Cryptocurrency trading has evolved into a mainstream financial activity, and choosing the right platform is crucial for both beginners and experienced traders. OKX, formerly known as欧易 (Ouyi), stands out as one of the world’s leading digital asset exchanges, offering a secure, intuitive, and feature-rich environment for buying, trading, and managing cryptocurrencies like Bitcoin (BTC), Ethereum (ETH), USDT, XRP, and over 400 other digital assets.
Whether you're just starting your crypto journey or looking to scale your investment strategies with advanced tools, OKX delivers a comprehensive ecosystem that includes spot and derivatives trading, Web3 wallets, NFT markets, DeFi integration, and powerful APIs for automated trading.
Why OKX Stands Out in the Crypto Space
As a global platform serving millions of users across 200+ countries, OKX combines cutting-edge technology with user-centric design. Its reputation is built on three core pillars: security, performance, and accessibility.
The exchange supports fast deposits and withdrawals across multiple blockchain networks, offers real-time market data with professional-grade charting tools powered by TradingView, and provides instant price alerts to keep you ahead of market movements.

Comprehensive Trading Solutions for Every Investor
OKX caters to all levels of crypto enthusiasts — from first-time buyers to institutional traders.
Spot & Derivatives Trading
Trade major cryptocurrencies like BTC, ETH, SOL, and LTC with low fees and high liquidity. The platform offers:
- Spot trading with over 400 trading pairs

Web3 Integration & Multi-Chain Support
With built-in Web3 wallet functionality, OKX enables seamless interaction with decentralized applications (dApps) across 100+ blockchain networks, including Ethereum, Solana, Polygon, Arbitrum, and OKX’s own OKC chain.
You can swap tokens via an intelligent aggregator that scans 400+ decentralized exchanges (DEXs) and 20+ cross-chain bridges to find the best rates — all within a single interface.
Security First: Protecting Your Digital Wealth
At OKX, asset protection is not just a promise — it's engineered into every layer of the platform.
- Cold wallet storage secures the majority of user funds offline
- Multi-signature hot wallets with semi-offline signing reduce exposure to online threats
- SSL encryption, two-factor authentication (2FA), and biometric login options enhance account security
- Regular third-party audits ensure transparency and trust
Additionally, OKX maintains a Proof of Reserves system, allowing users to verify that their assets are fully backed at all times.

The OKX mobile app brings full trading capabilities to your fingertips, whether you're using iOS or Android devices.

Frequently Asked Questions (FAQ)
Q: Is OKX safe for storing my crypto?
A: Yes. OKX uses industry-leading security practices including cold storage, multi-signature technology, and regular audits. However, for long-term holdings, using a private hardware wallet is recommended.
Q: Why don’t I see ERC20 or TRC20 network options anymore?
A: Network labels have been updated for clarity. Instead of "ERC20", you’ll now see "Ethereum", and "Tron" instead of "TRC20". This change helps users better identify the underlying blockchain when depositing or withdrawing funds.
Q: Who pays the withdrawal fee?
A: The sender pays the withdrawal fee. Receiving funds (deposits) is always free on OKX.
Q: My withdrawal hasn’t arrived — what should I do?
A: Verify that you selected the correct network (e.g., Ethereum vs. BSC) matching the recipient’s address. Cross-chain mismatches are the most common cause of delayed or lost transactions.
Q: Can I trade without KYC?
A: Yes, basic trading is available without full identity verification. However, completing KYC unlocks higher limits, C2C trading, and additional financial services.
Q: How do I know if an email or link is really from OKX?
A: Only trust communications from @okx.com domains. Never share your password, 2FA codes, or recovery phrase. Always check announcements in the official app or OKX Support Center.
