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 .
There are weak hands who never buy BTC when the price is low, they always wait until BTC price starts to rise and because of fomo, they become interested at that time. However, i don't think you need to show anyone that you are getting returns from your BTC investment, that is not even a safe approach to take, you can even expose yourself to a $5 wrench attack if you do that, always keep your financial wins to yourself and maybe your family.
