Why have I been asked to resubmit my selfie for Profile Verification?

If you have received an email from us asking you to re-upload your selfie, this means that unfortunately, the selfie you submitted could not be accepted by our compliance team. You will have received an email from us explaining the specific reason why the selfie was not acceptable.

When submitting your selfie for the profile verification process, it is very important to ensure the following:

  •  The selfie is clear, unblurred, and in color,
  •  The selfie is not scanned, re-captured, or modified in any way,
  •  There are no third parties visible in your selfie or liveness reel,
  •  Your shoulders are visible in the selfie,
  •  The photo is taken in good lighting and no shadows are present.

Ensuring the above will enable us to process your application faster and smoother.

Can I submit my ID documents/selfie for Profile Verification (KYC) via live chat or email?

Unfortunately, due to compliance and security reasons, we cannot personally upload your profile verification (KYC) documents via live chat or email.

We adhere to high security and compliance practices, so we believe in and encourage our users to submit their applications with minimal involvement by outside parties.

Of course, we can always provide support and suggestions on the process. We have extensive knowledge of what documents are most likely to be accepted and verified with no problem.

How long does Address Verification take?

When it comes to submitting a valid proof of address document to verify your address, please note that wait times are typically up to 24 hours; although this may take a little longer when we have a higher volume of documents to review.

Our compliance team is constantly working hard to review all verification documents in the order that they have been received by us, and it is not possible to have your documents prioritized as we value each and every one of our customers.

Please rest assured that our team will review your documents as soon as possible. In the meantime, we thank you for your patience whilst the team checks all submissions as fast as they can.

Once the review has been completed, you will receive an email with the outcome.

Liquidation Protocol


BTCEX uses the Mark Price to avoid unnecessary liquidations and to combat market manipulation.

What is the difference between Mark Price and the Last Price?

To avoid spikes and unnecessary liquidations during periods of high volatility, BTCEX Futures uses the Last Price and Mark Price.

The last Price refers to the latest transaction price the contract was traded at. In other words, the last trade in trading history defines the Last Price. It’s used for calculating your realized PnL (Profit and Loss).

On the other hand, Mark Price is calculated using a combination of funding data and a basket of price data from multiple spot exchanges. Your liquidation prices and unrealized PnL are calculated based on the Mark Price.

Risk and leverage are adjusted based on the user’s absolute exposure; the larger the position, the higher the required margin, and the lower the leverage. A liquidation is triggered when:

Collateral = Initial Collateral + Realized PnL + Unrealized PnL

It is important to note that the maintenance margin change will directly affect the liquidation price. To avoid being liquidated (i.e. margin ratio hits 100%), please add more margin or reduce your positions. It is recommended to control the margin ratio below 80%.

Liquidation Price

Liquidation occurs when the Mark Price hits the liquidation price of a position. Traders are advised to pay close attention to the movements of the Mark Price and the liquidation price to avoid being liquidated.

BTCEX allows highly leveraged trading by using a sophisticated risk engine and liquidation model. The liquidation model might be intricate.

What happens during liquidation?

During the liquidation process, all open orders are immediately canceled. All users will be subjected to the same liquidation protocols referred to as “Smart Liquidation.” BTCEX takes full liquidation of a user’s position. For any traders that are cleared via forced liquidation and not by an order issued by the user, a liquidation fee will be charged on the amount liquidated.

It is important to mention that, as a general rule, users who hold small positions that enter liquidation are highly likely to be entirely liquidated. Users with larger accounts will see a smaller percentage of their accounts liquidated compared to smaller users. This is because the Maintenance Margin is based on a user’s position amount and not their leverage selection. As a result, the effective Maintenance Margin for smaller users is lower than the liquidation fee rate. As such, they are already bankrupt when first entering liquidation, regardless of the final price when clearing.

Liquidation orders

Note that all orders for liquidations are Immediate or Cancel orders. The order will fill as much as possible and cancel the rest.

The user’s position will be closed at the bankruptcy price, and the Insurance Fund will take over the position, and the user is declared bankrupt. A portion of the remaining collateral (if any) will go to the Insurance Fund. If an account becomes bankrupt (negative wallet balance), the Insurance Fund will payout to balance the account back to 0.

Automated Negative Balance Clearance

When a user’s account balance falls into negative equity, BTCEX will use the Insurance Fund to cover the deficit losses in the user’s account. The automated negative balance clearance will be performed every ten minutes.

Please note the negative account balances will be automatically cleared for users who meet all the requirements below:

For negative balances in USDT-margined accounts, there are no open positions (cross or isolated) in the account.

  • The user did not transfer him/herself to deficit losses in his/her account after liquidation.
  • In cases where you did not meet the criteria stated above, please contact our Customer Service agents for assistance.

Insurance Clear Fee

When a user’s position is liquidated, a certain percentage of the Insurance Clear fee will be collected and contributed to Insurance Fund reserves, marked as ’’Insurance Clear’’ in the Transaction History.

Since the liquidation price will not change, it is recommended that users strictly control their position risks to avoid liquidation.
Please note:
  • The Insurance Fund will take over the liquidation positions at the bankruptcy prices, and the bankruptcy prices may be out of the contract’s market price range but the bankruptcy price will not show on the K-line.
  • We will send margin call and liquidation call notifications by mail, text message, and internal message. The notifications serve as a risk warning and cannot guarantee timely delivery. You agree that during your use of the Service, under certain circumstances (including due to personal network congestion and poor network environment), users may be unable or delayed to receive SMS or e-mail reminders. BTCEX reserves the right with no obligation to deliver notifications.

Mark Price Index Price

The calculation of Mark Price is intricately linked to the Funding Rate. Unrealized PnL is the primary driver of liquidations. It is important to ensure that the Unrealized PnL calculation is accurate to avoid unnecessary liquidations.The underlying contract for the Perpetual Contract is the ‘true’ value of the Contract, and an average of the prices on the major markets constitutes the “Price Index,” which is the primary component of Mark Price.

BTCEX Index Price derives from Binance, Bitfinex, Bitstamp, Bittrex, Coinbase, Exmo, Gate, Gemini, Huobi, Kraken, Kucoin, Mxc, Okex, Poloniex. The highest and lowest prices are also removed before calculating the average.

Now that we’ve computed the Price Index, which can be considered as the “Spot Price,” we can move forward in calculating the Mark Price, which is used for all Unrealized PnL calculations. Note that Realized PnL is still based on the actual executed market prices.
Frequently Asked Questions (FAQ) in BTCEX

Mark price formula for perpetual futures contracts is as follows:

Mark Price = Median* (Price 1, Price 2, Contract Price)

Price 1 = Price Index * (1 + Last Funding Rate * (Time Until Funding / 8))

Price 2 = Price Index + Moving Average (30-minute Basis)*

Contract Price = (Bid1 + Ask1) / 2

*Median: If Price 1

*Moving Average (30-minute Basis) = Moving Average ((Bid1 + Ask1) / 2- Price Index), which measures every minute in a 30-minute interval

Please note that due to extreme market conditions or deviations in price sources, which may lead to mark price deviating from the spot price, BTCEX will take additional protective measures, i.e., Mark price = Price 2 in this scenario.

Mark Price is a better estimate of the ‘true’ value of the contract than Perpetual Futures prices, which can be more volatile in the short term. We use this price to prevent unnecessary liquidations for traders and discourage poor actors’ market manipulations.


1. BTCUSDT Index Price = [(BTCUSDT of Exchange 1) + (BTCUSDT of Exchange 2) + (BTCUSDT of Exchange 3) + ......] / Total Exchange Number

2. In the event of extreme price volatility or deviation from the price index, BTCEX will undertake additional protective measures, including but not limited to changing the constituents of the price index.

3. BTCEX reserves the right to update the Price Index references from time to time.

What does "Maker" or "Taker" Mean?


When you place an order that goes on the order book partially or fully, such as a limit order, any subsequent trades coming from that order will be as a “maker.”

These orders add volume to the order book, helping to "make the market," and are therefore termed the "maker" for any subsequent trades.


When you place an order that trades immediately, by filling partially or fully, those trades will be "taker" trades before going on the order book.

Trades from Market orders are always Takers, as Market orders can never go on the order book. These trades are "taking" volume off the order book, therefore called the "taker."


What is Withdrawal Fees Minimum Withdrawal Amount?

Crypto Withdrawal Fees

There are typical "Transaction Fees" or "Network Fees" associated with withdrawals to crypto addresses located outside of BTCEX. This fee is sent to the miners or validators in charge of executing the transactions and maintaining the security of the relevant blockchain network, not to BTCEX.

To make sure that transactions are executed, BTCEX must pay these fees to the miners. Due to the dynamic nature of transaction costs, you will be billed by the state of the network. The fee amount is calculated using an estimate of the network transaction fees and is subject to sudden changes due to a variety of circumstances, including network congestion. Please verify the most recent charge, which is displayed on each withdrawal page.

Minimum Withdrawal Amount

Every withdrawal request has a minimum requirement. On the withdrawal page, you may view the current transaction costs and the minimum withdrawal amount. Please take note that owing to unforeseen circumstances like network congestion, the minimum withdrawal amount and fees may change without prior warning.
Frequently Asked Questions (FAQ) in BTCEX
As was the case at the time of this article’s publishing, the minimum withdrawal amount for ETH is 0.0072 ETH, and the transaction fee is 0.0036 ETH.

Please be certain to choose the right network. Before completing the withdrawal, you must select the ERC20 option if the address you wish to send the money to is an ERC20 address (Ethereum blockchain). Don’t pick the choice with the cheapest price. The network you choose must work with the withdrawal address. You will lose your assets if you select the incorrect network.

Withdrawal Fees?

The blockchain network controls withdrawal rates, which can change at any time due to things like network congestion.
