In order to maintain a robust spot trading environment, we constantly monitor the performance of all listed projects and review their listing qualifications on a regular basis. Based on feedback from users and the BitUBU Token [Delisting / Hiding Guideline](https://help.bitubu.com/portal/en/kb/articles/bitubu-token-delisting-hiding-guideline), we will be delisting several projects that do not fulfill our listing criteria.

**The affected projects are as follows:**

SWRV-USDT, EDEN-USDT, STRK-USDT and ELT-USDT

**Execution time:**

We will delist the above-mentioned projects at 6:00 - 6:30 AM UTC on May 22, 2023. Users are advised to cancel orders pertaining to these pairs before the delisting. If your order is not canceled in time, it will automatically be canceled by the system. This procedure may take 1-3 working days. Once the delisting is complete, you can find your assets under Wallet > Funding > Untradable assets.

We take a snapshot of users' all crypto assets at 4:00 pm UTC+8 daily and convert the value to USDT, then to BTC based on the daily average price of BTC/USDT (BTC/USDT middle price = [opening price + closing price]/2).

Snapshot assets include Trading Account and Funding Account. Assets borrowed for leverage or loan are excluded.

We will continue to monitor all listed projects and implement the delisting/hiding mechanism as necessary. For any inquiries regarding this delisting update, please feel free to contact us in [Support Center](https://bitubu.com/support).

|-------|--------------|-----|------------------------|---------|-------|
| lvl1  |  < 100,000   |  /  |     < 1,000,000        | 0.030%  | 0.060%|

| Lvl4  |  ≥ 100,000   |  /  |     ≥ 50,000,000       | 0.015%  | 0.045% |
| Lvl5  |  ≥ 500,000   |  /  |     ≥ 100,000,000      | 0.010%  | 0.030% |

**Total asset balance**

We take a snapshot of users' all crypto assets at 4:00 pm UTC+8 daily and convert the value to USDT, then to BTC based on the daily average price of BTC/USDT (BTC/USDT middle price = [opening price + closing price]/2).

Snapshot assets include Trading Account, Funding Account and Grow. Assets borrowed for leverage or loan are excluded.

**30-day trading volume (USD)**

We calculate the total 30-day volume of all your futures trades in BTC according to BTC/USD price. Every 24 hours, we convert the total volume to USD according to the average price, which is the halved sum of open and close prices. We settle it at 16:00 UTC daily.

Let's say, you traded BTC, ETH, and ETC crypto-margined futures within the last 30 days. We'll convert your trading volume to BTC equivalent according to BTC/USD rate and then convert to USD according to the average price. Then we'll settle the volume at 16:00 UTC.

**Makers and takers**

Maker order is the limit order which enters into the order book before it can be traded in market. For example, if the current BTC lowest ask price is 1,000 USDT and you create a maker order with a bid price 999 USDT, this order cannot be filled immediately. Then it will enter into the order book until someone fills it. After filled, you're required to pay the maker fee and taker will pay the taker fee (or vice versa). You need to pay the taker fee when your limit ask order is traded successfully.

**Trading fee rules**

Calculation formula of trading fee: Trading fee of USDT-margined Futures = Fee rate × (Number of contracts × Multiplier × Face value per contract × Fill price).

Deduction rule of crypto: Trading fee of USDT-margined Futures is settled in USDT and is charged when the order is filled;
Take Futures BTCUSDT (Face value is 0.01 BTC, Multiplier is 1) as an example, assuming the current price of BTC is 20,000 USDT;
Trader A (Trading fee tier is Lv 1) bought/sold 100 contracts (1 BTC) at market price with 10x leverage, and used 2,000 USDT (0.1 BTC) as margin. Trader A became a taker of this trade, so the Trading fee = 0.06% × (100 × 1 × 0.01 × 20,000) = 12 USDT;
Trader A bought/sold 100 contracts (1 BTC) at limit price with 10x leverage, and used 2,000 USDT (0.1 BTC) as margin. Trader A became a maker of this trade, so the Trading fee = 0.03% × (100 × 1 × 0.01 × 20,000) = 6 USDT.

Settlement Futures fee: 0.03% for all users regardless of tier level.

Forced liquidation Futures fee: Calculated according to the taker fee of user's current tier level.

**24h withdrawal limit (USD)**

24h withdrawal limit is the maximum amount of crypto you can withdraw within 24 hours, in USD equivalent. If you want to increase your limit, please contact Bitubu support.

For example. Your 24h withdrawal limit is 300 USD. After withdrawing 250 USD, 25 USD equivalent in OMG, and 15 USD equivalent in XUC, you'll have a 10 USD limit remained for withdrawal within 24 hours. If you want to withdraw 20 USD equivalent in XRP, which exceeds 10 USD limit, you can withdraw until the next day. Alternatively, you can contact our customer support to increase your limit tentatively.

24h withdrawal limit is different under different KYC levels. For KYC Level 1, the limit is ≤ 2,000 USD. For KYC Level 2, the limit is ≤ 10,000 USD. For KYC Level 3, the limit is ≤ 500,000 USD.

**Daily update time of trading fee**

Bitubu updates the latest level of user's trading fee at 9-11 pm (UTC)
