4. Deal with it, not everyone is going to like/understand crypto
You don't have to convince everyone to invest in bitcoin or cryptocurrencies in general. They don't like it? Leave them be. Also, NEVER EVER tell people to invest because the price will "moon". Price increases are NEVER 100% guaranteed.
I agree with you, we can not pleased everyone to like cryptocurrency. Just let it be. If they are curious about bitcoin they will find a way to do it. They will self study, research about it and so on. Just leave them and focus on what you are doing they can not helped you with it. Yes, stop convincing people to invest because if the project will not succeed and they are not earn from it you will be the one who will reprehensible.
