I have not tried Minexpay card but today many new ICO and tokens introduce their cards just to attract their ICO and users.
If the cards were so important for the crypto currencies, bitcoin would had the first digital card but there exists nothing. I never understand why crypto needs a digital card ?
You do not understand this, because probably or you have nothing to withdraw from your counts in fiat, or you do not understand millions of people in other countries in which it is forbidden to directly receive money from cryptocurrency into accounts.
