Yes it is often not worth the effort. Initially I was so enthused by the concept of Bitcoin that I could not help telling friends and family about it- but very very few of them 'got it'. Have come to the conclusion that Bitcoin is too radical and anti establishment for many people- the problem is they do not understand the inherent inequality and power imbalance that the fiat monetary system is built upon and so they are unable to understand the beauty and need for Bitcoin. So I come to the conclusion that people will 'get' Bitcoin when they deserve to- the fact that they do not yet 'get it' is largely because they do not care enough about equity in the monetary system. Perhaps we can try to educate people to understand how the fiat system is fundamentally unfair and manipulative but I still think most people will struggle to understand and accept that and that Bitcoin presents a real and viable alternative. Most people are sheep.
