Well, as much as i admire your self sense of learning, i doubt it is applicable to the general public. Equating bitcoin as a currency is quite easy to understand specially if we simply talk about purchase and payments (although it still holds a substantial amount of explanation as to how bitcoin gained its value).

But dwelling deeper on investing and trading and its economy as a whole could never be learned easily. In fact, ask a layman to sign up on an exchange or better yet, simply create a bitcoin wallet on his own might prove to be a horrendous process without any guidance.

Emails are easier to start with. But, allow me to stress this, bitcoin can be learned, perhaps not as easy, but could definitely be learned and understood.
