My opinion is that banks will live for a long time. Although they have an old system, but it is very well established and the guys from the banking system will not give up so simply a piece of the pie in favor of the technology of blockchain.
Yes that is true that banks will continue to survive for a long long time. I do not think that banks are going to quit so soon, because still majority of people are using banks for their main purposes. They are using bitcoin only as optional.
i think the bank is a government relationship and a financial support for a country, so i think conventional banks will still exist, and government will not leave it. even though bank system is changed to blockchain
With the support of the government, the banking system will last forever until government domination ends, the blockchain will not have the opportunity to enter, although it is new technology but the government is very disgusted with it. So you can stop the dream of bank blockchain right here, you have sank so long in the blockchain and crypto world, it always makes you think blockchain is very important to the world but you probably do not know that most people in the world do not care about it.
