The prices are calculated and are held for 120 seconds. The
service exchange rate is adjusted to mitigate the risks
connected with price fluctuations. At any given moment, you
input the amount of money you wish to spend and you see the
amount of bitcoin you can receive, according to the service
exchange rate, or vice versa. If the situation on the market
allows the execution of your order on conditions not worse
than you agreed on, the order will be filled. The order can
also be filled on more favorable conditions.
If there is a sudden spike in the exchange rate — preventing
the execution of the order on the agreed conditions — you
will be notified upon the submission of the order. After you
confirm the buy, your order is matched to other orders on
the exchange — sometimes the amount can be even greater than
agreed on, but is never smaller. The service works on a
Fill-or-Kill order type.
