Start in small ways, start with family, friends or even office mates. Be a good example, show them the good things that you got, not just material things, peace of mind, time, financial freedom. Use them to ignite their interest and curiosity as to what brought that change in you and in your life. Then once they already are the ones who want to know, start to share your story and then introduce crypto currency to them. It will be believable because they are seeing the positive changes right before their eyes. Start from their and pass it on.
