How OTC actually works
The desk takes the other side of your trade onto their own book. You get an all-in price including their markup. Risk: counterparty until settlement. Used by Cumberland, B2C2, Wintermute.
The desk works your order across multiple venues using TWAP/VWAP or smart order routing. You pay an explicit commission (1-10 bps). Better for very large orders without information leakage.
Settlement same-day or next-day. Cash leg via SWIFT or via stablecoin (USDC dominant institutional). BTC leg via cold-storage withdrawal or pre-funded sub-account. Always lock counterparty risk to lowest practical window.

OTC operational checklist
Before your first trade
- Onboard with at least two desks to compete quotes
- Complete KYC + KYB early — most desks need 1-3 weeks for institutional onboarding
- Sign an ISDA-style master trading agreement; understand default and termination triggers
- Set up settlement instructions: bank for fiat leg, custody wallet for BTC leg (cold storage with appropriate transaction signing)
- For >$5M tickets: pre-arrange T+0 settlement via stablecoin (USDC) to remove banking friction
- Establish credit limits or pre-funding requirements
⚠️ Red flags on a desk
- No demonstrable proof of reserves or balance sheet
- Settlement via personal accounts or undisclosed third parties
- Spreads more than 5x typical for similar size (50+ bps on $1M BTC tickets)
- Insistence on holding your BTC for "convenience" before settlement
- No formal trading agreement or termination terms
- Single-key custody on the BTC leg (institutional desks use multisig)
FAQ
How is OTC pricing better than the exchange order book?
For trades above ~$500K, exchange order books in BTC have meaningful slippage. A $1M market buy on a typical Asian exchange can move price 10-30 bps. OTC desks quote inclusive of their inventory cost — for similarly sized trades you typically get 1-5 bps total cost from a tier-1 desk, materially better.
Do OTC desks report my trades to tax authorities?
Regulated desks (OSL, HashKey, Sygnum, etc.) report under their license obligations — typically counterparty disclosure on settlement. Unregulated offshore desks may not. As of 2027 with OECD CARF rollout, regulated Asian desks will automatically share annual disposal data with your tax residence country.
What's the smallest amount that makes OTC worthwhile?
Practically, $100K and up. Below that, the operational overhead (onboarding, banking, settlement coordination) exceeds the spread savings. Most retail users are better served by regulated exchange large-order desks (Coinhako VIP, HashKey Exchange institutional flow) until they cross ~$250K per trade.
Can I do OTC anonymously?
Not at credible desks. All licensed desks require institutional KYC + source-of-funds documentation. P2P (Bisq, RoboSats, Hodl Hodl) is the privacy alternative but has size limits (typically <$50K per trade) and counterparty diligence overhead.
How does block trading on Asian exchanges differ from OTC?
Block trading (large-order RFQ on a regulated exchange like HashKey, Coinhako, or Sygnum) routes through the exchange's order management but with negotiated pricing. Closer to an exchange-mediated OTC than a true off-exchange trade. Settlement is via exchange custody. Useful for users who want exchange-level compliance with OTC-style pricing.
