Be aware that even Zachodni WBK changed their TOS. Paragraph 13 now says that any use of the card in connection with virtual money (and they explicitly mention Bitcoin) will get your card blocked. It seems that known exchanges like Bitstamp, Btc-e and Kraken are already black-listed and withdrawing from them will get your card blocked.
Well said, that's why I stay away from mBank - I don't want to put my Customers into risk of losing the money.
That's true WBK blocked some countries, but mainly only some of the 3rd world (you can find exactly which ones in my thread).
True, WBK doesn't allow virtual currencies anymore but I know some of exchanges that are still working (not blacklisted). I've tested them by myself several times and they haven't blocked the card.
Also, it seems that Paypal has banned mBank cards, while WBK cards are working great (at least PLN cards). Currently I'm testing other currencies.
Kind Regards,
