I'm still holding USD there. Definitively not taking a 5% haircut!
edit: wow, checked again and the advcash fee is 10% now

Thats too much fee.They posted that they plan to lower fee .
I already waited 10-12 days for bitcoin rate to improve but its getting worse... But, I think I should wait more for lower fee.
The fiat withdrawal fees have most likely been raised to 10% in an effort to stop the carry trade from other exchanges exploiting the high crypto price on WEX. 10% is probably not enough. eg. USD/BTC is currently trading about 13% higher on WEX than other exchanges.
