never i think.
bank have other advantages that very usefull than bitcoin.
for longfterm invest bank is better than bitcoin, and you can ask money for much in short time if you any accident that make you need money.

I don't think banks will ever disappear. Banks are not just a place with bank accounts in which people store their money, they are a center that provides different services such as investment and corporate banking, insurance, money market trading , commodity trading etc. Bitcoin alone doesn't do that. Some crypto-projects are being developed to create legal contracts (Notary), replace real estate agents (Atlant) or loan money (Salt) but I'm sure that instead of disappearing, banks would only start working with blockchain technology themselves and have to adjust. Some banks have existed since 1760 and don't see why they'd fight the current and let themselves drown.

 banks also has huge roll to build economy so its not possible to say banks will disappear  but in future there strategy of can change a lot they will change them self as economy change and make there services according to new demands of society but they cannot demolish fully effect  will be there on there monopoly

It may be because we now see how powerful the power of bitcoins is. And it can change the state of our lives. How much more if bitcoins change the world the money used. So I believe that bitcoins can remove the banks or banks accept the bitcoins and become part of it. There are many concepts and the only thing we can do is contribute our ability so that these words are realized

I partially agree. The idea of Bitcoin is that we are our own banks. I know that not everyone is going to buy a hardware wallets or use a software one but banks won't earn much. They won't be able to earn money on transaction fees and exchanges rates. Their only earnings will be from loans which they will probably offer if Bitcoin would replace fiat.

I doubt that, they will coexist and at the end of the day i predict banks to store BTC and give us cash if needed with low fees

I don't think so. In the future when cryptocurrencies will become more popular, banks will have rebrand. Maybe what we call a web wallet today will be renamed to a CryptoBank? They would offer storing, interest and legal loans. I can't think of any other functions. No need to use real cash = no need to maintain ATMs.

I never think that Bitcoin can make Banking institutions vanish at least in the near futureBut i consider a lot more people will depart banking services as Bitcoin's developing up everyday

banks may adopt the blockchain technology and create private chains, but I don't think they'll be gone until the whole concept of money is gone
