Serious problems with the following sentence:

  It also means that Bitcoin provides a unique digital 
  fingerprint, which allows for anonymous and irreversible 
  transactions.

  ...

  unique digital fingerprint >> anonymous and irreversible transactions

So, Mr. Senator, what your telling me is that unique, readily identifiable, globally visible objects represent the very apparatus that prevents identification? How, precisely does that work?

Because fingerprints have neve been used to identify anybody, and are also totally anonymous!

That's why the police never use them to solve crimes, of course.
