Bitcoin Information

To help other more easily understand the complex world of cryptocurrencies I wrote to the local community college and suggested they teach a course on it.
To teach that class at my local community college on bitcoin and cryptocurrency, I wrote down all the info I thought I knew about the subject then looked up every point.
The end result is a large collection of information on and about Bitcoin and cryptocurrencies that I want to share with others. The information is divided into subjects below, feel free to use or share. This information was relevant in early 2016 and many things have happened since then.
