I first read it on 2017. At first I was into it because of the utility and use cases. At the time I was really more interested in Ethereum and Dash. But eventually I thought "why the hell not" and got to https://bitcoin.org/bitcoin.pdf and was surprised that it was basically just 9 pages and was further surprised that I could understand most of it. Te reason I didn't read it was because I though it'd be full of cryptography and programming. It's not the tech that made Bitcoin amazing. It was the idea and the new ground it broke.
