What Is OTC Trading?
๐ 7 min read
Quick Answer
When you try to buy or sell a large amount of Bitcoin on a normal exchange, your own order moves the price against you. OTC (over-the-counter) trading solves this by matching big trades directly between two parties, off the public order book. It is how whales, businesses and serious investors move size without slippage, and the basics are worth understanding.
๐ A simple way to see it
Buying a lot of Bitcoin on an exchange is like trying to buy every sandwich in a small shop at once, you clear the cheap ones and end up paying more for each as you go (slippage). An OTC trade is like ringing a wholesaler and agreeing one price for the whole pallet, no shelf-clearing, no price spike.
What OTC trading is
OTC means trading directly with one counterparty at an agreed price, instead of through a public exchange order book. It is used for large trades, where putting the order on an exchange would move the market. The two sides agree an amount and a price (often a small premium or discount to spot) and settle between themselves.
Why big trades need it: slippage
An exchange order book has limited liquidity at each price. A large market order eats through it, filling at progressively worse prices, that gap is slippage, and on a big order it can cost a lot. OTC avoids this by settling the whole amount at one negotiated price, so a $200,000 trade does not visibly spike the market or leak your intentions.
How OTC desks work
Traditional OTC desks (run by exchanges or brokers) take your order, source the other side from their network, and settle, usually with custody and KYC, aimed at institutions and high-net-worth clients. They offer deep liquidity and a smooth process, but you trust the desk with your funds and identity.
Custodial vs non-custodial OTC
Custodial desks hold funds and require KYC. Non-custodial, peer-to-peer OTC instead simply matches a compatible buyer and seller and lets them settle directly (for example via multisig escrow or Lightning), so no platform ever holds the coins. This trades some convenience for self-custody, privacy and no counterparty-custody risk, the same trade-off as self-custody everywhere in Bitcoin. Our own anonymous, non-custodial OTC matching desk follows this model.
The risks to know
OTC removes slippage but adds counterparty risk: you must trust (or escrow against) the person on the other side. Use escrow for large trades, verify your counterparty, agree clear terms in writing, never send first without protection, and be aware that large trades and OTC services can carry tax and regulatory obligations where you live.
๐ Key takeaway
OTC (over-the-counter) trading matches large Bitcoin trades directly between two parties at one agreed price, avoiding the slippage a big order causes on an exchange. Traditional desks are custodial and KYC-based; non-custodial peer-to-peer OTC just matches buyer and seller and lets them settle themselves (e.g. multisig escrow), keeping self-custody and privacy. The main risk is counterparty trust, so use escrow for size.
Why this matters for you
Across Asia, growing numbers of businesses, miners and high-net-worth investors need to move large amounts of Bitcoin without moving the market or, sometimes, without the surveillance of a custodial desk. Understanding OTC, and non-custodial OTC in particular, gives the region's larger traders a way to trade size with better prices, more privacy and full control of their coins.
Frequently asked questions
What is OTC trading in crypto?โผ

What is non-custodial OTC trading?โผ
A model where a platform only matches a compatible buyer and seller and lets them settle directly (for example via multisig escrow or Lightning), without ever holding the coins or requiring KYC. It keeps self-custody and privacy, at the cost of the convenience a full custodial desk provides.
