A $100 million Bitcoin purchase on a public exchange would move the market significantly before the order filled. Every order book participant would see the large buy coming, front-run it, and the final average execution price could be 1–3% worse than the starting price. OTC trading solves this problem. An institution calls their OTC desk at Cumberland or Coinbase Prime, asks for a quote for 1,000 BTC, receives a single off-book price within seconds, and executes the entire trade bilaterally. The order never touches the public order book. No price impact. No front-running. This is why institutional investors, miners, and large whales overwhelmingly use OTC for significant positions — and why a large fraction of crypto’s daily volume never appears in standard exchange volume statistics.
How OTC Trading Works: The RFQ Process
The following sections cover this in detail.
Request for Quote (RFQ)
- Client contacts desk: Phone, chat, or electronic API → “I want to buy 500 BTC”
- Desk quotes: OTC desk quotes a single all-in price: “I’ll sell you 500 BTC at $68,500 each”
- Client accepts/rejects: Typically within 30–60 seconds; price is firm for that window
- Trade executes: Bilateral agreement; both parties commit to the trade at the agreed price
- Settlement: Typically T+0 or T+1; either exchange-based settlement (OTC desk transfers BTC to client wallet; client wires USD to desk) or prime brokerage settlement
Why OTC Desks Can Offer Prices
OTC desks are professional market makers:
- They maintain large crypto and fiat inventories
- They hedge their net exposure on exchanges (immediately after quoting client)
- They earn the bid-ask spread between the quote price and their hedging cost
- Larger trades: Wider spread (more risk during the hedge execution window); smaller trades: tighter spread
Example:
- Cumberland quotes you 500 BTC at $68,500 (bid on BTC is $68,300 on Binance)
- You accept; Cumberland immediately begins selling futures or buying spot hedges on exchange
- Cumberland’s P&L: $200 spread × 500 BTC = $100,000 (before their hedging costs)
Who Uses Crypto OTC
The following sections cover this in detail.
1. Miners
Why: Miners receive block rewards daily (~450 BTC/day for all Bitcoin miners combined). Selling 50+ BTC at once on retail exchanges would create visible sell pressure. OTC desks buy miner flow in bulk, providing predictable liquidity.
Major miner OTC relationships: Marathon Digital, Riot Platforms, and other public miners use OTC desks for production sales.
2. Institutional Investors
Why: Pension funds, hedge funds, family offices allocating millions+ need to fill positions without moving market.
- Buy-side: Long-term allocators accumulating BTC/ETH positions over time
- Sell-side: Institutional traders exiting positions as part of portfolio rebalancing
3. Crypto Funds and VCs
Why: When VCs receive token allocations at token launches (often at cliff+vest schedules), they need to liquidate without crashing the market. OTC desks provide the exit route.
Typical structure:
- VC fund holds 1M tokens from an early investment
- Instead of dumping on the open market: VC negotiates a “structured OTC sale” with an OTC desk
- OTC desk buys at a discount (5–10% below market) in exchange for immediate liquidity
- OTC desk distributes the tokens over weeks via exchange algo trading
4. Exchanges and Protocol Treasuries
Why: Exchange operational risks, treasury management, stablecoin conversion at scale.
- Early Ethereum Foundation sold ETH for operational expenses via OTC
- Various crypto companies convert treasury reserves OTC
5. Global Ultra-High-Net-Worth Individuals (UHNW)
Why: Privacy. Large trades on public exchanges leave visible order book footprints. OTC is private.

Block Trading vs. Physical OTC
The following sections cover this in detail.
Physical OTC (Classic Model)
- Settlement: Crypto → client; USD/stablecoin → desk
- Risk: Counterparty delivery failure during settlement window
Prime Brokerage OTC
- Trade settles within the prime broker’s internal books
- No crypto delivery until client withdraws
- Risk: Exchange/prime counterparty; regulatory
Electronic OTC (Algorithmic)
- Not truly “off-book” but manages execution timing to minimize impact
- TWAP (Time-Weighted Average Price): Breaks large order into small equal pieces executed over time
- VWAP (Volume-Weighted Average Price): Executes proportional to market volume at each moment
Settlement and Post-Trade
The following sections cover this in detail.
T+0 Settlement (Same Day)
Most crypto OTC desks offer same-day settlement because crypto transactions settle in seconds:
- Customer wires USD to desk’s bank account
- Desk transfers BTC to customer’s wallet (after bank wire clears; often faster with stablecoins)
- Stablecoin settlement: Customer sends USDT → desk sends BTC near-instantly
Novation Risk (Post-FTX Concern)
After FTX’s collapse (November 2022), institutional clients became acutely aware of novation risk: If an OTC desk goes bankrupt during settlement, the client may have sent fiat but not received crypto (or vice versa). Best practices post-FTX:
- Collect crypto before wiring fiat (or use simultaneous atomic swaps where possible)
- Use regulated counterparties with segregated customer assets
- Monitor counterparty credit risk of OTC desks
OTC Pricing and Premium/Discount
The following sections cover this in detail.
When OTC Trades at Premium
Large buyers (institutions accumulating) may accept an OTC premium:
- Desk charges 0.1–0.5% above market for the certainty and speed of execution
- Premium reflects information value (desk takes risk that price moves before hedging)
When OTC Trades at Discount
Large sellers (mining companies, VCs wanting to exit) often accept a discount:
- Desk pays 0.5–2% below market price for the inventory
- Discount reflects risk the desk takes while distributing supply over time
Off-Market Trading: Structured Blocks
Pre-arranged “block trades” between parties who find each other privately (not via an OTC desk):
- Two institutions negotiate directly: “I’ll buy 1,000 BTC from you at $68,200”
- Execute on exchange or OTC at pre-agreed price
- Common in crypto futures markets (CME Bitcoin futures have formal block trade rules)
