cryptocurrency is the most volatile thing that i ever see.
i dont think banks will accept deposit of bitcoin because its value can change anytime at huge difference.

The current banking system most likely sees cryptocurrencies as their competition for several reasons which is why we have seen some negative comments from Jamie Dimon and other bank executives.

However, at some point, I think banks will have to adapt to cryptocurrencies and incorporate that into their regular banking activities if they want to survive.

I see this happening from the reverse direction with Coinbase. At first Coinbase only let you use you bank account to purchase Bitcoins. Now they are letting customers hold US dollars in their Coinbase accounts.

I think (some) banks will accept crypto deposits in the future.

I know the dutch bank Rabobank is investigating a new prodcut called Rabobit.
If this goes live, you can deposit BTC\crypto by the Rabobank.
Not sure if that is something to like...

Some financial organization already did it. The Tokyo-based digital currency exchange start offering bitcoin fixed-term deposit accounts to its users.

Only few countries would allow if they decide to do it else I think rest of countries would not allow it as they still have not even decided yet whether they have to allow or ban the crypto currency thus making it more difficult for banks that can accept it.

It's clear that banks or any company will never offer deposits with positive interest rate IN FIAT. For example you lend 1 bitcoin to bank at price $9300 and they will return $9800 after one year no matter what is the price of bitcoin after one year. This is simply too risky for them. But the real question is, are there any companies that offer deposits without conversion - so you lend them 1 bitcoin and receive 1.05 bitcoins after one year. Here the risk is not on their side but on your side. Maybe bitcoin will be worth only half the value after one year, but you will still get only 1.05 bitcoins. Where does the bank get those 0.05 BTC? They get it from people who take credit in bitcoins and return more bitcoins to the bank than they borrowed.

they no choice if they avoid crypto they will be left behind if very person use  digital wallet so I think they making a move to find ways to collided with BTc and the fact that banks and  government can't stop the popularity of crypto.

Once banks finally realize that instead of fighting against crypto, they can join this innovative market and make big bucks, surrender to crypto trading, and allow their clients to carry out virtual currency transactions.
This will be a superb cryptos victory

Do you even know why bitcoin is being preferred more than fiat currencies? Bitcoin is decentralized and fiat currencies are centralized. Once you put your bitcoins on bank, it no longer possess the decentralized characteristics. It becomes more like a centralized currency where you will lose full control of your coins. If you want to get fixed amount of profit per year from bank just stick with traditional currencies. Bitcoin and banks will never go together.

I think due to bitcoins's decentralized nature they will never buy into the idea. This especially goes to the government banks.
