. The same amount is a different problem on a thin Sunday than on a busy Wednesday.
  • Volatility. The desk is exposed from the moment you accept until it hedges, and a wider market costs more to cross.
  • The desk's own position. A firm already long bitcoin quotes a buyer differently from one that is flat.
  • Your settlement terms. A pre-funded client and one trading on credit are different risks.

Where the desk's margin sits depends on its capacity. As principal it is inside the price: Kraken's OTC desk states that its quoted prices are “all-inclusive” with no service fee, and Cumberland says it charges no fees as a principal. As agent it is a separate charge: Coinbase's annual report for 2025 says Prime routes customer orders to third-party venues and charges a transaction fee. US securities rules draw the same line for broker-dealers, between a markup on a principal sale and a commission on an agency one (SEC, Investor.gov).

Some firms aggregate rather than quote from one book. In 2023 Bitstamp described its request-for-quote service as sourcing quotes from its multiple dealers for each trade, and Gemini describes its electronic crypto OTC orders as executed against price sources from several liquidity providers. Either way the quote window is short, often seconds: a price that stands for a minute is an option granted at the desk's expense, and desks do not give those away.

Who uses desks, and at what size

Desks describe their clients narrowly. Galaxy's annual report for 2025 lists “institutional allocators, asset managers, hedge funds, family offices, and high-net-worth individuals,” and a 2025 quarterly filing defines the individuals it serves as Eligible Contract Participants under the Commodity Exchange Act, knowledgeable employees and accredited investors. FalconX describes itself as a prime brokerage for “asset managers, hedge funds, family offices, venture funds, miners, protocols, banks, and other financial institutions.” B2C2 states that it “does not transact with or provide any service to any retail investor or consumer.”

What desks publish as a minimum

Most publish nothing. Treat the table as a record of what was on each page on 19 September 2026, not as a market rule.

Minimums and eligibility these firms publish
Firm What it publishes Where
Kraken US$50,000 equivalent minimum order, with case-by-case exceptions, in one place; US$100,000 in another. Eligibility subject to anti-money-laundering and identity requirements Support article, 10 December 2025; bitcoin OTC page
Gemini US$1,000 notional per order, on its electronic platform only, not a voice desk minimum Institutional page, September 2026
River Invites private-client investment of US$100,000 or more with a relationship manager Private client page, September 2026
Bitstamp A US$100,000 to US$1 million band, subject to change, not available to US or UK customers Blog post, 29 November 2023, so current terms are unverified
Cumberland, Galaxy, FalconX, B2C2, Wintermute No minimum published. Cumberland requires a counterparty to be approved; B2C2 serves no retail clients Firm pages and filings, September 2026
Each entry is a dated description of what the firm publishes about itself. It is not a ranking, a recommendation or an offer, and no relationship is implied. Minimums and terms are set only by the desk.

Settlement: the part that decides who carries whom

A quote is half the trade. The other half is who sends first, and what happens in the gap.

Pre-funding means your money or coins sit with the desk before you trade: the desk takes no credit risk on you, and you take it on the desk. Post-trade settlement reverses that. Cumberland states that “All trades with Cumberland are settled post-trade,” often in less than 24 hours, with API trades netted in a 24-hour roll-up. Kraken lets eligible clients trade now and settle later, within 24 hours. Gemini describes intraday delayed net settlement as a way to avoid “pre-funding requirements.”

Two practical points close the loop. Kraken states that the name on your bank account has to match the name on your trading account, and that its OTC desk “does not custody assets on behalf of trading counterparties” — execution and custody are separate decisions. And the dollar leg keeps bank hours: Fedwire treats all Saturdays and Sundays as holidays. The buying and selling pages, large bitcoin purchases and selling bitcoin OTC, work through each side.

Telling a desk from an impersonator

The most common fraud in this market is not a bad price. It is a firm that does not exist, or a real firm's name and website copied closely enough to pass a glance.

California's Department of Financial Protection and Innovation runs a Crypto Scam Tracker built from complaints it receives, and states that “Imposter websites are one of the most common reported scams” (accessed September 2026). Its entries include lookalike domains and schemes run through messaging groups. The FTC is blunter: “Only scammers demand payment in cryptocurrency,” they impersonate “established companies, government agencies, law enforcement,” and crypto payments “typically cannot be reversed.”

A joint CFTC and SEC investor alert on fraudulent crypto trading websites lists the red flags: guaranteed returns, unsolicited contact, high pressure and unregistered firms. The CFTC also publishes a RED List of foreign entities that appear to require CFTC registration while not being registered, noting that inclusion “does not mean that the CFTC or a court has concluded that a violation ... has occurred.” In the United Kingdom the FCA warns that “Most crypto-related activities aren't regulated in the UK,” so there is generally no access to the Financial Ombudsman Service, and separately warns about recovery room scams.

The FBI's Internet Crime Complaint Center has published repeatedly on the same pattern: fictitious law firms contacting crypto fraud victims and claiming government links (PSA I-062424-PSA, 24 June 2024, and PSA I-081325-PSA, 13 August 2025), and impersonation of IC3 itself, which “does not maintain a social media presence and does not investigate crimes or recover funds through Facebook, Telegram, or similar platforms” (PSA I-072026-PSA, 20 July 2026).

Six checks separate a desk from an impersonation, and they cost nothing.

  1. It onboards before it quotes

    A real desk asks for identity, ownership and source of funds first. A fake one wants to talk about price immediately.

  2. The domain and the entity match

    Check the exact domain against the firm's regulatory filings, not against a link sent to you. Lookalike spellings are the whole technique.

  3. It appears on a register

    Look the firm up on the FCA Register, or the CFTC RED List for US commodity activity, and read the entity names in its own footer.

  4. It contracts in writing

    Terms, confirmations and settlement instructions on the firm's paper, not a chat message.

  5. It settles in your own name

    Accounts and wallets in the client's name, never a third party, and never a “new” address sent at the last minute.

  6. You verify by voice

    Confirm every address and wire instruction on a number you already held. Treat any late change as fraudulent until you have.

Risk

What can go wrong in a bitcoin OTC trade

  • Counterparty risk. With a principal desk, the desk is the other side. Whoever delivers first is the other's creditor until the second leg lands, and a balance left with a desk afterwards is a claim, not a holding.
  • Settlement risk. Bitcoin sent to a wrong or substituted address cannot be recalled. Agree in writing who sends first, by when, and to which address and account.
  • Impersonation and recovery scams. Imposter websites and messaging-app approaches are the common pattern, and victims are then targeted again by “recovery” services. The CFTC calls those “a form of advance-fee fraud.”
  • Regulatory gaps. Much crypto activity sits outside the protections that apply to regulated investments, so the usual complaint and compensation routes may not be open.

The hub page, bitcoin OTC, sets out the same risks alongside onboarding, and how it works sets out the stages an introduction runs through.

Primary sources

OTC bitcoin trading: questions

What does OTC mean in bitcoin trading?

Over the counter means away from an exchange's central order book. You agree a single price for a set amount directly with one counterparty, usually a desk, and the two of you settle it between yourselves. Nothing prints to a public trade record as the order fills, and the terms are whatever the two parties agree rather than the venue's rules.

Is bitcoin-otc.com an OTC desk?

No. It describes itself as an over-the-counter marketplace in the #bitcoin-otc channel on the Libera Chat IRC network, and says it is merely an aggregator of outstanding supply and demand, with trades happening directly between counterparties without any participation from it. It runs a reputation web of trust and warns that this is not foolproof. No desk stands behind a trade there.

What is the minimum size for a bitcoin OTC trade?

There is no single threshold, and most institutional desks publish none. As of September 2026 Kraken's own pages give two different figures, US$50,000 in a support article and US$100,000 on its bitcoin page. Gemini publishes a US$1,000 notional minimum per order on its electronic platform only. Each desk decides whether it will quote.

How do you tell a real bitcoin OTC desk from a fake one?

A real desk onboards you before it quotes, contracts with you in writing, and settles to an account in your own name. Warning signs are an unsolicited approach on a messaging app, a lookalike domain, pressure to send first, and a request to pay a personal wallet. California's regulator reports that imposter websites are among the most common scams it records.
