What is the Daily Limit for OKX C2C Buying?
OKX C2C buying does not have a fixed daily limit; it is determined by multiple factors: your KYC level, the limits set by merchants, and a 30-day rolling risk control mechanism. How much you can actually buy depends on your account verification level and the merchant you choose.
Prerequisite: Confirm Your KYC Level
Before understanding specific limits, make sure to clarify your account's verification level, as this is the most critical factor affecting how much you can buy. The KYC level directly determines your fiat transaction cap.
How to complete: Go to the [Identity Verification] page and check whether you are at Lv.1 or Lv.2.
Step 1: Understand the Limits by KYC Level
The C2C buying permissions vary with different verification levels:
Lv.1 (Basic Verification): You can engage in C2C buying, but the total limit is relatively limited. When your cumulative buying amount exceeds 20,000 CNY, a video verification reminder will be triggered.
Lv.2 (Advanced Verification, including video verification): After completing video verification, your C2C buying limit is significantly increased, unlocking a higher transaction cap.
Unverified accounts are basically unable to conduct fiat transactions. Completing a higher level of KYC is the most direct way to increase your transaction limits.
How to complete: Know the ceiling of the current level's limit, and whether you need to upgrade to meet your target buying amount.
Step 2: Understand the Single Transaction Limit Set by Merchants
Each C2C order also has an upper limit set by the merchant. Different merchant levels have different permissions:
| Merchant Type | Single Purchase Order Limit | Daily Purchase Limit (Verified <30 days) |
|---|---|---|
| Regular Verified Merchant | 100,000 CNY | 250,000 CNY |
| Merchant Verified ≥30 Days | 2,000,000 CNY | No Limit |
Data source: OKX Official C2C Merchant FAQ
Verified merchants (with blue/green star badges) have a single purchase order limit of up to 100,000 CNY; Diamond merchants (red/purple diamond badges) have a single purchase order limit of up to 150,000 USD (approximately 1,000,000+ CNY).
The minimum amount for regular users in C2C trading is 10 CNY. In the regular section, the typical minimum per order is 100 CNY, with an upper limit of 100,000 CNY.
How to complete: Before placing an order, confirm whether the merchant's single transaction limit meets your needs. If you need a large purchase, prioritize higher-level merchants.
Step 3: Understand the "30-Day Buying Limit" Mechanism
OKX has a 30-day rolling buying limit system. Once exceeded, the excess portion of an order triggers T+N security protection, meaning the purchased assets cannot be withdrawn or sold for N days after the purchase.
Core Rules:
The system calculates your remaining limit based on the cumulative amount of digital assets you have purchased via C2C in the past 30 days.
Purchases within the limit are still subject to real-time risk monitoring by the platform; once the limit is exceeded, the entire order amount will be restricted from withdrawal and C2C selling.
The limit is dynamically adjusted based on a comprehensive evaluation of your account's overall behavior.
Common locking periods:
When the account has zero initial balance, the T+0 limit is only 1,000 USD equivalent assets.
The excess portion follows the T+1 rule, meaning withdrawal is available on the next business day after the order is completed.
How to complete: Before placing an order, pay attention to whether the page shows a prompt like "C2C limit security protection triggered." If there is a prompt, this order will trigger a lock-up period, and you need to accept this restriction before proceeding.
Step 4: Large Transaction Limits (Big-ticket Scenario)
If you need to buy more than 100,000 CNY worth of USDT in a single transaction, you can use the Bulk Trading channel to enjoy higher trading depth. The bulk trading channel has higher entry requirements for users; details can be found on the OKX C2C bulk trading page.
FAQ and Risk Reminders
"Are the buying limit and withdrawal limit the same?": Not exactly. Buying has a 30-day rolling limit, while withdrawals have separate T+N restrictions. For example, if the buying limit is exceeded, the order will trigger a withdrawal lock-up period.
"Can I lift the T+N lock-up early?": No. Once triggered by the system, it cannot be appealed to lift early; you must wait for the lock-up period to end.
"How often does the limit reset?": It is calculated on a 30-day rolling basis. The daily limit depends on the cumulative purchase amount over the past 30 days, not a fixed monthly reset on the 1st.
Go to the [C2C Buy] page in the OKX App, and before placing an order, check if there is a "Trigger C2C Limit Protection" prompt. If there is no prompt, this order will not trigger a lock-up period. If you plan to buy a large amount, first confirm that your KYC level meets the requirement, then choose a high-level merchant with sufficient single transaction limit.
