Bitcoin does not make banks unnecessary.
Bitcoin cannot provide loans.
Bitcoin cannot provide investments.
Bitcoin cannot provide estate security.
Bitcoin has it's place as an option to the intelligent investor. But it will never replace a bank.
yeah, bitcoin will never replace bank, it is impossible, I just see bitcoin is good for international transfer, only international transfer is better than banks' transfer, much faster and anonymous. But the price is volatile, when btc is not volatile, btc may be used as a currency, or alternative, but never the alternatives of banks.
