Bitcoin has once again surged past key price thresholds, reigniting global interest in cryptocurrency trading. As more users enter the space, understanding the fundamental ways to buy and sell Bitcoin—on-chain (exchange-based) and off-chain (peer-to-peer or over-the-counter)—becomes essential. While both methods serve the same purpose, they differ significantly in execution, risk, accessibility, and user experience.
This article explores the distinctions between on-exchange and off-exchange Bitcoin trading, dives into common off-exchange trading models, and highlights real-world usage patterns based on market data. Whether you're a beginner or an experienced trader, gaining clarity on these mechanisms can help you make safer, more informed decisions.
What Is On-Exchange vs. Off-Exchange Bitcoin Trading?
At its core, Bitcoin trading falls into two primary categories: on-exchange (or "on-chain") and off-exchange (commonly known as OTC or peer-to-peer).

On-Exchange Trading
On-exchange trading occurs on centralized digital asset platforms where buyers and sellers place orders that are matched automatically by the system. These exchanges act as intermediaries, providing liquidity, price discovery, and security measures such as identity verification (KYC) and cold storage for assets.
Examples include major platforms like OKX, Binance, and Kraken. Transactions here are fast, transparent, and regulated to varying degrees depending on jurisdiction.
Off-Exchange (OTC / P2P) Trading
Off-exchange trading refers to direct transactions between two parties without relying on a formal exchange infrastructure. This model emerged before centralized exchanges existed and remains popular due to its flexibility and privacy.
There are three main forms of off-exchange Bitcoin trading:
- Online P2P Marketplaces
- Online B2C Platforms
- Offline Face-to-Face Transactions
We’ll examine each in detail below.
The Three Main Forms of Off-Exchange Bitcoin Trading
According to monitoring by the National Internet Finance Safety Technology Expert Committee, off-exchange Bitcoin activity primarily takes place through these three channels.
1. Online Peer-to-Peer (P2P) Trading
Platforms like LocalBitcoins and CoinCola function as digital marketplaces where individuals post buy or sell offers. Buyers browse listings and initiate trades directly with sellers—much like shopping on e-commerce sites.
The platform typically holds the seller’s Bitcoin in escrow until the buyer confirms payment via their chosen method (e.g., bank transfer, Alipay). Once confirmed, the Bitcoin is released.
This model offers high flexibility but requires trust or strong dispute resolution systems to prevent fraud.
2. Online Business-to-Customer (B2C) Trading
In B2C models, users trade directly with a business entity rather than another individual. The platform sets fixed prices and uses its own inventory—or partner-supplied reserves—to fulfill orders.
After a user sends fiat currency (like CNY), the system automatically releases Bitcoin. This reduces counterparty risk since the platform acts as a guaranteed seller or buyer.
While less flexible in pricing, B2C services often provide faster execution and better customer support.
3. Offline In-Person Trading
Some users still prefer face-to-face Bitcoin transactions. These occur either through private arrangements arranged via messaging apps (like WeChat or QQ groups) or at physical meetups.
Although this method maximizes privacy, it also carries higher risks—such as theft or misrepresentation—due to lack of oversight and escrow protection.
Shifts in the Global P2P Landscape After Regulatory Changes
Regulatory developments have significantly reshaped the off-exchange ecosystem. In September 2017, Chinese authorities implemented strict policies targeting cryptocurrency trading platforms. As a result, domestic P2P services like Bikand and BitHui gradually ceased operations.
Today, most Chinese-speaking users access international platforms for BTC-CNY trading. The four most widely used overseas platforms include:
- LocalBitcoins
- Paxful
- CoinCola
- BitcoinWorld
These platforms operate globally and support multi-language interfaces, enabling seamless cross-border transactions.
Preferred Payment Methods in BTC-CNY P2P Markets
Data from Paxful reveals that 96.3% of BTC-CNY transactions completed on its platform used Alipay for RMB transfers. Only 2.7% used WeChat Pay, while iTunes gift cards accounted for 0.56%.
Similarly, analysis of sell-side advertisements shows:
- On LocalBitcoins, 57% of sellers accept Alipay; 28% prefer bank transfers.
- On CoinCola, 85% of sellers list Alipay as their preferred method; bank transfers come second at 12%.
This dominance reflects Alipay’s widespread adoption, ease of use, and instant settlement features—making it ideal for time-sensitive crypto trades.

Frequently Asked Questions (FAQ)
Q: What is the difference between on-exchange and off-exchange Bitcoin trading?
A: On-exchange trading happens on centralized platforms where orders are matched automatically. Off-exchange trading involves direct transactions between parties via P2P platforms or in person, offering more privacy but potentially higher risk.
Q: Is P2P Bitcoin trading safe?
A: It can be safe if conducted through reputable platforms with escrow protection and user verification. However, always verify counterparty reputation and avoid releasing funds before confirming receipt of crypto.
Q: Why do most Chinese users prefer Alipay for Bitcoin trades?
A: Alipay offers instant transfers, wide accessibility, and integration with mobile devices—making it fast and convenient for time-sensitive P2P transactions.
Q: Are there risks involved in offline Bitcoin trading?
A: Yes. Offline trades lack third-party oversight, increasing exposure to scams or physical threats. Always meet in public places if conducting face-to-face deals and use secure wallets.
Q: Can I buy Bitcoin without ID verification?
A: Some P2P platforms allow limited anonymous trading, but most regulated services require KYC for larger volumes. Fully anonymous transactions may carry higher risks.
Q: How has regulation affected Bitcoin P2P markets in China?
A: Domestic platforms shut down after 2017 regulations. Users now rely on international services based abroad, continuing BTC-CNY trading under new operational frameworks.
Final Thoughts: Choosing the Right Trading Method Matters
As Bitcoin continues to gain momentum in 2025 and beyond, traders must understand the tools available to them. While on-exchange platforms offer speed and security, off-exchange options provide flexibility—especially for those dealing in local currencies like CNY.
Understanding the nuances of P2P marketplaces, preferred payment rails like Alipay, and evolving global platform availability empowers users to navigate the crypto landscape confidently.
