At first no one came..
After my recommendation.two friends started.
But they felt this as boring so they discontinued.
Try to make some earning by yourself than show off to your friend and then your friend will start interest for it. For the first attempt, can try to treat your classmate or office friend some food because you're using bitcoin instead your own money.
This is a great way to get someone interested in Bitcoin. When I tried to get one of my family members interested in Bitcoin, they wouldn't accept it, even though a few of my other family members have already. But then I used Bitcoin in a real world situation, and now they too use Bitcoin, because they saw how easy and fast Bitcoin really is.
That is what I am currently doing. Most of my friends and family have no idea what bitcoin is. It is just some weird nerd hobby
