On June 24, the Reserve Bank of India recently clarified that its old notice prohibiting payments related to cryptocurrencies is no longer valid. People familiar with the matter said that although the National Bank of India, HDFC Bank, Axis Bank and ICICI Bank and other large banks are still reluctant to provide services, some smaller banks such as IDFC Bank have begun to provide services for some exchanges. Now, more and more small banks feel that the market is sluggish and have banned cryptocurrency accounts.
Banks may have their own terms and conditions, if their terms are breaking the laws of their central bank then you need to file a case against the banks which are violating the central bank guidelines. Anyway which is also not going to work since government will support the banks not the people and the justice is on the hands of leaders.
So change your bank and move your deposit to the banks which is accepting bitcoin and cryptocurrency trading.
