credit cards would be insane. It just seems so strange that a major card company would choose to work with this unknown coin from Ukraine.
This "unknown" coin is one of the best coins of 2017 and could be for the best in 2018. But about card companies and banks, everything depends of who is developers. If it is some kind students from 3-rd world country their product will never be high. But here we have developers who knows bank sector in Europe and in the world. That's why MNX is growing so fast. Just read who is in MNX team and who helped to create this coin.
