Over-the-counter (OTC) cryptocurrency trading has become a preferred method for institutional investors, high-net-worth individuals, and large traders seeking to execute substantial transactions without impacting market prices. Unlike traditional exchange-based trading, OTC platforms facilitate direct trades between buyers and sellers, offering enhanced privacy, reduced slippage, and personalized service. As the digital asset market matures, selecting the right OTC exchange is crucial for efficiency, security, and cost-effectiveness.
This guide explores the 7 best crypto OTC exchanges in 2025, highlighting their unique features, minimum order sizes, fee structures, and service offerings. Whether you're managing institutional capital or executing large personal trades, understanding these platforms will help you make informed decisions.
How Do Crypto OTC Exchanges Work?
Crypto OTC desks operate by connecting buyers and sellers directly, often through dedicated brokers or automated systems. These platforms typically enforce minimum trade thresholds—usually starting from $50,000—making them ideal for large-volume transactions. Most require user verification (KYC) and assign personal account managers to streamline communication.
OTC desks generate revenue through spreads or commissions, which can range from 0.1% to 1% of the transaction value. Some platforms offer zero-fee trading but compensate via slightly wider spreads. Many top-tier OTC services are integrated into larger exchanges, giving users access to deep liquidity pools and advanced tools like intelligent order routing and real-time pricing.

Top 7 Crypto OTC Exchanges in 2025
Binance OTC Desk
Binance remains a leader in the crypto space, and its OTC desk caters specifically to institutional clients and high-volume traders. The platform supports over 350 cryptocurrencies and numerous fiat pairings, including USD, EUR, and GBP.
One of Binance’s strongest advantages is its massive liquidity pool—even for low-market-cap tokens—ensuring fast execution with minimal slippage. The OTC desk enables both crypto-to-crypto and crypto-to-fiat trades, with settlements confirmed within minutes.
While Binance doesn’t charge explicit trading fees on OTC transactions, it enforces a steep minimum order size of $200,000, limiting accessibility for smaller traders. Despite this, the intuitive interface and built-in educational pop-ups make it beginner-friendly for those new to large-scale trading.
Coinbase Prime
Coinbase Prime is more than just an OTC desk—it's a comprehensive suite designed for institutions. Integrated within the broader Coinbase ecosystem, Prime offers OTC block trading with enhanced execution speed and price anonymity.
A key differentiator is its intelligent order routing system, which aggregates liquidity from multiple sources across the Bitcoin and broader crypto markets. This ensures competitive pricing beyond Coinbase’s internal exchange rates.
Additional features include margin trading, detailed post-trade reporting, NFT custody, and participation in staking and governance for supported tokens. These value-added services make Coinbase Prime one of the most feature-rich OTC platforms available.

Kraken OTC
Kraken’s OTC desk stands out for its zero-commission model, allowing traders to execute large orders without direct fees. Based in the U.S. and available globally, Kraken supports over 200 cryptocurrencies and seven fiat currencies.
Its Automated Request for Quote (AutoRFQ) system enables instant pricing on large trades by automatically querying multiple liquidity providers. This eliminates manual quote requests and accelerates deal execution.
The minimum trade size is $100,000, which is competitive compared to other major platforms. Kraken also emphasizes security and regulatory compliance, making it a trusted choice for professional traders concerned about asset protection.
KuCoin OTC
KuCoin’s OTC service operates via a peer-to-peer (P2P) model, allowing users to trade directly with counterparties using fiat or crypto. Transactions are secured through an escrow system: KuCoin holds the seller’s crypto until the buyer completes the fiat transfer.
This model helps avoid market impact and provides flexibility in payment methods. The platform supports major currencies like USD, CNY, USDT, ETH, and BTC.
Notably, KuCoin integrates a leading decentralized oracle network to provide real-time, tamper-proof exchange rates between fiat and digital assets. This enhances transparency and fairness in pricing.
Best of all, KuCoin charges no fees for OTC trades, making it an attractive option despite slightly lower liquidity than top-tier competitors.
Bitfinex OTC
Bitfinex offers a streamlined user-to-user OTC trading experience. To initiate a trade, users only need their counterparty’s nickname—once the request is accepted, the transaction proceeds instantly.
With a remarkably low minimum trade size of $50, Bitfinex is one of the most accessible OTC platforms. However, it enforces a price spread cap of ±10% from the current market rate to prevent manipulation.
Bitfinex charges a minimal 0.1% commission on both sides of the trade. Security features include two-factor authentication (2FA), withdrawal safeguards, and OpenPGP email encryption—making it a solid choice for privacy-conscious traders.
Bitstamp OTC
Established in 2011, Bitstamp has evolved into a reliable player in the OTC space. Its Automatic Request-for-Quote (RFQ) system allows users to submit trade details such as volume and preferred price range.
Market makers then respond with bids, enabling quick execution without slippage. Bitstamp connects traders with multiple liquidity providers, ensuring deep order books and stable pricing.
Trade sizes range from $50,000 to $500,000 per transaction, striking a balance between accessibility and institutional focus. Supported pairs include BTC/USD, BTC/EUR, and LTC/USD.
Although Bitstamp acts as a middleman to preserve anonymity, it complies with KYC regulations and requires identity verification.
Huobi OTC Desk
Huobi’s dedicated OTC desk—Huobi Desk—serves institutional clients with a focus on capital efficiency and competitive pricing. It functions as a P2P marketplace where Huobi acts as an intermediary to reduce slippage risk.
Traders can lock in prices and settle funds to bank accounts, external wallets, or their Huobi account. Currency options include major stablecoins (USDT, USDC) and fiat currencies like USD, GBP, and HKD.
No fees are charged on OTC transactions. Huobi also adheres to strict regulatory standards, enforcing thorough KYC checks—including income verification—for added security.
