The really sad part is when people are asking when we will have a Bitcoin Bank. The correct and the best anwer would be - hopefully never.
Bitcoin was created to battle banks, as they are economic parasites. Average Joe is not even able to imagine how much he is being exploited by big corporations and banks.
Banks are not here to help you, they are here to give you a calendar with a big sign 'Sucker" written on it, because you will be paying banks interest for your whole life.
This is very true. What is the fundamental purpose of banking, and how did banks get started?
One major purpose was to protect you from theft. Thieves could steal your gold and silver, but they could never change the information that you had this much money in an account. Goldsmith banks were born because goldsmiths knew how to protect precious metals, and used that expertise to offer to safeguard people's money.
Of course, once banks got hold of your money, they had the incentives to commit a wholly different kind of theft, in the next few centuries!
Since Bitcoin runs a distributed software protocol to maintain account information, it replaces this major function of banks.
(Although, we have to admit, Bitcoin doesn't address another key function of banks, i.e. to match savers with investments, although it does help make capital markets fundamentally healthier, if it ever manages to take the power of money creation from central banks and governments.)
