ChangeHero charges a quite low commission fee (0,5%) and offers the best available rate at the moment the transaction is completed. The rates remain approximate until the transaction is actually made on the blockchain. The exchange rate at the time of a transaction may slightly differ from the estimated rate you see when you begin a transaction.

Usually, our transactions take 5-40 minutes to be processed. It your transaction takes longer, this could be due to a variety of factors, including:

  • Blockchain 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. ChangeHero has no control over a blockchain overload.
  • Coin updates. We may turn off some coins to update a client. This can take some time. ou 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.
It is vital to have at least one wallet to exchange your funds at ChangeHero. Different wallets are specifically tailored for different operations with the transactions. There are official wallets, web purses and other applications. For each currency you need to have a separate wallet. The address of the wallet is a unique combination of numbers and letters from 26 to 35 characters.
When you decide which coin you would like to acquire, find a reliable wallet. Each coin has an official one. When you create a wallet, you automatically get an address and a private key. Keep your private key to yourself and don’t show it to anyone for security reasons.
Each transaction is registered in the blockchain and has its own unique identification code, called a Hash (also referred as “TX”). This unique code allows you to verify its validity in the blockchain open ledger.
Blockchain operations are irreversible. If the funds are sent, the transaction cannot be canceled by anyone. Therefore, thoroughly check all the payment details before sending money.
There are no limits for cryptocurrency exchanges on ChangeHero. However for the transaction to be carried out, the fee is charged by the blockchain itself. The amount sent must be sufficient to cover all the blockchain fees.
