It was more than six years ago when it all started and it' still worth reading and remembering.
To those who are interested to know more about it, I STRONGLY Advise that you read “Bitcoin and the Future of Money” and watch the film “The Rise and Rise of Bitcoin”. This will give you new doors in technology.
There's also a good video at Khan Academy about bitcoin.
