Its a good write I would say. But, you need to change the interface a bit. The text seems kinda a larger than normal and kinda gets annoying to read. And instead of going to direct technical terms/part of the technology, it is better to explain them how to use it and to store it safely. People who are new to crypto currencies might end up thinking that it is a very difficult thing to understand and use.
I thought you want to know about bitcoin because of the title "What is bitcoin? and the technology behind it" but it's an article. I think the title should be Article About Bitcoin and the technology behind it. My thoughts about this thread is that the title is asking and the content is about an article about bitcoin ready to share.
That is why he used the quotation mark on "What is bitcoin?".
