I Believe, if we can spread value of BTC, surely people will invest future more than today, no one believe anything without reason, therefore we must explain for people who are willing to invest about BTC, If some one brought a bitcoin in 2010, how much money they can earn within few years, that is the message we should give for society.
Bitcoin price today is far more different than before and if people buy today, they won't earn much profit from it since the pricing gap is too far from the price on 2010. All we could do today is to share some of the insight on why Bitcoin is better for investment and the other altcoins too. Investing in crypto nowadays is better than the real state property but the risk more compare to the real state property.
Investment is not a good term especially when introducing bitcoin for those newbies in the word of cryptocurrency. Of course "they will expect on it" and much worst thinking, they will not wait for that "future" as they want to see some good returns right away.
A typical move from every newbie and all they want is a quick-rich-scheme without understanding the risk.
