Okay, so a relative of mine who has never heard of Bitcoin in her life was asking me exactly how it worked. I tried explaining, but I'm not entirely sure she got it (or she was just refusing to comprehend what I was saying -- she does that sometimes). I suppose I could show her a few of the same videos I watched when I first heard about Bitcoin, but I'm not even sure she'd even really watch them. Any tips, guys?
Install a wallet for her, let her try to receive and send coins
That way is the most easy to understand it. She would understand a little bit about bitcoin from that, just enough to send/receive. If she is interested she will look up all the technical specifications on the web: decentralized networks, cryptocurrency etc. If she wants to know more you could show her the paper, videos etc;
