Over-the-counter (OTC) trading lets you sell Bitcoin directly to a buyer off-exchange, with negotiated terms. It’s the preferred route for high-volume sellers who want to avoid slippage, protect privacy, or settle in fiat or stablecoins.
If you’re liquidating part of a treasury, rotating funds, or managing institutional flows, OTC offers tighter spreads and custom execution. This guide breaks down how to sell Bitcoin OTC in 2025.
Step-by-step, we’ll cover how to pick a desk, request quotes, negotiate fees, complete the settlement, and avoid common pitfalls.
Step-by-Step Process to Sell Bitcoin OTC
Selling Bitcoin OTC isn’t complex, but it does require precision, especially at high volumes.
Here’s how the process works from start to finish:
1. Choose a Regulated Desk or Broker
Decide whether you want a principal desk (they buy from you directly) or an agency broker (they find buyers on your behalf).
Look for firms regulated in your jurisdiction with a strong track record in crypto settlement.
2. Complete KYC/AML and Wallet Whitelisting
You’ll need to verify your identity and source of funds.
Most desks also require pre-approved wallet addresses for sending BTC.
This step is mandatory and non-negotiable for compliant trades.
3. Request a Firm Quote (RFQ)
Submit a request for quote (RFQ) for your BTC size.
The desk will return a firm bid, typically valid for a short time (e.g., 30 seconds to 2 minutes). In volatile markets, timing matters.
4. Lock the Price and Transfer BTC
Once you accept the quote, send BTC to the desk’s designated wallet or escrow service.
The transaction is monitored on-chain, and the quote is locked once the transfer is confirmed.
5. Receive Fiat or Stablecoin Settlement
After confirmation, you’ll receive fiat (e.g., USD, EUR) via wire or stablecoins (e.g., USDT, USDC) to your whitelisted wallet or bank account.
Settlement times vary by desk and currency rails.
6. Get Post-Trade Reporting and Custody Confirmation
Some desks provide trade confirmations, execution reports, and compliance logs.
If you’re using third-party custody, assets may be handed off to your custodian as part of the workflow.
Where Can I Trade OTC?
OTC Bitcoin trading isn’t limited to one type of venue.
You can sell through institutional desks, peer-matching platforms, or private client services, depending on your needs.
Tier-1 Broker Desks
These are regulated exchanges or crypto institutions with dedicated OTC arms.
They offer deep liquidity, compliance support, and seamless fiat settlement.
Examples: Kraken OTC, Coinbase Institutional, Binance OTC, OSL.
P2P and Market-Maker Platforms
These platforms connect you directly with buyers or market makers, often using an automated matching engine.
Some offer escrow services for added protection.
Examples: OKX OTC, Bitstamp OTC Portal.
Private-Client Desks and Family Office Services
For ultra-high-net-worth sellers, bespoke OTC services provide discretion, tailored settlement, and treasury solutions.
These desks typically have higher minimums and concierge-level execution.
Examples: boutique desks operated by crypto-native firms or wealth advisors.
Choosing a Reliable OTC Partner
Not all OTC desks operate the same.
To protect your funds and optimize execution, use this checklist when evaluating potential partners:
| Criteria | What to Look For |
| Licensing & Jurisdiction | Registered with a financial authority (e.g., FinCEN, FCA, MAS). Avoid unregulated desks. |
| Minimum Trade Size | Some desks start at 5 BTC; others require ≥25 BTC. Know the threshold upfront. |
| Liquidity Sources | Ask if they internalize trades, access multiple buyers, or rely on a single counterparty. |
| Settlement Options | Confirm fiat currencies, stablecoins, and rails supported (SWIFT, SEPA, ACH, USDC). |
| Custody Model | Does the desk hold funds in escrow, work with custodians, or require pre-funding? |
| Execution Model | Principal desks offer firm bids; agency desks shop your trade around. Understand the model. |
| Reputation & Transparency | Look for trade reporting, past audits, or referrals from trusted institutions. |
If a desk can’t clearly explain how they price trades, handle custody, or comply with regulations, move on.
Pricing Mechanics & How to Negotiate the Best Fill
OTC pricing isn’t always transparent.
Here’s how it works and how to optimize your execution:
Quote Spreads vs. Commission Fees
Some desks quote an all-in price (the spread), while others charge a fee on top.
Always ask for the net proceeds you’ll receive after fees.
For large trades, even a 0.25% difference can be significant.
Use TWAP/VWAP for Very Large Trades
For blocks above 50 BTC, some desks offer execution strategies like:
- TWAP (Time-Weighted Average Price): Selling gradually over time to reduce market impact.
- VWAP (Volume-Weighted Average Price): Aligning trades with real market volumes for better pricing.
These strategies can help match or beat quoted bids, especially when dealing with thin liquidity windows.
Consider Hedging During Settlement
If there’s a delay between locking your price and receiving fiat, some desks offer hedging via CME Bitcoin futures.
This protects you from adverse BTC price swings before settlement clears.
Tip: Get Competing Quotes
Even if you’ve used one desk before, don’t rely solely on them.
Request RFQs from 2–3 desks within minutes of each other.
Desks know they’re being compared—and often improve pricing in response.
Advanced Selling Scenarios
OTC isn’t just for simple sell-offs.
It also supports nuanced strategies that aren’t feasible on public exchanges.
Partial Liquidation of Mining Treasury
Miners often hold large balances across wallets.
OTC desks can help liquidate in tranches without disrupting market price.
Some desks even offer structured payouts aligned with mining revenue cycles.
Cross-Pair Swaps (BTC → USDT → USD)
If you’re operating across jurisdictions or need faster liquidity, desks can structure trades through stablecoins (e.g., USDT or USDC), then convert to fiat.
This helps bypass banking delays while keeping exposure limited.
Stablecoin Settlement to Avoid Banking Lag
Want to avoid waiting 2–3 days for wire transfers?
Request settlement in regulated stablecoins.
Many desks now offer instant USDC payouts to your wallet or custodial partner, especially for trades under $10M.
Custom Settlement Terms
Some desks allow delayed delivery, escrow holdbacks, or multi-leg settlements for complex treasury or fund operations.
If your transaction involves counterparties, taxes, or compliance steps, ask about custom structuring.
Case Study: Disposing of 100 BTC via OTC vs. Exchange
Let’s compare how a 100 BTC sale would play out across two common routes: an OTC desk and a public exchange.
| Factor | OTC Desk | Exchange (e.g., Binance/OKX) |
| Execution Price | Custom quote, locked at market or negotiated | Market orders spread across order book |
| Slippage | ~0.1–0.25% typical | 0.75%+ common for 100 BTC (unless split manually) |
| Fees | Flat rate or baked into spread (e.g., 0.2–0.5%) | Trading fee + withdrawal fee (~0.1–0.2%) |
| Settlement | Direct fiat or USDC to bank/wallet | Requires conversion and withdrawal delay |
| Time to Cash | 1–6 hours (depending on fiat rails) | 1–3 days (incl. fiat withdrawal time) |
| Privacy & Reporting | Off-book, visible only to counterparties | Fully visible on-chain and in exchange logs |
While OTC desks may seem more expensive at first glance, the total cost of execution (including slippage, fees, and delays) is often lower, especially for trades over 50 BTC.
This is why funds, miners, and treasuries choose OTC for large exits—it’s faster, cleaner, and ultimately more cost-efficient.
