It is my lesson learned that in convincing people about Bitcoin you should not focus in the future. They will not be convinced about it. They are thinking about risk and what will happen to their money. Instead of your predictions which are not a guarantee nor even accurate, focus in the past. Let them see how Bitcoin is transforming into a billion dollar technology from a simple attempt to contribute to a little to change the world. Let them see how the $9,500 Bitcoin started from $0.00000.
So you're talking a brief history if bitcoin from zero to thousands, and now bouncing at $9K and above. In line to the scenario of convincing people, I guess it not important to exert an effort proving the importance of bitcoin for them, because it was just a waste of time. We need to treasure every moment for very important things, but for those non sense people who can't even listen for 1 minute, don't waste your time about it. Time will tell, and I think history prevails the truth over the latest price nowadays which could be more potential to reach a much profitable value in the near future.
You can actually roughly gauge whether a person is really interested or not. If it looks that he is not interested about the technology, try to start from where money is the main thing. You have abundant proofs to show to him that Bitcoin is indeed growing in value. He will become interested with it. And little by little you will insert an information or two about the features of Bitcoin. For sure, if you get his attention by showing signs of earning, he will also raise a few questions about the basics of Bitcoin.
