What are the benefits of holding shares in a demat account? Is it mandatory for all investors to open a Demat account in order to trade on the stock market?

In the event of a purchase, shares held in depository can be immediately transferred. There is no stamp duty that must be paid for securities transfers. All risks associated with physical certificates such as fake securities, bad delivery, and other issues are not required. This is not the case. It is recommended that securities be kept in demat format with all depository participants (DP) as more than 99% settlements at stock exchanges take place in the demat format.
