Perpetual Contract USDT-M: Position Value * Funding Rate (Position Value = Par Value * Contract Quantity * Mark Price) COIN-M: Position Value * Funding Rate (Position Value = Par Value * Contract Quantity / Mark Price).For example: USDT-M Example: Par Value: 100USD/Cont ; Funding Rate: 0.01% ; The Mark Price at 08:00 is 20,000 USDT. A holds 1 long positions, and B holds 1 short positions A Funding fee (deducted)= 1 * 100 * 20,000 * 0.01% = 200 USDT B Funding fee (received)= 1 * 100 * 20,000 * 0.01% = 200 USDT COIN-M Example: Par Value:100 USD/Cont ; Funding Rate: 0.01% ; The Mark Price at 08:00 is 10,000 USD. A holds 100 long positions, and B holds 50 short positions Based on the above information, the fees are calculated as follows: A Funding fee (deducted)= 100 * 100 / 10,000 * 0.01% = 0.0001 BTC B Funding fee (received)= 50 * 100 / 10,000 * 0.01% = 0.00005 BTC

The fee structure differs for each type of trade, as detailed below. <a href="https://www.bydfi.com/en/spot/btc_usdt" target="_blank">Spot Trading </a>FeesSpot trading fees are based on the Maker/Taker fee model. A Maker fee applies when a limit order is placed in the order book and waits to be matched, while a Taker fee is charged when an order is immediately matched with an existing market order.<table style="width: auto;"><tbody><tr><th colspan="1" rowspan="1" width="169.04" style="text-align: center;">Trading Type</th><th colspan="1" rowspan="1" width="107.02" style="text-align: center;">Maker Fee</th><th colspan="1" rowspan="1" width="98.4" style="text-align: center;">Taker Fee</th></tr><tr><td colspan="1" rowspan="1" width="auto" style="text-align: center;">Spot Trading</td><td colspan="1" rowspan="1" width="auto" style="text-align: center;">0.1%</td><td colspan="1" rowspan="1" width="auto" style="text-align: center;">0.1%</td></tr></tbody></table>FormulaSpot Trading Fee = Trade Amount × Trading Fee RateFor example, if BTC’s current price is 40,000 USDT, Trader A uses 20,000 USDT to buy 0.5 BTC via a market order, while Trader B sells 0.5 BTC using a limit order.Trader A (Taker) fee calculation: 0.5 BTC × 0.1% = 0.0005 BTCTrader B (Maker) fee calculation: 40,000 × 0.5 BTC × 0.1% = 20 USDTTrading fees are charged in the traded asset. If you buy BTC, fees are deducted in BTC, while if you sell BTC, fees are deducted in USDT. Unfilled or canceled orders are not subject to trading fees. <a href="https://www.bydfi.com/en/spot/btc3l_usdt" target="_blank">Leveraged Token </a>FeesLeveraged tokens incur a 0.2% trading fee when buying or selling, deducted in USDT.FormulaLeveraged Token Fee = Trade Amount (USDT) × Trading Fee RateFor example, if a trader buys 10 USDT worth of BTC3L, the fee calculation is: 10 × 0.2% = 0.02 USDTAdditionally, a daily management fee of 0.03% is charged at 00:00:00 (UTC+8), which directly impacts the Net Asset Value (NAV) of leveraged tokens but does not reduce the number of tokens held. If a user does not hold leveraged tokens at the time, no management fee is charged. Perpetual Contract (USDT-M & COIN-M) FeesPerpetual contracts follow the Maker/Taker fee structure and fees apply to both opening and closing positions.<table style="width: auto;"><tbody><tr><th colspan="1" rowspan="1" width="330.91" style="text-align: center;">Trading Type</th><th colspan="1" rowspan="1" width="118.02" style="text-align: center;">Maker Fee</th><th colspan="1" rowspan="1" width="120.4" style="text-align: center;">Taker Fee</th></tr><tr><td colspan="1" rowspan="1" width="auto" style="text-align: center;">USDT-M &amp; COIN-M</td><td colspan="1" rowspan="1" width="auto" style="text-align: center;">0.02%</td><td colspan="1" rowspan="1" width="auto" style="text-align: center;">0.06%</td></tr></tbody></table><a href="https://www.bydfi.com/en/swap/btc-usdt" target="_blank">USDT-M Perpetual Contract</a> Fee CalculationOpening Fee = Trade Size × Entry Price × Trading Fee Rate Closing Fee = Trade Size × Exit Price × Trading Fee RateThe formula for calculating the total trade amount: Trade Size (Contract) × Entry Price = Total Trade Amount (USDT) <a href="https://www.bydfi.com/en/swap/btc-usd" target="_blank">COIN-M Perpetual Contract</a> Fee CalculationOpening Fee = (Contract Size × Contract Multiplier ÷ Entry Price) × Trading Fee Rate Closing Fee = (Contract Size × Contract Multiplier ÷ Exit Price) × Trading Fee RateFor COIN-M contracts, the Contract Multiplier = 1.Contract Size is calculated as Coin Amount × Entry Price. Spot Trading Bot FeesSpot trading bots incur fees based on the trade type. Spot Grid Trading and Spot Martingale Strategy follow the Maker/Taker fee structure, while Spot Investment is charged based on market order fees. Spot Grid Trading Fee CalculationFee = Trade Amount × 0.1%Spot Investment Fee CalculationFee = Purchase Amount × 0.1%For the Spot Martingale Strategy, the fee depends on the order type. Market orders incur Taker fees, while limit orders follow Maker/Taker fee rates. Futures Grid Trading FeesFutures Grid Trading follows the Maker/Taker fee model, where fees depend on how the order is executed.<h3>Formula</h3>Futures Grid Fee = Trade Amount × Maker/Taker Fee RateIf an order is placed as a Maker, the Maker fee applies.

The reasons for delisting may be due to a project's decision to cease operations, failure to meet listing requirements, lack of liquidity, hard fork, or reverse split resulting in new coins. There are many factors that may affect an exchange's decision to delist a listed asset. Delisting ProcessWhen an asset is delisted, all trading pairs associated with it will be suspended and removed. Prior to the suspension of trading, the exchange will issue an official announcement to notify all users. Before the delisting, users can still trade until the trading is suspended. It should be noted that during the 10 minutes prior to the suspension of trading, users are not allowed to open new positions. Users are only allowed to close positions during this period.We reserve the right to suspend trading 10 minutes in advance. The precise time for suspending trading shall be subject to the announcement.If users choose to hold their positions until trading is suspended, the system will automatically settle the position. All unrealized profits and losses will be calculated and converted into realized profits and losses during settlement.We recommend that users close their positions before trading is suspended to avoid automatic settlement of positions. We recommend that users join our <a href="https://t.me/BYDFiEnglish/274640" target="_self">community</a> or follow the <a href="https://www.bydfi.com/en/support/ANNOUNCEMENT" target="_blank">latest announcements</a> to obtain the latest information

Here are some frequently asked questions and answers regarding the upgraded perpetual contract bonus system: <h3>1️⃣ Why does my available balance appear normal, but the order fails with the message "Bonus cannot be used alone"?</h3>This means your account only contains bonus funds and no actual cash balance. The system does not allow opening positions using bonus alone. Please deposit additional funds and try again. <h3>2️⃣ Why can't I open a new high-leverage position, even though I already hold one? The system says "Leverage has exceeded the maximum limit."</h3>There are two possible reasons:<ol><li>When you first opened the position, your cash + bonus total equity was above the platform threshold. Later, due to funding fees or trading fees, your equity dropped below the limit, triggering the restriction.</li><li>You didn’t have bonus at the time of opening the position, but later received bonus funds, which caused your total equity to fall below the limit, triggering the restriction.</li></ol>For more details, please refer to <a href="https://www.bydfi.com/en/support/FAQs/articles/0mh1mmncm67a" target="_blank">How to Use Bonus</a>. <h3>3️⃣ Why does the bonus used during closing exceed the original deduction ratio?</h3>If your cash balance is insufficient, the system will automatically use bonus funds to cover the shortfall, which may cause the bonus usage to exceed the expected ratio. <h3>4️⃣ The bonus is not supposed to cover liquidation fees — why was it still used during liquidation?</h3><ul><li>In cross margin mode, bonus is considered part of the margin calculation and may be used during forced liquidation.</li><li>In isolated margin mode, if your cash balance is insufficient, the bonus will be used as a fallback to cover losses.</li></ul> <h3>5️⃣ When am I unable to transfer funds out of my account?</h3>If your account holds bonus funds and there are active positions or pending orders, the bonus is considered "in use" and asset transfers will be restricted. Please close your positions or cancel your orders before transferring funds. <h3>6️⃣ Why was my bonus cleared after I successfully transferred out funds?</h3>According to platform rules, if you transfer funds while holding bonus, the system will automatically clear your bonus. A pop-up confirmation will appear before the transfer — please review it carefully. <h3>7️⃣ Why were my pending orders canceled when my bonus expired?</h3>If the bonus expires while still in use, the system will first cancel pending orders to reclaim the bonus. If canceling orders is not enough, the system will force close positions at market price to complete the recovery. <h3>8️⃣ Why can't I use my bonus wallet? </h3>All new bonus funds are now issued to the default wallet. The bonus wallet no longer supports transfer in or trading, but any remaining cash can still be transferred out. 👉 For more details, check the link <a href="https://www.bydfi.com/en/support/FAQs/articles/0mh1mmncm67a" target="_blank">here</a>.

This enables the agent and the new user to receive a commission on transactions. Below are instructions and examples on how to use a two-way commission link. Generating a Two-Way Commission Link Basic Settings1. Invitation Code : Default Invitation Code: The system generates a 6-digit alphanumeric invitation code.

 • If the deposit failure was caused by the user's maloperation, &nbsp;asset recovery services are not generally provided.
 • In order to recover the user's great loss of assets due to maloperation, BYDFi will assist you in retrieving assets within a certain range. However, the retrieval operation requires a lot of manpower, time, and risk control costs; we may need technical personnel to carry out complex technical operations such as importing and exporting the wallet software, and the entire process may take more than one month.
 • Please provide the following information: username, deposit tokens, deposit address, amount, TXID, &nbsp;and a screenshot of your deposit page.
 • We will ask our relevant department to determine whether it meets the retrieval requirements or not after receiving the required information from you. If you meet the requirements, we will notify you to deposit the retrieving gas fee to our platform address, and you need to contact our customer service after completion.
