Cryptocurrency trading has become increasingly accessible, especially with platforms like OKX offering low entry barriers for new and experienced traders alike. One of the most frequently asked questions by beginners is: What is the minimum amount required to place an order on OKX? And how much USDT (often referred to as "U") can you buy at minimum?
In this guide, we’ll break down the essential details about minimum trading amounts, USDT purchase limits, and what you need to know to get started safely and efficiently on OKX.
Understanding Minimum Order Amounts on OKX
When entering the world of crypto trading, knowing the minimum investment required can help you manage your budget and risk effectively. On OKX, the minimum order size varies depending on the trading pair and market type — whether it’s spot trading or futures (contract) trading.
Contract Trading: Low Entry Threshold
For futures or contract trading, OKX offers one of the lowest entry points in the industry. For example:
- The BTC/USDT contract has a face value as low as 0.0001 BTC, which at current prices equates to roughly $6–7 USD (about 40–50 CNY).
- This means traders can start with less than $10, making it highly accessible for those testing strategies or managing smaller accounts.

Most traders use 10x to 20x leverage when starting out, allowing them to control larger positions with minimal capital. However, while leverage increases potential returns, it also amplifies risk — so proper risk management is crucial.
OKX supports two types of margin systems:
- Cross Margin: Your entire account balance acts as collateral.
- Isolated Margin: Limits risk to a specific amount allocated per trade.
Both options give users control over their exposure, depending on their risk tolerance and strategy.
Minimum USDT Purchase Requirements
USDT (Tether), commonly called “U” in Chinese-speaking crypto communities, is a stablecoin pegged 1:1 to the U.S. dollar. It's widely used for trading, hedging volatility, and transferring value across platforms.
So, what’s the minimum amount of USDT you can buy or trade on OKX?
The answer depends on the deposit method and trading pair:
- In spot trading, the minimum order size is typically set at 1 USDT for most major pairs.
- Some advanced trading pairs may require higher minimums, but these are clearly marked in the interface.
- When purchasing via P2P or fiat on-ramp services, minimums vary by payment method and region — usually starting from $10 equivalent.
For precision trading:
- Bitcoin (BTC) trades can go as low as 0.0001 BTC (4 decimal places).
- Ethereum (ETH) supports trades down to 0.001 ETH.
- Other altcoins may have different rounding rules based on liquidity and market depth.
This granular control allows both micro-investors and high-frequency traders to operate efficiently within their preferred ranges.
Is Trading on OKX Safe?
Security is a top concern for any crypto user — especially newcomers. The short answer: Yes, OKX implements robust security measures to protect user assets.
