Another reason why you don't have to force people into learning bitcoin or investing in bitcoin is that,if you force them, it will look as if bitcoin is a scam because, you are over doing it and they will be reluctant. Lastly, if you want to teach or introduce bitcoin to someone, make sure that you tell him more of the risky side and don't just tell him about the benefits,so that it will be the person choice to invest in bitcoin or not.
Actually, The people would know themselves without being told it, because the news always spreading up everywhere, and every time. I always see the news about Bitcoin on my local tv and the presenter is always talking much how to buy and the right way to invest. So, if they are economical and know how to use the money, they will research itself what is bitcoin. if they know themselves, no one to blame him if they lost on trading or investment. Bitcoin is global, do not be like you own itself by pressing someone to buy it.
