Bitcoin is a physical network, a protocol and a blockchain.  It is all the better for not being part of an antiquated and corrupt banking system where private companies have a licence to print money from nothing and only hold 1% of the funds as fractional reserve. 

We've built a better system which does not require placing trust in private companies who can become insolvent and wipe out any money you may have deposited.  Money which, once you deposit it, no longer belongs to you in the eyes of the law.  Anything you deposit becomes the property of the bank.  The balance you think you hold is nothing more than an IOU.
