It is foolish to expect that the traditional banking system will disappear with the advent and development of cryptocurrency. Banks perform a much broader function than cryptocurrency, and therefore cryptocurrency simply cannot replace the banking system. For example, banks serve the financial and economic activities of business entities. At the same time, the necessary information is recorded for tax and audit purposes, such as the justification for the transfer of monetary amounts, indicating the contract number and other necessary information. Cryptocurrency, by its nature, cannot do this.
