Dr. Craig mentioned bitcoin is pesudonymous but not anonymous, here I searched for the difference between these two words, here they are:
Anonymity means that someones identity is completely unknown. Any statements or writings made by an anonymous person can not be associated with the individual who actually made them. Indeed, if at some future time the identity of said person becomes known, they can no longer be called anonymous.
Pseudonymous merely means you are not using your real, legal name to identify yourself. While it's possible to be anonymous while using a pseudonym, and many people use pseuodnyms for that purpose, they are not necessarily the same. As a simple example, consider any of the dozens of authors that write under pen names: Mark Twain is a pseudonym for Samuel Clemens, but no one would consider Mark Twain "anonymous". Many authors, actors, or musicians use pseudonyms, and continue to use them, long after their identity has become public knowledge.
簡言之，anonymous是匿名，身份隱匿的，而pseudonymous只是使用假名的。
在Bitcoin中，只是可以pesudonymous而用戶其實無法做到anonymous，因為每一筆轉(zhuǎn)賬交易都是traceable的，有跡可循的。
而這也是比特幣最初設(shè)計的目的所在，并非是要做非法交易，地下黑市的交易貨幣，而是要成為一個統(tǒng)一而方便的線上支付體系，減少或降低各國政府發(fā)行貨幣背后帶來的政府信用危機問題。
CSW正在為他的理想戰(zhàn)斗，從長期看，這是造福后世子孫，避免布雷頓森林體系坍塌，避免美元霸權(quán)，也避免一些濫發(fā)貨幣帶來的金融危機，畢竟比特幣誕生于2008年金融海嘯那個多事之秋。
不過這可能延伸了這樣一個問題，如果今后將錢包的KYC普及之后，實際上所有的account都是可以控制的。
