Well if I had one I would use it do pay digital stuff that doesn’t accept bitcoin , mainly domain and hosting but also to buy stuff online like steam cards and psn plus that I could find some other middleman who takes a cut to get me the card , this way I won’t have to use a middleman for my online business and just simply use this card to do my purchases , nothing major like thousands of coins , just maybe couple subscriptions every month , thats all.
