I Believe, if we can spread value of BTC, surely people will invest future more than today
It takes time, the population of the world is large so its easy to say but its hard to implement and do such opinions like this.
no one believe anything without reason
Until they see others gaining.
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.
Take note of that, only those who are willing to invest and understand the risk as well. What people are thinking that bitcoin is 0 % risk and they can be rich on an instant after buying.
