Most people come to me and ask questions about bitcoin and the finance issues, mostly people that want to invest, therefore they need some kind of strategy involving understand what they have in their hands, how can they learn and the classic cash-out.
So, as OP said use words like decentralization or permissionless is not worth it...at that point of the conversation, later yes, maybe, not now.
However, how to convince nocoiners? Most people just want to know two things:
  • Does bitcoin have value?
  • How can they make money?
My strategy is simple:
  1. Get a wallet
  2. Explain how to DCA with bitcoin. Save, no invest.
  3. Usally at this point and if they bought their first satoshis, they'll learn more about other projects, most of them, pure crap. So..
  4. I show them how this PoW alterative works and how most of them are doomed to fail misserably and make the cautious annoucement that the only thing now can make is to accumulate satoshis.
At this point, most people, blinded by greed, will open a Binance/Kraken/Fav CeFi to purchase some dog coins, monkey coins among others. You can't do nothing, just a friendly reminder about what the f**k they did it. Doing this is the reason we're maxis, so no worries.
Finally, the (alterative) final stage: most nocoiners will not pass the second step, so to them -and you OP- I leave this known quote:
If you don't believe me or don't get it, I don't have time to try to convince you, sorry. --Satoshi Nakamoto
