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.
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.
Look at those 2017 peeps who just put money on bitcoin without understanding the risks. They think they can grab lots of returns back them because they saw others experienced that. They are now finally broke because they forced to dump at much lower prices. They didn't realized back then that bitcoin price is volatile so they only used to see an uptrend.
Let those people who are not familiar in bitcoin know it by their own without giving them just a positive thoughts. It's way more better than to setup their minds that bitcoin will only goes up.
