Hi developers and project managers. I read about your project, the idea is very interesting, but I think that making your own plastic card will be very problematic. My opinion is that - you can make a platform where you can buy your coin for any currency of the world by paying through the card, and then sell for the currency you need. You can also make money on any card or account. Plus, I would make it possible to withdraw your coins to the stock exchanges, thereby you will have the most demanded way of withdrawing or entering money into the crypto currency, taking a very large market from the exchanges.
I would also add support for a mobile wallet, it will make it easier to work with your project and attract a lot of investors, because almost everyone has mobile phones and it is very convenient when one application can quickly exchange currency or withdraw money from exchanges. If my ideas were useful to you, you can thank me with a small amount of gift steaks
