60秒科学：Cyber Currencies Get Boost from High-Profile Endorsements
60秒科学节目（SSS）是科学美国人网站的一套广播栏目，英文名称：Scientific American – 60 Second Science,节目内容以科学报道为主，节目仅一分钟的时间，主要对当今的科学技术新发展作以简明、通俗的介绍，对于科学的发展如何影响人们的生活环境、健康状况及科学技术，提供了大量简明易懂的阐释。
Virtual currency was on the ropes earlier this year. Bitcoin, the preeminent peer-to-peer online payment system, saw its value slashed by more than half after its largest exchange was hacked and shut down. Yet the fortunes of cryptocurrency have recently rebounded.
Apple used to block programs from its App Store that managed or otherwise dealt in bitcoin and its ilk. Now, though, Apple will allow iOS developers to support the use of certain cyber coinage. Apple has yet to say which of the dozens of cyber currencies out there it will now honor.
Meanwhile, satellite TV provider Dish Network will soon start letting its 14 million household subscribers pay their monthly bills using bitcoin. And rapper 50 Cent is accepting bitcoin as payment for his latest album. By the way, at this moment’s exchange rate, 50 Cent would also be known as 0.00075 Bitcoin. Not as catchy.
Such high-profile endorsements should help bring cyber tokens closer to the mainstream, even though there’s a risk that they’ll go down in value once you buy them. Still, U.S. consumers might be open to the idea. They’ve been hooked on a virtual currency for decades. It’s called credit cards.
