As much as I dislike Youtube, use it. Don't read the Bitcoin whitepaper quite yet if your completely new to the subject. It'll likely only scare you, or make you think you don't understand it. The thing is, the whitepaper is great to a certain extent, but not for non technical users. So, its much easier to have Bitcoin described or taught to you in layman terms, rather than jargon. While the whitepaper definitely isn't the worst, I'd recommend only reading it once you think you've got a basic understanding of Bitcoin itself. Once you do, it would probably be beneficial to either use Youtube or come here, and find out what each technical term means. A quick search would pretty much sort you out here, since its likely been asked many of times.
