1. How many people understanding the banking system as it exists today?  I think the banking system is more complicated than Bitcoin by far. 

2. How many people really understand the internet?  Yet, the internet is huge. 

3. Bitcoin is just a baby, similar to the internet in 1995.  In time it'll be much easier to use, safer, and stronger.  Felix assuming that the Bitcoin of 2016 will be the same as the Bitcoin of 2014 is just as silly as thinking the Bitcoin of 2012 is the same as today.  Since 2012, Bitcoin has come a long way.  Wasn't Gox about the only way to buy and sell Bitcoins back then, now it is super easy.  And there were only a few places that accepted Bitcoin for tangible goods.  Now there are lots of places.
