The main problem why people do not understand Bitcoin because it is very hard to describe using existing experience (physical money). People failed at first when they tried to explain cars from the perspective of railroads and horses.

We had the Internet of Information, now we're witnessing the birth of the Internet of value. People always freaked out during the shift of monetary system.

Bitcoin is not a currency, payment network or banking system. It is a platform that guarantees certain trust functions. Currency is just an app running on Bitcoin network. Since very old times money has provided trust function and that's why it became one of the first uses for Bitcoin.

Who issued the currency will no longer be relevant, who uses it will become the main factor. Most likely there will me meta-currency which will have the purpose to aggregate the value of all the cryptocurrencies.

Design metaphors are extremely powerful but they can also be extremely dangerous when misapplied (e.g. wallet concept in Bitcoin).

Credit cards are broken by design because the token itself is a secret key. While BTC transaction can be transmitted using completely insecure way (e.g. even smoke signals or carrier pigeons)

The value should not be mistaken for medium (infrastructure) or control over it.

There are smart networks with dumb devices and dumb networks with smart devices. Cryptocurrencies are the latter one. They encourage innovation at the edge. Bitcoin is going to win because it is open in a world of thinkers and innovators.
