I think that the main problem is that most people don't understand how money itself works. Most people don't understand how Dollars or Euro work that they use every day - if they understood how fiat money works, they would no longer use it. How can we expect them to understand BitCoin?

I composed a beginner's guide explaining Bitcoin and the technology behind it. But first one has to explain money itself, otherwise they don't get it.

I also just wrote an article here on Steemit a few hours ago showing what happened in Greece not too long ago, and how BitCoin kept working when fiat failed:

Greece as an Example for the Power of BitCoin

Here people could clearly notice the difference between the Euro and BitCoin: While the Euro couldn't be accessed, and was being partially seized by the government, BitCoin was working fine. Welcome to the future...
