I think it may be bank and bitcoin would work together and be fruitful together.Banks in would disappear in the way that they wouldn't function as they do now. But this is only the case if bitcoin becomes a widely accepted currency, and we see worldwide adoption. If a currency still keeps fiat as it's primary currency, then it would need banks. It may work together as one,bitcoin and the bank.

This can happen but no one can tell if when. But banks and bitcoin can work together for now. In the future the fittest will stay.

Unless Bitcoin become an asset instead of become a payment method, I think the banking system and the Bitcoin system will never have chance to cooperate. You knew the Bitcoin function are helping many business evade tax and the government always want to kill it, but if they kill Bitcoin, the Bitcoin user will use it for private transaction and that future will be worse than currently.

bitcoin cant make bank gone.
bank have other the advantages that dont have in bitcoin. and we need bank to save our money
we take profit in bitcoin, and bank get profit from us. they are connected.

- Yeah, bitcoin will not be able to replace the bank or make the bank disappear because first the government does not accept that happening, they can not allow a virtual currency that they can not manage, replace their bank. In addition, bitcoin is not so popular, even in the future if bitcoin becomes popular, many people still will not trust the bitcoin, they only believe in cash, and want to convert bitcoin into cash, we need bank, bitcoin just helps the bank to have more improvement and development in the future, it can not make the bank disappear, Bitcoin needs banks

Although Cryptocurrency has many advantages, I don't think Bitcoin can make Banks disappear. Because, Banks have many important roles in the economy, a payment intermediary, a lender, a tool for adjusting the economic policy of the government...

Of course, bitcoins have a significant advantage over banks, but this will not lead to war!

Ability to bypass any sanctions

Despite the high volatility due to the free market, fluctuations in the rate of the Crypto currency may be much less than the fall in the exchange rates of national currencies in the event of political instability in the state, or even a declaration of default. There is no dependence on central banks, local and not only laws, religion, politicians and other attempts to intervene and limit your operations. Including, with the help of sanctions.

I think banks will never disappear, we all know that banks are government-backed institutions, banks are guaranteed by law, although bitcoin transactions are bigger than banks but I'm sure banks will not accept bitcoin.

Bitcoin can not make banks to disappear, it will only make the banks to diversify. The banking sector have been in existence for many years now, their operations are not only approved by the Government but also approved by the members of the body. The banks have a regulating body called the central banks, so the banks have already gotten a solid foundation so talking of disappearing as  a result of an Emerging Bitcoin which though is gaining ground in many counties of the world, but yet to be accepted in some countries,even when accepted by all the countries, bank may key into the Bitcoin Business as well.

Bitcoin can compete with the world bank as more and more people use it as a medium for transactions all over the world. Bitcoin is not a threat for banks for they are different but have some similarities. Bank owners and investors won't allow their banks to be bankrupt and once bitcoin has overcome all the means of transactions, I bet they will start to accept bitcoins in order to keep up with the demands of the people. I don't think banks will disappear because the government relies on it to improve the economy and once bitcoin overcomes banks, they will start to ban it.
