Most of the common people think that bitcoin is used only by hackers and criminals,even one of my friend said that it is used by hackers when I am telling about crypto currency to him.Later I explained what is bitcoin and other crypto currencies but still he confused,he can only get what is bitcoin when he research about himself.
In this situation how can we explain that what is real bitcoin?
In my opinion this is a good opportunity for you to introduce bitcoin to him slowly. You can search for example in various forums to choose which you think is the easiest for him to digest so he will easily understand what bitcoin is like and how bitcoin plays a role in the world of currency
