Bitcoin can't replace banking. I guess its just some sort of investing or else an online currency. Many people rely on their banks and even have debts, how come Bitcoin can make Banks disappear.

If more and more peoples invest into the Bitcoins, then it will lost some customers who save money in the bank or invest on the Stock market (other markets) through the Bank. It actually make the EU and US stock market not so exciting as well.
Btw. I am regret that I still keep some money in the bank and stock market, not transfer into BTC 2 days ago. Or maybe should buy some new encryptions like Deep Onions. 

I doubt bitcoins can beat fiats and the banks that hold them because of one thing: bitcoins and fiat money are two completely different things. One can never beat the other and vice versa. But for me, it reakky depends on the masses' reaction on whether or not bitcoins as a world wide currency, will help ALL of the people, whether poor or rich.

Yes i wil sure after 10 years bitcoin will replace bank because bitcoin is more power and more fast than bank so this is the new era we should need to earn bitcoin now until we regret someday rean a lot now and hold it.

Certainly can make financial institutions vanish, but not now considering that the govt are nonetheless using fiat, which is based on a big large lie.

As long as bitcoin is not legalized it will not make banks or financial institutions disappear. I'm sure banks and governments will continue to work together and campaign for the fight against bitcoin.

The answer to these question might be a yes and a no. Maybe yes, because bitcoin is a good way to store your money and it is very secure like banks. Bitcoin is very comfortable to use because you can access it thru the internet and if you have an application that lets you keep your bitcoin and you can convert it to cash in an easy way. If some of the restaurants or places that accepts bitcoin as payment, that would be very useful.
The other answer is maybe no, because banks are still useful these days. You can cash out your bitcoin via banks and that is very comfortable for those who have bank accounts. Banks are also useful for those who are not yet knowledgeable about bitcoin.

Banks are important in this world because they are giving us the service to safeguard our money, though it does not earn a lot of interest
but I still believe when it comes to safety it's more safer that putting our money in our online wallet.
As long as you have a clean record, your money will not be lost because the government will protect it with their insurance.

I'm not sure about this, there are many predictions that bitcoin will replace the bank, however the limitations and inadequacies that bitcoin encounters with me are that this is hard to do.

The presence of bitcoin certainly brings a huge impact in the transaction system, it can not be denied that the bitcoin transactions are getting bigger making banks less value of transactions. even so, I'm not sure that the presence of bitcoin can make banks disappear.
