I have deposit by Skrill(USD). For a trader like me it is normal to withdraw by the way same as Deposit, but by the time I wanted to withdraw my money they told me the only way is by Credit/bank-wire. My bank account and credit card is in AUD, so there would be exchange fee(from USD to AUD). Also there is transaction fee from my account to bank account , and from bank account to my skrill. They are so rude when it comes to withdrawal process and they do not respect the consumer right.
That is really bad mate. Why don't you try the paypal next time. I usually deposit using paypal and so far I do not have any problems. Athough there is a 5 USD amount that will be deducted from the account to withdraw money. But if you withdrawing big amounts that does not matter.
