Bitcoins have gained too much popularity recently and also USA is one of top countries in terms of number of bitcoin users.
Seeing interest of people in bitcoins, a new bitcoin visa card has been introduced by the government, the best thing about it is that it just works like a debit card of your bank account.. Which you can use as payment at retail shops. This makes you make transactions in those areas where you have poor connectivity but you want to use bitcoins for paying.  This is certainly appreciable and welcomable.
