FAQ

Cryptocurrency is a decentralized, blockchain-based digital currency. No state body can control the transactions.

Due to cryptographic data protection methods, it is impossible to obtain information about parties involved in transactions.

CREX24 is a professional cryptocurrency exchange platform which has been in operation since 2017.

It unites a number of virtual currencies into one platform.

CREX24 offers low fees, enabling traders to maximize their profit.

No limits are placed on deposits or withdrawals by the exchange site.

Swap is the process by which one cryptocurrency is exchanged for another at a set rate.

Rather than selling one coin to buy another, in the exchange of tokens, one coin is instantly exchanged for a new one. The transaction is therefore compulsory because the holder would otherwise lose money.

The Swap is usually organized by coin developers and requires major technical changes in the blockchain of the required coin.

No action is required on the part of the users.

Deposits, withdrawals, and exchanges are temporarily put on hold during the Swap.

The new wallet is set up. Coins are credited to the new coin holders, and the old coins are debited.

Once complete, deposits, withdrawals, and trades are resumed.

The total value of holdings is the approximate value of all the coins and tokens that a user has in USD or BTC, if converted at the current rate.

If one of the currencies cannot be traded at the moment, the value is zero.

The Android app is available already in Google Play.

The iOS app is currently in development.

Please note:

Your email address can only be changed if your previous account is no longer accessible, or if CREX24 emails are not reaching you.

Once you are registered, you can top up your account with either cryptocurrency or fiat money (RUB, USD, EUR, etc).

If you make an account deposit using cryptocurrency, open your "Account" page, select the coin/token you wish to use, click on the deposit icon (pic. 1), and copy the address generated specially for you.

Use this address only to make a deposit; otherwise, your funds will be lost.

Please be aware of ERC-20 tokens: use the generated address only (pic. 2).

Please pay attention when making a deposit: some tokens and coins have a minimum deposit requirement. Deposits below the required amount will be credited to your account only after the minimum amount has been reached.

There are certain coins which require a special tag when a deposit is made (pic. 3). The tag is required for the deposit; otherwise, the coins will not reach your account.

If you see that an address has not been generated for the coin you have selected,

try refreshing the page a few times. If this does not work, please contact the exchange's technical support.

We urge you to take care when making a deposit. If a deposit is made in error, the transaction is non-refundable.

You make account deposits of your own accord, so we urge you to make sure in advance that all the data you provide is correct (address, amount, message field – if required).

Please also check the ticker and the full name of the coin or token.

When making an account deposit using your QIWI wallet, please remember that payments will not be credited if your Message is invalid or incorrect.

Steps for making an account deposit:

1. In the "Account" section, select a currency and click "Deposit". Choose QIWI as the payment system.
2. You will be taken to your QIWI Wallet page, where you need to confirm the transaction.
3. Review your details: phone number (1), Message (2), and amount (3). Please do not make any changes.
   
   Log in if required.
4. Next, click "Pay".
5. Confirm the transaction and complete payment.

To withdraw funds from your CREX24 account, go to the "Account" page.

Select the currency you wish to withdraw. Enter your details (address, amount, and Payment ID/Message if required). (Pic. 1)

After that, you will receive an email confirming your withdrawal (pic. 2).

(If you did not make the withdrawal request, cancel the transaction in your account and contact the exchange's technical support.)

Once your withdrawal has been confirmed by email, a fund withdrawal window will open automatically from the website (pic 3). If you have 2FA set up, you will first need to enter an authenticator code.

If more than half an hour has passed and your withdrawal has not been confirmed or the hash hasn’t appeared in the Reports section, please contact the exchange's technical support.

If your withdrawal was canceled automatically, check that all withdrawal requirements have been met in full.

Withdrawals will be deemed valid if they meet the following conditions:

1. Your address has been confirmed.
2. You have the amount indicated available in your account (not including active orders). You have indicated 7 digits after the comma, not 8 digits.
3. If you are required to enter a Message when making the withdrawal request, ensure that it is correct and relevant.
4. Addresses may change after a Swap, so ensure that the address is correct for the withdrawal.
5. If you are withdrawing ETH, check that you are not using the contract address.

If all of the above is correct but there is still an issue with the withdrawal, please contact the exchange's Support team.

When withdrawing funds, the required fields need to be completed. The "Address" must contain the current, working address of your wallet or the website/exchange that you want to credit funds to.

Please be aware that if the transaction is successful but your funds are not credited to your other account or wallet, you will need to check that the address you used is correct.

You can contact the exchange/website Customer Support service, as it may be an issue from their side and they will help with crediting the funds.

CREX24 bears no responsibility for the address you enter when making the withdrawal.

You enter the address of your own accord, so we always advise that you check the authenticity of the address. If you are transferring to a wallet, ensure in advance that the link is correct.

As soon as you click “Confirm withdrawal”, the withdrawal process begins automatically. Unfortunately, there is no way to stop it.

If you send funds to an invalid address, use another method to find and/or contact the recipient.

If you transfer funds to another exchange with invalid or empty tags or description, contact the company and provide them with the TxID so that they can refund your money.

The time depends on the network load and average fee of the network.

https://bitinfocharts.com/comparison/bitcoin-transactionfees.html

If the network's average withdrawal fee is significantly raised immediately after the transaction is submitted to the blockchain, then it is possible that the withdrawal will take longer.

But the transaction will be successful as soon as it has gained 1 confirmation.

1. Withdrawals are restricted for 72 hours after the password is changed. Notification will be sent via email.
   If you did not request a new password, please contact Customer Support.
2. There may be suspicious activity from your account.

Withdrawals may be restricted for security purposes. Please contact Customer Support.

Choose the coin/token that you want to buy/sell.

Go to the "Markets" page for the coin you selected (pic. 1).

You will then see the Buy/Sell forms (pic. 2).

Make sure that your coin total is enough to make an order.

You can fill in the "Amount" and "Price" manually or automatically by pressing "Balance" and "Best ask/bid" (pic. 3).

The minimum/maximum order varies according to the coin and trading pair.

https://api.crex24.com/v2/public/instruments?filter=BTT-BTC,DOGE-BTC

The amount can be seen in the "minVolume" field.

The maximum order size is 999,999,999 coins/tokens.

To understand why the balance is not displaying correctly, there are a couple of things that can be checked:

Open the "Reports" page, and in "My orders", you will see whether your order is still active. If it is, then it is likely to be partially executed.

If this is the case, you will need to wait for your order to complete. Once executed in full, you will receive the full amount.

It is also important to note the trading fee .

The time that an order takes to be executed depends on the users.

As soon as somebody buys an order, it is executed.

1. A customer places an order.
2. Another customer buys/sells a coin at the order price.
3. Depending on the purchased/sold coin amount, the order is fully or partially executed.
4. If the order is executed in part, it will be up for longer: until it has been executed in full or canceled.

• Market maker ("Maker"). The Maker places an order (to buy or sell) on the market before a transaction takes place. This creates liquidity in the market (an order book is formed).
• Market taker ("Taker"). The Taker concludes the transaction at the current market offer.

Our exchange company will not advise you to use your CREX account as a long-term wallet. It should be used only as a temporary wallet while trading.

To avoid any inconveniences when withdrawing funds, we ask that you do not accumulate them with the aim of holding them long-term.

We are doing everything we can to keep your funds secure; however, it is important to remember that exchange sites are always being targeted by hackers.

It is important to note that you will need to pass verification in order to deposit fiat money.

There are several payment systems that you can use to make an account deposit.

Verification is not required for ePay or QIWI.

For deposits via WebMoney and Yandex.Money, you will need to upload the following documents:

– Passport/ID

– A photo of your personal account (with your face in the background of the payment system page, and your account number visible on the page)

The following must be provided if making a deposit using Mastercard or Visa:

– Passport/ID

– A photo of your bank card (the one that you used to debit funds)

– A photo of a utility bill

– Your face next to your ID card or the first page of your passport

– A selfie with your bank card

Attention! The information must be clearly visible. Use original documents only.

Once you have made an account deposit, you will be sent an email with verification instructions.

Verification is not required for withdrawing fiat currency. The payment systems you can use are ePay, WebMoney, QIWI, and Yandex.Money.

This feature was created for customers who believe that their account has been, or is currently being hacked. If you notice any suspicious activity in your account, you can block it.

The "Create faucet" feature has been developed primarily for coin developers, but any customer can create a faucet if they want to.

Please note that you will not get any income by creating a faucet.

This feature is designed to promote the use of coins and tokens and make them more popular.

Burning is only possible for coins of which your total holdings is less than the minimum order amount. If the total in your account is higher than the minimum order amount, it is impossible to burn it.

The dust burn feature was created to liquidate coins that cannot be sold.

You can burn your remaining coins if:

• You have an active trading pair
• You cannot sell them, i.e. you do not have enough to reach the minimum order size
• Selling is not prohibited on your account
• You have not exceeded the maximum burning attempts for any of your coins: 5 times in 24 hours (e.g. if you press "Burn" and cancel the process, this counts as one attempt, and you will have 4 attempts remaining)

Mining is not forbidden, but it is not recommended because of the risk of losing coins.

It is best to mine using your wallet and then make a deposit into your exchange account.

If a token that has been deleted is not traded on other exchange websites, you can withdraw the tokens to third-party/hardware wallets.

Information about these wallets is easily available.

Example: https://medium.com/swlh/guide-to-storing-erc-20-tokens-on-popular-wallets-be193e9279dc

1. Open your wallet.
2. Open the debug window.
3. In the next window, find "Current number of blocks".
4. Go to "Console", and for the "getblockhash" command, enter the block number you received and press Enter.
5. When you receive the hash code, go to the coin explorer and enter it in the search bar. Check whether the data corresponds (current data and hash).

There are a number of reasons why we might close a coin:

• For maintenance work (updates to the coin, SWAP, fork, etc.)
• At the developer's request
• If the explorer is malfunctioning
• For delisting
• Because of attacks on the coin network (51%, and others)

There are two coin delisting methods that are used on our exchange:

• The standard delisting process
• Delisting "dead" coins

A coin may be removed from the exchange for the following reasons:

• Hard fork with the transfer of old coins to a new link
• Coin swap
• Attacks on a coin's blockchain
• Lack of access to a coin's website or explorer over a long period of time

Before removing a coin entirely from the exchange, there is a period of up to 30 days in which customers can withdraw their holdings.

• The coin must be fully listed on CMC
• By 1000+ customers in our community (Twitter/Telegram/Discord)

So the bigger the community, the better the chances.
