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.
Well that just entirely depends upon the popularity of bitcoin . What are its prices and how volatile it gets .
Also it depends up on the regulations that are to be set by their governments in order to operate bitcoin and other crypto currencies
freely . Blockchain is the future.
