You will need to have a verified account.
Verification involves providing:
1- Some sort of government issued Identification like ID,DP,PP
2- Some sort of address verification document like a utility bill or tax statement or bank statement
You should be able to withdraw to Bank without a deposit once verified. Although given the amount it might not make sense as there are normally fees associated with any bank transfer.
For other methods of withdrawals like Credit Cards, Skrill, Netteller or
paypal you would need to make at least 1 minimum deposit via method first.
888 makes it simple to know what methods are available to you just check your cashier withdrawal page and you will see your available options. If a method needs a deposit first you will not see it on withdrawal page.
