If people around you start getting interested in bitcoin because of the recent bullish news but ignore what you told them before. That shows they are quite pragmatic and they need more concrete evidence of what you say. So I think there is no better advice or explanation than evidence, and the best evidence is the results you get from your investment. I mean, as long as you can show them how your financial situation has improved thanks to bitcoin , that's the best advice you can give them. Because if you still can't improve your financial situation , I think no matter what you say, no one will believe what you say .
If I have given someone advice and an explanation about bitcoin and they still don't buy it, and now they are seeing Bitcoin very bullish, I don't think I have any further explanation to give to them. I owe them no further explanation.
For security reasons, you should think about it the other way round: What if they are not really looking for reasons to invest in bitcoin but rather they want to see how financially stable you have become? Out of envy or due to greed, do you know what they can plan against you? I don't think it's right to show someone how Bitcoin has made you stable or what you have achieved. We should also learn how to stay safe while trying to educate someone about Bitcoin; it's not a force to bring anyone in; there is no reward for such. On the other hand,
