星巴克等多家大型公司参与加密支付APP测试

Gemini创始人Winklevoss兄弟使用加密货币GUSD在星巴克购买了咖啡,此次购买是通过一款名为Spedn的APP完成的。据报道,Spedn由支付初创公司Flexa开发,支持BTC、ETH、LTC、BCH和GUSD。根据数百名参与测试版的测试人员向福布斯提供的收据证实,加密货币购买是在GameStop、BedBathandBeyond和WholeFoods进行的。Flexa还提供了来自Barnes&Noble、OfficeDepot和Nordstrom的电子邮件,以确认这些商家参与了该项目。Flexa称,现在正式接受加密货币的公司包括Barnes&Noble、BaskinRobbins、BedBath&Beyond、CaribouCoffee和亚马逊旗下的WholeFoods等16个公司。尽管没有就此事进行官宣,但据称星巴克也参与其中。预计到今年年底,将有近100家商店开始通过Spedn应用接受比特币和其他加密货币支付。

前美国国会议员:加密货币挑战了货币体系现状

前美国国会议员和总统候选人RonPaul今日在CoinDesk2019纽约共识大会期间接受采访时表示,众议员BradSherman呼吁禁止在美国购买加密货币是一个可怕的想法,并称他“只是华盛顿的另一个暴徒”。Paul指出,立法者和监管机构特别关注加密货币的原因之一可能是加密货币“挑战了货币体系的现状”。当被问及如果他竞选总统可能会采取的加密货币政策,Paul说他将主张一个轻松的监管机制。
