This is the reality as long as we are modern.  Think back to ancient times when people didn't know what money was.  They make transactions through products.  That is, one would replace the other's meat with vegetables.  And that was the process of their transaction.  People have changed over the course of the day.  At one time they used the leaves of the tree as a means of transaction.  Later, gold coins and silver coins were gradually introduced.  And today paper money has been created to make transactions easier.  But even 300 years ago there was no bank, and today we cannot go without a bank.  In the same way, 20 to 30 years from now, maybe the banking system will go up.  Because people don't want anyone else to know their bank account.  And people will choose digital cryptocurrency as an alternative to this bank.  Bitcoin may be his alternative.  Bitcoin is a decentralized process. This means that there is no need for a third party in this process.  There will come a time when people will no longer take the help of banks.  They will manage all the activities of daily life starting from shopping through digital cryptocurrency.

  If my idea proves to be correct, will the government of the country accept it?
 1. Will the government of a country ever want their banking sector to be abolished?
 2.  How will the government collect taxes from the people?
 3.  If the government can't keep track of people's legitimate money, won't corruption increase?
