How long does the exchange rate remain valid? Why exchange rate has been recalculated? What is volatility?

For your convenience, ALFAcashier fixes the exchange rate for 5 minutes. It means if you send the funds within 5 minutes and the transaction goes into the network, the exchange rate remains the same, even if your transaction "gets stuck". Althrough the maximum time is 2 hours for all unconfirmed transactions. If your transaction isn't confirmed in 2 hours - rate will be updated as well.

So, there are 2 rules:

payment should be sent within 5 minutes after you've created a new order
unconfirmed transaction(s) should be confirmed within 2 hours or less

If you do follow these 2 simple rules - exchange rate of your order won't be updated, otherwise the exchange rate will be recalculated at the time when we do receive your payment or when transaction gets confirmed.

The term "volatility" means how quickly and to what degree the price of a particular asset changes over time.

We hope you will enjoy the simplicity and convenience of our service.

ALFAcashier team.
