I think bitcoin is better than banks because with bitcoin we have full access and control, I do not like to waste time waiting in line so I hope that someday the transaction system is like bitcoin.
Of course, bitcoin has many advantages, but at the moment, we can not give up banks, because it will change the world economy at the root. In any case, at the moment we should rejoice that we can use bitcoin transactions, and the rest are crypto currency.
I think banks will be their forever. If all the people start using bitcoin, bank will also change their services for survival. May be they start using bitcoin and give people the facilities of transaction, transfer and trading. Therefore we cannot exit banks from the system atleast not in the near future. Bitcoin has their own features and benefits.
