This year, Bitcoin may become mainstream almost as fast as Gangnam Style.
Interesting comparison.
Well, in my defense - Gangnam Style is also an "Internet thing" just like Bitcoin. And just like Bitcoin it came out of nowhere, nobody expected it and it drastically changed the world (world of popculture in Gangnam's case).
Gangnam style is kind of a revolutionary thing just like Bitcoin - it shows an important thing: that
simply anobody today can become famous, start a revolution using Internet and change the world in a relatively short time (before the internet era such changes would take decades or even generations).
Both Gangnam style and Bitcoin show that we live in truly remarkable times when
just anything can happen tomorrow, growing at exponential speed.
(I am serious, this is not a joke)
