Re: How will you teach bitcoin if someone does want to know coming from you?
I started simply with Googling and reading everything about bitcoins and crypto currency in general. But this forum definitely helped a lot and it's always updated so it's almost impossible to miss any kind of important news and information. So I'd recommend anybody to start with some basic information and then proceed to register here. 
That will be a good way for new people who wants to get involved in cryptocurrency.He should be able to learn by himself and just to ask for the question. If he still confuses about what he learns, then he can ask with his friends, or he can ask in here.
Learning basics information is a must thing that every new people should do, and they need to search in many places if they want to know more about cryptocurrency or bitcoin.
That will not just stop for some period, but you will need to learn in every day and search for more new information to improve your knowledge in cryptocurrency.
