Well, firstly there are countries where cryptocurrencies are allowed at the official level and in such countries it is possible to use a card with cryptocurrency. And secondly, these are plans for the future.
Cryptocurrency is recognized in several countries. Ok. But please provide an example of using bank cards for payments for cryptocurrency.
Future plans. Issue of cards was scheduled for the Q1 of 2019. It's very soon. I do not think that during this time the legislation will change significantly.
I think that we will use the first OPTHERIUM bank card to cash out earnings from the cryptocurrency market. It will be enough with the help of exchangers to exchange cryptocurrency for the desired type of Fiat.
