If you only show the positive picture of Bitcoin's price and try to hide the downward moments of the market then you are doing even worse. Those people if lose half of their capital during a bull market would never trust Bitcoin investments again.
And I think that's the exact point where the O.P of this thread is driving to, that is, those who only speak of the good side of Bitcoin and not the negative sides so as to create balance in whoever pick interest in it and decide to invest in it. Because I have a friend of mind who approach me last week telling me of his interest to invest the money he intend to use for his traditional marriage in Bitcoin rather than leaving in bank, that like how much profit can he get for investing $500 after 2 months time. And I just have to be plain to him that Bitcoin is not like a Ponzi scheme where you could invest "X" amount of dollar today and except to earn a reward or profit of "Y" amount in either weekly or monthly, which in most cases likely to end up being a scam. But I was able to tell him that Bitcoin is a volatile digital currency whose price value likely to rise or fall, depending on the demand & supply, and a good option for a long term investment & other benefits, but how much he could make in 2 months time is what I dont know, as he could likely make profit or lose. And since then I'm yet to hear his final decision.
When giving advice to someone, all possibilities should be mentioned. This behavior also shows how much we value that person. It's easy to say, invest and you will definitely win. But what if it doesn't? We can upset that person and cause them to lose money on the investment.
When someone who wants to invest but has no knowledge asks us a question, we should first explain the risks. You have given your friend good advice. Tell him that the final decision is still his.
As the OP said, I think it's a big mistake to teach Bitcoin by force. For someone who is not interested in Bitcoin, trying too hard can have negative consequences. If they invest and lose, Bitcoin becomes something to fear for them.
