Hackers is not the main problem, the main problem is the bank's income will decrease. Bank get income because people use fiat money that created by bank itself, there is a system that makes bank can get advantage from the use of fiat money by citizens. If people use bitcoin then that system will no longer work for them anymore.  So bank will not offer bitcoin deposits.

I think they will have to do it. They won't do it willingly but out of force. Bitcoin is the future of financial transactions. They can try their hardest to surpress it but the power of Bitcoin is unlimited. You can't fight it and if you can't beat it, join it.

This situation may well happen in a few years that the official banks will start accepting bitcoins, but it needs the bitcoin exchange rate to stabilize.

the is coming when bank officials will offer Bitcoin deposit with begging because they know it attracts huge profits. we shall get their soon or soon next.

I think maybe, one day BTC will become stable and predictive so banks can use such opportunities. I'm not sure how fast it can happen.

Maybe or maybe not. No one can predict what will happen with Bitcoin in the future. It could either succeed as a mainstream cryptocurrency for frictionless payments, or it could fail. If it succeeds, then everyone would become interested in owning a piece of the pie. It has been shown that Banks and Governments are interested in Bitcoin's revolutionary technology. Since Bitcoin is considered by many as the successor of Gold, then there could exist a possibility of Banks offering Bitcoin deposits to its customers.

But, there is the concern that if Bitcoin becomes too big to fail, Banks will envy its existence and will try to do anything at their disposal to destroy it. They will see Bitcoin as a real threat to their existence, as it provides borderless payments to everyone around the world without the need to worry about middleman.

All in all, if Bitcoin becomes accepted at Banks worldwide, it'll be huge, as the original cryptocurrency becomes one step closer to mainstream adoption.

I think they might attract investors of this type by saying that their bitcoin will be safe in their hands. We know how banks do well in making money.
I like to deposit my fiat to the bank and they make money with it but if it's bitcoin. I don't think I will take advantage of this service but there is a possibility that it will come and they will target bitcoin investors holders who don't really understand what bitcoin is, being your own bank.

Most likely it will be a common practice in a few years. Just the growth of Bitcoin will not be so rapid. Even now there are already banks that accept deposits in Bitcoin. These banks are located in Switzerland.

Banks in any case will not switch to Bitcoin. One of the advantages of currency is "incognito". So the Bank immediately you can remove. Banks are regulated by the state and without the identification of a person, he simply will not open an account. And no account - no currency.

However banks will not switch to bitcoin only. It can be an advantage to the banks since there are many bitcoin users around the globe. There are some banks who are already accepting bitcoins deposits
