No need to do anything special: just make a deposit using the "Cashier" section on the Binomo platform ("Deposit" button in the top right corner). The funds will be automatically converted to the currency your Binomo account uses.

Binomo never charges you any currency conversion fee. Funds are exchanged at the current rate of the bank serving the payment. You will always be able to check the amount in the target currency before confirming the payment.
