you can just search google "bank threaten by bitcoin" you will see the result.
this is example of one, if you cant use google http://www.coindesk.com/british-banking-association-bitcoin-is-a-real-threat-to-banks/
FYI Coindesk is just made for article not a valid news source.
Lazy to read the link since Im not used to read articles from coindesk. About the bank threaten by bitcoin that is an old story but definitely not a big deal as for me.
