As a newcomer, i shared my ideas with everyone.
For me, it is not really necessary to everyone to find out about bitcoin. It does not matter a lot nowadays because we still have current payment systems.
If these digital currencies becomes the only means of transaction, people will just adapt.
It doesn't matter what time you did know about these digital currencies. Of course exemption to those technologist, investors, and other people who wanted to use and know more and/or make some money with the help of these new era of currencies.
People will just adapt to the new system if time does come.
But it is a big opportunity to enlightened about these cryptocurrencies.
