The bold part; no one should ever try to influence in any financial decision as at the end, if it turns out bad, you will be accused of. I have shared about bitcoin among a lot of my friends but they were never interested untill recently when they saw news on Bitcoin here and there. A few of my friends knocked me and started to ask whether they should invest now or not & my answer was same almost for everyone as the price has skyrockted already, "DYOR". However, to my known, one has invested around $33k; I had helped him picking wallets, purchasing his first bitcoin.
Sound advice. If you value your friendship, you shouldn't risk it by trying to influence someone into anything. All friends of mine, have approached me for advice, rather than me trying to push anything on them, because no matter how much you put a disclaimer out there, they will likely hold you responsible, if it was your idea for them to invest.
If we talk about teaching someone and explaining the theoretical part, it is always necessary to offer the necessary materials for reading or viewing. This is where we can properly direct the newbie by showing him the right sites and books that provide competent information. It will be very reckless to direct a newbie to watch YouTube, in which, when the price of bitcoin rises, a lot of garbage appears and confuses a person.
Only after you see that a person is ready, that he has an understanding of the risks that may await him when investing, then you can express your opinion about purchasing cryptocurrencies. And as the next step, move on to practice.
Your conscience will be clear if you are careful about what to do and what not. And the choice should always remain with the owner of the funds who plan to invest.
Also, if you are recommending books I wouldn't suggest recommending it without vetting it yourself. You shouldn't be recommending anything that could potentially be bias either way, or provide misinformation. Especially, when it comes to cryptocurrencies, the amount of factually incorrect statements, and bias even on "reputable" websites is quite significant.
This is my way; never push your ideals, or even ideas on anyone. If they are interested, they will ask how to start. I'm not into the whole business of advertising, and basically being a recruiting agency. I didn't find Bitcoin by being recommended it, I found it because it was in line with my values, and situation.
