How long does it take to learn bitcoin?

First hearing about bitcoin in 2013, I had to do a lot of research which mainly consisted of wikipedia and bitcoin.it along with as many various youtube videos and other crypto related websites and videos from all over the web, and even in-person meetups.

Finally on Feb 16, 2015 Prinston University released a video with Ed Felton Lecture 1 — Intro to Crypto and Cryptocurrencies.

This is amazing, as far as I can tell it is the first of its kind course offered by a well known university and I can't wait to see the subsequent videos. I decided that I will review and understand what's in these videos in depth and since there are many sections in each video I used the youtube timemarks and links so anyone can reference the topics. Find those posts here.

Let me your thoughts on bitcoin and on the learning of these technologies in the comments.

Thanks for visiting.
