I understand the sentiment, but what is there that's hard to explain about Bitcoin? Bitcoin is just a form of digital money. Seriously, for the average user, that's all it is.
We already have Bitcoin wallets, which are the equivalent to your personal bank account. Let's imagine for a second that we also have Bitcoin cards you can use to spend Bitcoin in shops. What difference is there between that and a credit card or debit card? For the end user, very little.
Perhaps the issue isn't so much that Bitcoin is hard to understand, but that money as a concept is hard to understand, or at least it's not immediately obvious how it functions. I'd say the main thing to understand about money is that it is just numbers, but we associate value with those numbers, and in order for us to associate value with those numbers we have to assume others will also do the sane. It is this collective agreement which gives value to money, nothing more. So, with regards to Bitcoin, do you think it will continue to be a valid medium of exchange, and do you think more people will also think this way?
