In a parallel thread with the same information users who have used bitcoin cards in the past has stated that they have been charged high than what we spend on exchanges. So this need to be taken off for the increased usage of bitcoin cards as well increased accessibility needs to be provided as most of the bitcoin cards come with limited usage on shopping.
What do you mean by limited usage on shopping? Doesn't it depend on shops and their acceptance of bitcoin? Or you mean the acceptance of cards by online merchants?
