If i understand right, the OP deposited money. It means that he hasn`t any restrictions with gambling in his country/state. So i don`t see any problem to deposit some small sum using Visa/MasterCard(for example) and withdraw money same way. In such a way he`ll move his money to the bank.
But if he has some problems with bank - the better way is that you said - deposit and withdraw using Paypal.
There are some countries that do not support PayPal.
I have used bet365 very well before too, you can deposit with credit card or master card, but unable to withdraw using the same credit card or master card. But there are some deposit methods on bet365 that only the deposit method is the only way you can also withdraw. It a depends on how it is on bet365.
The best way for people that have low withdrawal option is wire transfer.
I recommended to use PayPal if you have some restrictions with gambling. In such situation i don`t think that using bank transfer is a good idea.
The same time, if we look at the table, @Daltonik attached, we can see that there is no problem with withdraw using Visa or MasterCard. And you can do wire transfer. But i don`t think that it would be easier than using credit cards.
