From what I heard, all the bonus didn't allow the bonus to be withdrawn by the traders. However, the profit made from the bonus can be take out without any issues.

You can withdraw your bonus through the payment systems of your broker. But make sure you will follow the rules before you try to make a withdrawal order.

Try to deposit funds to the processor that is more convenient for you. All the processors require its trader to deposit funds before taking out the profits.

You can't withdraw the bonus straightly. Go trade first and get some profit then you can use a lot of methods to withdraw the profit. Remember though only the amount above the bonus balance can be withdrawn. So try your best to not to get a lot of loss otherwise you'll have a hard time to recover before you can withdraw it.
