Now i think its not a good thing to buy it so for me bitcoin debit card is useless because im only earning here, im only small time earning so i dont think that bitcoin debit card is a good thing to buy. But In future its good thing to buy it. Many bitcoin user will buy it because they want use their earning directly to the shop. But for me its good because in future im.earning big amount of bitcoin so i need it to my shopping time.
