im doing payments almost every day with mistertango card! it works all the time! the only problem for me is that 0.0025BTC fee for load the card!

Other cards like epayments have almost no fee at all! for load the card with 100€ just send 101.50€... thats a good fee!

But for thoose who work with bigger number than i am, mistertango is rock solid with his WireCard card issuer!! I beleive its here to stay!
