Personally, I'm not a fan of motivating people with NGU. For one, I don't want them to blame me if number go down after they buy.

My approach depends on the situation. If I have like 10-15 minutes, my goal is to tell them what Bitcoin is, without trying to get them to buy it. It's a decentralized ledger book of transactions. That's it. But the bigger question is why we need it.

If I have only a few minutes, I'll usually just say something like, "I'm a big believer in Bitcoin. I read the white paper, it's not a scam it's the real deal." And leave it at that. If they want, they can ask more questions but I'm not going to say more unless asked to.

In general, my approach isn't really to convince people to actually buy bitcoin but just to help them understand what it is and why I believe in it.
