Your explanation is not nice for everyone and will be too rookie for some people. If you must talk about bitcoins to someone, Observe the kind of person the person is, so you know the best way to explain bitcoins to them. If you give the explanation that is childish to someone who is mature, they will not be interested, so you always need to understand the exposure of the person you are talking to so you know the best approach for them. To some people, simply referring them to read a book, watch a video or to join this forum is enough for them.
