I also did it some time ago where I showed two of my classmates my bitcoin wallet then the amount inside it as well as its price in my local currency and as usual they get curious too and asked how is it considered as a money or how it can used to buy some stuffs and how can I convert it into cash . I explained to them how can bitcoin works and how it can be used as a medium of exchange or payment, why it has a value and lastly how am I earning it .
I will share a liitle bit information about bitcoin first then if i saw him that he had an curiosity and eagerness to know more and eagerness also to earn money. And thats a good thing to share many things about bitcoin. On how can you earn through this forum. I will share the things that i know. Just like joining in a signature campaign.
