This depends on the arrangement Onsi has with your platform and the benefits they provide you with. In some cases there is no cost, in other cases, there will be a cost which we will confirm prior.
You will receive the earnings you've withdrawn minus any fees applied. Fees are subject to change.
In some cases, the platform you work with subsidises the transaction fees for a set number of withdrawals. Any withdrawals made beyond that number will incur a fee.

Transaction fees include VAT.
