Recently my available balance is changed from USD to Pound. Is there any option to change this back to USD or this is a bug?
Might be a bug. You can either contact customer service OR when you do go to withdraw your funds, I know for me, it will put up a screen of how much is transferred and what currency it is going to be in. I think there is a drop down on that screen to change the currency. But, I think I would contact customer service just to be sure it gets changed, as this is too important to mess up.
EDIT: OK, I just looked, and noticed this: go to your DASHBOARD - scroll ALL the way DOWN and in the RIGHT LOWER corner of the page, you will see “CURRENCY” and a drop down menu will pop up which will allow you to change it back to USD!
Oh thanks so much I was about to contact CS but now back to USD!
Glad it worked out for you!
