true really bitcoin do not like fiat, a lot of people using bitcoin that their identities could be private, when you use bitcoin bank certainly identity will be discovered,
But what about the exchanges that require data verification, is it that also make your identity uncovered ?

To say that Bitcoin banks would be useless just because they would provide basically the same options as web wallets do is naive at best. Should Bitcoin banks emerge for real, that would most likely be our regular fiat banks now accepting Bitcoin. The first thing that comes to mind immediately is closing the wide gap between fiat and Bitcoin. They would effectively combine in one place the functionality provided by exchanges (i.e. buying and selling bitcoins for fiat) with that of web wallets (i.e. easy transactions, most likely free of charge altogether)...

And this advantage would come about just through their existence as such

The fact that CoinsBank has the word "bank" in its name doesn't in the least mean that it is a real bank (Bitcoin or otherwise). If we are expecting Bitcoin to become a major currency (which is unlikely to happen, just in case), then banks could accept money (which would be bitcoins) from folks into deposit accounts and issue loans as well as deposit certificates (which could be used as paper money for offline transactions). That's what real banks essentially do, and that's where genuine Bitcoin banks (and not a certain CoinsBank which is in fact just an exchange) would be different from web wallets...

I hope this helps to clarify how such banks could be useful in the future

agree with the bitcoin bank

The idea of the bitcoin bank may not be very appealing for most people here because most people here are not idiots that don't know how to deal and hold their own bitcoin, but outside of internet forums most people are clueless and they will like the idea of other third party managing their money and not having to stress about losing your private keys because you forget the password or something like that, so yes i think there is still a strong niche for that bankster idea on bitcoin.

Well here in my country we do not need bitcoinbanks because we can easily or instantly cash and encash bitcoin.. unlike before that it takes a day or days before we can withdraw or deposit.. so we do not need that bank.. i think the only help of bitcoin bank more people can be trust bitcoi nto use if there is people who are starting a banks for bitcoin that they can think that bitcoin is real..

That's true, some web wallets are just like this, (like coinbase), as they required to send their users their personal information just what all banks is, instead bitcoin can do transaction without this personal information so whats the point why bitcoin bank can be created it simply destroy the anonymity of the coin. 

With the fast pace of technology, we may say now that we don't need it but I guess when the right time comes. We don't have choice when those banks are going to adopt the usage of bitcoin with their system. But as of now we don't need to think about that for that will be a long debate in the congress of a country that will allow that to happen.

Most people are here for profits, not for some ideals like anonymity (which is still subpar, by the way), so, I think, you shouldn't use "we" (just speak for yourself). The purpose you are talking about has been defeated long ago already. Major exchanges (e.g. Bitstamp, Kraken, etc) already have KYC policies implemented, especially if you are going away from Bitcoin and trying to cash out. I guess it is the same with web wallets and their Bitcoin payment cards as well...

In other words, it is six of one and half a dozen of the other
