Sorry 21th, The Bitcoin Idea Belong to the 20th century

we all know that bitcoin appear on 31 October 2008 by Satoshi Nakamoto after American crisis, bringing a new idea about a digital currency without any central authority control & the possibility to make an anonymous transaction.

but did you know that idea about making a digital currency return to few year earlier before Satoshi did, like Cryptonomicon book publish by Neal Stephenson on November 5, 2002, the other book "Down and out in the Magic Kingdom" which was published almost a year later than “Cryptonomicon,” on December 5, 2003 by Cory Doctorow or Future Imperfect brought out on July 21, 2008 by David D. Friedman, but to get the closest définition to bitcoin you must go back to the 20 Th century, where the American economist and Nobel Prize winner in Economic Sciences Milton Friedman has aptly predicted the rise of digital currencies like Bitcoin in 1999.

Friedman said that a reliable but discreet method of financial transactions will develop on the Internet in the near future.

In an interview conducted by NTU/F in 1999, Friedman said:

The one thing that’s missing, but that will soon be developed, it’s a reliable e-cash. A method where buying on the Internet you can transfer funds from A to B, without A knowing B or B knowing A. The way in which I can take a 20 dollar bill and hand it over to you and there’s no record of where it came from. And you may get that without knowing who I am. That kind of thing will develop on the Internet.
