Iam not sure that Boris understands real consequences of giving non-branded payment cards(basically you use other company cards as yours own) which is strictly forbidden by VISA and Mastercard regulations.
There is no question that these irregular non-branded cards will be cancelled ,only how fast it will happen. Repercussions for customers( and Minex too) will be devastating.
I understand that Minex is under enormous pressure to give some positive results as soon as possible,but this is completely wrong way which will push things only further down.
These companies who followed regulations and spent many months to issue branded cards are not bunch of fools.Cant build business on constant avoiding necessary regulations and laws.Instead of positive developpment you will receive constant backfire until whole project will be in ruins and nobody will believe you any more.
Man, if you're right, and I'm not saying you are, it would mean both Bittrex and Bitstamp involved in topping up my gold Mastercard plastic issued by Paribas have been not existed. They are alive as well as BNP itself.

All mechanics of MNX card is inside of chain2pay which is part of Minexpay (their system in fact is even more complicated and is hidden from peeping) so only fiat is exposed to both bank and Visa/Mastercard. There's no reason to be nervous on this matter.
