对没有信用卡、或不想用手里那张卡的人来说，Bitcoin 会相当方便——不想让配偶在账单上看到、不信任把卡号交给「色情业者」、或者害怕自动续费的人。
Bitcoin would be convenient for people who don't have a credit card or don't want to use the cards they have, either don't want the spouse to see it on the bill or don't trust giving their number to "porn guys", or afraid of recurring billing.
