Hi, friend
Don't take what I tell you as the truth.
But I have understood from colleagues who have written in the forum that although you can deposit with a credit card, to withdraw you must do it by bank transfer, or neteller, or
paypal or another electronic wallet.
But as I say, do not take it as the absolute truth.
As for the PS withdrawal amount, I don't know, I'm being honest with you there.
It could be that you have a minimum of US$100. In truth, it would not be bad, because for example if you deposit and on top of that you receive the welcome bonus for US$30 dollars and you add US$50 dollars in total, everything would be very easy you would earn $20 without playing just by depositing.
It may be so.
greetings friend
