The journey into the world of cryptocurrency begins with one critical step: fiat on-ramping. A seamless, secure, and efficient fiat trading experience sets the foundation for user confidence and long-term engagement. Leading exchanges recognize this and offer multiple fiat transaction models—such as instant buy, peer-to-peer (P2P) trading, and over-the-counter (OTC) services—to cater to diverse user needs.

Instant Buy: The Gateway for Beginners
For new users or those handling smaller transaction volumes, instant buy features provide a frictionless entry point. With a single click, users can purchase major cryptocurrencies like Bitcoin or Ethereum using local currency. However, accessibility varies across platforms.
For example, OKX allows users to start trading with as little as 10 RMB, making it highly accessible for beginners and low-budget investors. In contrast, competitors like Huobi require a minimum of 100 RMB, creating a higher barrier to entry. Notably, Binance does not offer an instant buy feature at all, which may deter novice users seeking simplicity and speed.
This highlights a key differentiator: inclusivity. By lowering minimum thresholds, exchanges empower more individuals to participate in the digital asset economy from day one.
P2P (C2C) Trading: Bridging Trust and Flexibility
Once users move beyond small transactions, peer-to-peer (P2P) trading becomes essential. Also known as C2C (customer-to-customer), this model connects buyers and sellers directly, offering greater flexibility in payment methods and pricing.
While most major exchanges support P2P trading—under names like “Self-Select Trade” (Huobi) or “Buy/Sell” (Binance)—the user experience differs significantly based on security protocols and identity verification systems.
Here, KYC (Know Your Customer) plays a pivotal role. OKX implements a three-tier KYC system:
- Basic Verification
- Advanced Verification
- Video Verification
Higher verification levels unlock increased withdrawal and trading limits, enhancing both security and scalability for serious traders. In comparison, Huobi offers only basic identity checks, while Binance supports two tiers—basic and advanced—but lacks the depth of OKX’s video-authenticated layer.
Robust KYC isn’t just about compliance—it protects users. Weak verification processes can allow illicit funds to enter the ecosystem, potentially leading to bank account freezes for innocent participants. Recovery is often difficult, sometimes impossible. A strong KYC framework ensures trust within the P2P marketplace, safeguarding all users.
OTC Trading: Efficiency Meets High-Volume Needs
For institutional players or individuals moving large sums, OTC (over-the-counter) trading is indispensable. These high-value transactions require minimal market impact and maximum privacy.
OKX’s OTC service functions as an upgraded version of P2P, with higher limits and stricter counterparty requirements. Huobi follows a similar structure but relies solely on basic KYC, posing potential risks. Binance takes a different approach: users input their desired trade size and receive personalized quotes. If unsatisfactory, they must re-initiate the process—an inefficient, time-consuming loop akin to blind date matchmaking.
In contrast, OKX and Huobi operate more like organized matchmaking events where multiple parties are visible simultaneously. But now, OKX has taken this a step further.
Game-Changer: Order Book Mode for P2P and OTC
In a groundbreaking move, OKX has introduced order book functionality to its P2P and OTC trading interfaces—a first in the industry. Traditionally reserved for spot and futures markets, the order book model brings unprecedented transparency and efficiency to fiat trading.
How does it work?
Buyers and sellers place orders ranked by price and time priority:
- Higher buy prices appear at the top of the bid side
- Lower sell prices rise to the top of the ask side
Each side displays up to 100 active orders, creating a dynamic, real-time marketplace.
This transforms what was once a manual search process into a structured, data-rich environment. Users no longer need to scroll endlessly through individual offers. Instead, they can instantly compare:
- Price competitiveness
- Transaction limits
- Completion rates
- Seller reliability
It’s like upgrading from random blind dates to a structured “Choose Your Partner” event with 100 candidates on each side—efficient, transparent, and highly effective.

Why This Matters: User-Centric Innovation
The introduction of the order book model reflects OKX’s commitment to user experience optimization. It bridges gaps across user segments:
- Small investors benefit from low minimums (10 RMB)
- Mid-tier traders enjoy secure P2P matching
- Institutions leverage scalable OTC solutions
Combined with tiered KYC and intuitive interface design, OKX delivers a comprehensive fiat gateway ecosystem.
Social media reactions confirm this shift. One user commented: “Now OKX covers everything—small amounts via instant buy, mid-range via P2P, large via OTC. It’s complete and thoughtful.” This holistic approach sets a new benchmark in the industry.
Compared to competitors:
- Huobi matches in product range but lags in KYC strength
- Binance improves on Huobi with two-tier verification but still trails OKX’s three-level system and lacks instant buy
With the addition of the order book model, OKX extends its lead—not just in features, but in execution.

Frequently Asked Questions
Q: What is the advantage of an order book in P2P trading?
A: It introduces real-time price discovery, transparency, and faster decision-making by organizing all available offers in a structured format—eliminating manual browsing.
Q: How does tiered KYC improve security?
A: Multi-level verification reduces fraud risk by validating user identities more thoroughly. Higher tiers require additional documentation and even live video checks, deterring bad actors.
Q: Can retail users benefit from OTC-style features?
A: Yes. While OTC traditionally serves large traders, the order book model benefits all users by improving price visibility and execution speed—even for smaller trades.
Q: Is the order book available for all currencies?
A: Initially rolled out for major fiat pairs like CNY and USD, with plans to expand based on demand and regulatory compliance.
Q: Does this reduce slippage in large trades?
A: While slippage is less relevant in fixed-price P2P trades, the order book helps users find optimal prices quickly, minimizing opportunity cost during volatile periods.
Q: How does this compare to traditional exchange order books?
A: Similar in structure but adapted for fiat settlement. Instead of automated matching engines, these orders represent real sellers/buyers with defined payment methods and terms.
