Of course banks and governments are intimidated by cryptocurrencies. Average people don't really understand at all what happens in an economy. I don't understand that well either, but the way that centralized banks work it pretty messed up. As far as I understand, they create money from nothing and then loan it out and charge a percentage. This causes causes inflation or the devaluation of everybody else's money. I'm sure that banks will figure out some way to benefit from cryptocurrencies, but I have a feeling it might not be so lucrative. Cryptocurrencies seem to be based on transparency. Everybody can be rewarded if they help support the system. This is pretty different from our "traditional" economy.
