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 .
showing our bitcoin wallet is one the best thing that we can do spread bitcoin in to other. Because by this way we are giving a proof that bitcoin is real. When I did that to my neighbor they get interested on it so I tell them all that i know about bitcoin like how it works and how to earn it.
Yes people are more interested in such activities where it comes to the earnings stuff etc. Well there are many people using the Bitcoin and they all have their own way of marketing for the Bitcoin. It is good basically that everyone reacts to his surroundings and apply an own built strategy for to attract the people and convey them to use the Bitcoin.
