You are yet to invest in bitcoin, so how do you explain to people how it is purchased, security and why it save to use than fiat. All these can be preached or thought to someone when you have a personal experience. So you first need to invest before spreading its adoption. Let it start with you.
Then you could go on and preach to them about the experience you have gotten from it.
Just want to add with this reply to OP post, if you preach with less information you wont be able to convince them to invest or to dip their hand's on bitcoin, also you could be labeled scammer, and people this days are very alert, since there are lots of people spreading fake information,
OP needs to learn first, or find a person that is well informed with bitcoin, or already in the industry for a long time, unlike him, that will be more acceptable to those who will see or hear from them.
