Bitcoin, the world’s first and most widely recognized cryptocurrency, continues to dominate the digital asset landscape. As of 2025, one Bitcoin is valued at approximately 422,400 RMB, making it a top choice for investors seeking exposure to decentralized finance. However, entering the crypto market requires more than just capital—it demands access to a secure, reliable, and user-friendly trading platform. This guide explores where and how to buy and sell Bitcoin safely, with a focus on trusted methods and best practices.
Understanding Bitcoin Trading Platforms
Cryptocurrency exchanges serve as the primary gateway for buying and selling Bitcoin. These platforms facilitate transactions between buyers and sellers using various methods. The key is selecting a reputable exchange that offers strong security, low fees, and intuitive tools—especially for beginners.
One of the leading platforms in the global market is OKX, ranked among the top cryptocurrency exchanges worldwide. It supports over 100 digital assets, including Bitcoin (BTC), Ethereum (ETH), and USDT, and provides advanced trading features such as spot, futures, and margin trading—all accessible via web and mobile apps.

How to Buy Bitcoin: Two Main Methods
There are two primary ways to purchase Bitcoin on most exchanges: fiat-to-crypto and crypto-to-crypto trading. Each has its advantages depending on your location, preferred payment method, and risk tolerance.
1. Fiat-to-Crypto Trading (RMB or USD Direct Purchase)
Fiat trading allows users to buy Bitcoin directly using government-issued currencies like Chinese yuan (RMB) or U.S. dollars. Most major exchanges offer a peer-to-peer (P2P) marketplace, where individual sellers list their Bitcoin for sale in exchange for local currency.
Here’s how it works:
- You select a seller with high ratings and sufficient transaction volume.
- Funds are held in escrow by the exchange until both parties confirm the transaction.
- After payment is made (via bank transfer, Alipay, WeChat Pay, etc.), the seller releases the Bitcoin.
This method is ideal for beginners who want to enter the market quickly without owning other cryptocurrencies first.
2. Crypto-to-Crypto Trading (Using USDT)
Most experienced traders prefer using USDT (Tether), a stablecoin pegged 1:1 to the U.S. dollar, as an intermediary currency. Instead of buying Bitcoin directly with RMB, users first convert cash into USDT through P2P channels, then trade USDT for BTC on the spot market.
Why use USDT?
- Price stability: Unlike volatile cryptocurrencies, USDT maintains a stable value.
- Wider availability: Many altcoins don't support direct fiat purchases but can be traded against USDT.
- Faster transactions: Once you hold USDT, swapping between digital assets becomes instant and efficient.
This two-step process—cash → USDT → BTC—is now the standard in the crypto community due to its flexibility and reduced counterparty risk.
Choosing the Right Bitcoin Trading App
With so many apps available, identifying a trustworthy Bitcoin trading platform can be challenging. Look for these essential features:
- Security measures: Two-factor authentication (2FA), withdrawal whitelisting, cold wallet storage.
- Liquidity: High trading volume ensures faster order execution and tighter spreads.
- User interface: Clean design with real-time charts, price alerts, and educational resources.
- Customer support: 24/7 assistance via live chat or email.
OKX stands out with its comprehensive suite of tools tailored for both novice and advanced traders. From automated trading bots to AI-powered analytics, the platform empowers users to make informed decisions based on real-time market data.

Getting Started: Account Setup & App Access
To begin trading, you’ll need to register on a supported exchange like OKX. Here's what you should know about setup and access:
Registration
- Visit the official website using a secure link.
- Complete identity verification (KYC) to unlock higher withdrawal limits and enhanced features.
Mobile App Usage

Avoid unofficial download sources to prevent phishing attacks or malware infections.
Frequently Asked Questions (FAQ)

A: Yes—through P2P marketplaces on platforms like OKX. You can trade RMB for BTC using bank transfers or digital wallets without intermediaries.
