Is it possible to withdraw regular money from the bank at any time?

The basic principle of depositing money in the bank is the freedom of withdrawal, as long as it is your saved money that can be taken out at any time.
If you keep it on a regular basis, you can also take it at any time, but if it is not taken out, it will not calculate the interest rate. It will not give you a regular interest rate, but will only give you current interest. This one will have less interest. However, there is no change in the principal amount.
