暗号通貨を迅速に一番お得なレートで交換する

Quickex is an instant cryptocurrency exchange that provides the best crypto-to-crypto rates on the market.

Quickex’s robot is integrated into the largest cryptocurrency trading platforms, including Poloniex, Indacoin, and Bittrex. In the span of milliseconds, the robot makes bids and asks on the trading platforms, then selects and suggests the best available rate and displays the estimated rate on our site. The system fixes the rate for 15 minutes so the user has enough time to make the transaction. Thus, the exchange rate at the time of a transaction equals the estimated rate that you see when you begin a transaction.

We currently accept Bitcoin (BTC), Ethereum (ETH), Ethereum Classic (ETC), Litecoin (LTC), EOS, Bitcoin Cash (BCH). More crypto and fiat currencies are to be added soon.

Yes, we fix the estimate exchange rate for 15 minutes to allow our users to execute their transactions at the expected rate.

A wallet is a vault where you store cryptocurrency (coins and tokens). A wallet address is a randomly generated combination of digits and letters that is associated with a particular wallet. Quickex does not provide wallet addresses and never stores user deposits. To exchange cryptocurrencies on Quickex, you need to provide a wallet address where the exchanged currency can be transferred to after the exchange is over.

Just figure out what coin do you want to buy and seek for a stable wallet that supports this coin. As a rule, each coin has its official wallet client.
Note that each wallet has its unique address or a tag with a private key that is required to restore your wallet if it was lost. Quickex never asks you to disclose your private keys. Store them in a safe place and never show to anyone. Once private keys are stolen, your wallet with all the coins is lost forever.

Destination address is the address of the wallet to which Quickex will send the exchanged cryptocurrency after the exchange transaction is complete. For example, if you want to buy ether (ETH), you should input an ETH wallet address in the corresponding field.

The buying process is the same for all coins available on Quickex: Go to quickex.io and select the coin you want to exchange ("You send" field) on the left and the coin you want to acquire ("You get" field) on the right and click the ‘Exchange’ button. Input the destination address and the refund address. Double-check everything carefully. If everything looks OK, proceed to the next step by clicking ‘Start Transaction’.

Now your transaction has been initiated. The system fixes the rate for 15 minutes to allow you to complete the transaction at the estimated rate.You will see a QR code and a wallet address below. This is the address to which you need to send the currency you want to exchange. Go to the wallet where you’re storing the currency you want to exchange and paste this address into the corresponding field. If you use a mobile wallet app, you can just scan the QR code we provide. As soon as we receive the coins, we’ll exchange them and send them to the destination address you provided in step 2. Usually it takes us 5-30 minutes to complete a transaction. In some cases, wait time may be increased because of network delays.

After transaction is finished, you get a receipt with an output transaction hash (see transaction details). This hash is a proof that your transaction is finished.

Quickex transactions take 5-30 minutes to be processed. If transaction is large (worth over 1 BTC), processing may take longer, depending on the size of your transaction and blockchain capacity.

As a rule, our transactions take 5-30 minutes to be processed. If your transaction takes longer, this could be due to various reasons including:

Blockchain is overloaded. There are many transactions waiting to go through, including yours. This issue occurs on the bitcoin and bitcoin-based blockchains. Unfortunately, the only thing to do is wait it out. Quickex has no control over blockchain overloads.

Coin updates. We may turn off some coins to update their clients. This can take some time. You will get your money as soon as we turn it back on.

DDoS attacks. Every platform is subject to such attacks. Unfortunately, in this case the only thing to do is wait it out.

There are several reasons this might be happening:

The transaction hasn't been included to a blockchain. Cryptocurrencies aren't stable, so minor errors sometimes occur. If this happens we will either refund your money or push the payment through if you can provide the hash of your transaction.

ETC and ETH confusion. The addresses of Ethereum (ETH) and Ethereum Classic (ETC) have the same structure. If you send ETC or ETH, make sure that you've selected the appropriate transaction type on Quickex. For example, if you create an ETH to BTC transaction, make sure you send ETH, not ETC. Otherwise your transaction will get stuck.

Other internal errors. Even our well-made system can lag or experience internal issues. If you believe that might be the case, please report it to support@quickex.io

Unfortunately, blockchain transactions are irreversible. Once a transaction is made (money is sent to a particular wallet address), it cannot be rolled back. If you are going to exchange cryptocurrency, be sure to double-check all payment details carefully before sending.
