Is there an opportunity to withdraw bonus funds from the account?

Yes, you can withdraw bonus funds after the bonus has been traded. The size of the trade turnover is equal to the bonus multiplied by the leverage.
The amount of the bonus affects the volume of trading turnover:
if the bonus amount is less than 50% of the Deposit amount, the trading turnover leverage will be 35%;
if the bonus amount is 50% or more of the Deposit amount, the trade turnover leverage will be 40.
You can find more detailed terms of bonus accrual by visiting the Deposit introduction page “https://binomo.com/cashier”, after the Deposit method is selected, and using the link with “information about bonuses”. You can follow the process of trading on a bonus by visiting the trade page, “Gifts” section.
