The BC Vault cryptowallet (v1.4 or higher) features complete in application integration with the Changelly exchange. Now you can comfortably and securely exchange between crypto currencies you hold on the BC Vault crypto wallet.


How to exchange the currencies?


With BC Vault everything is done without leaving the application itself and the funds will go directly from your BC Vault wallet to your other BC Vault wallet (or any other destination address if you so wish).


  1. Make sure you are using BC Vault firmware and application v1.4 or later

  2. Go to your wallet from where you would like to exchange your funds from.

  3. Click on the "Exchange" icon:
    Select the destination currency and fixed of floating rate (both are explained below) of exchange and click "Next":

    1. Fixed rate - A fixed exchange rate is a rate that totally matches with the amount displayed to the user at the beginning of the exchange, independently from further rate volatility. Due to the volatile nature implementing fixed rates can be very risky for the exchange. Minimum amount for exchange is slightly larger than with floating rates. Your destination wallet will get exactly the advertised amount.

      PROS: You know the amount you are going to get from the very beginning of the exchange.
      CONS: You pay an extra fee for eliminating risks. If the market goes up during the transaction, the rate won’t raise along with it, hence you won’t get additional revenue.

    2. Floating rate - During the standard flow, any transaction has its own unique exchange rate. Due to the volatile nature of the cryptocurrency market, ever-changing network fees, the floating rate might change any other second. As a result, you might receive more or less than you thought you would. Your destination wallet will get approximately the advertised amount.

      PROS: As a rule when exchanging one crypto for another using the floating rate mechanism, the exchange service offers the best rate on the market plus the user pays the minimum possible fee. Moreover, if the market fluctuations play into your hands, you may get a more significant amount of the desired crypto than the amount that was displayed at the very beginning of the exchange.
      CONS: You should always take into account the volatility risks. As the rate may change both in positive and negative ways, you may either get some extra income or less than expected.
