Last week I managed to convince a classmate of mine to sell his rare collection of comics to me, in return of 0.5 btc. haha
I have never been successful in trying to get people into Bitcoin in real life, most of them are scared the price will keep getting down, theres not much i can do about that, I have explained them why is it a good idea to at least own 1 BTC if possible, everyone says im crazy.
It takes some time and effort to explain bitcoin to a total newbie.
I am sure they will be thanking you profusely in a few years from now.
