A Demat account is an account that holds share certificates and other investment instruments like ETFs or mutual funds in electronic form. Therefore, if you own a Demat account then you don’t have to maintain any physical records or certificates of various securities.

You will have to open this account if you are interested in investing in shares, mutual funds, bonds, and other financial assets.
Here are some of the main benefits of creating an online Demat account:
Eliminates the risk of misuse of certificates
Holding physical certificates of shares, bonds, equities, and other securities is a challenging task as these certificates tend to get misplaced, torn, or damaged.
Saves time & money
Also, postage duty, commutation expenses, and other charges get minimized and your time is also saved as the transfer of securities can be done online.
Trade anytime from anywhere
Since a Demat account can be handled via a mobile, laptop, or tablet, you can trade anytime from your home, office, or from anywhere.
Monitoring assets becomes easy
Corporate Actions related to shares get updated in the Demat Account
If you hold shares of a company that declares bonus shares, stock splits, dividends, they automatically get updated in the Demat Account.
There is no single best Demat account in India as it depends on your financial goals and requirements. If you are a beginner or do not invest regularly then you can open a BSDA (Basic Service Demat Account) that charges a minimal AMC (Account Management Charges) from the account holder.
Also, you will need the help of a depository participant i.e. DP that offers a partial or entire suite of brokerage services. Keep in mind that the DP has to be authorized by either NSDL or CDSL which are the depository organizations in India.
Full-service brokerage firms offer many products and provide advisory by experts and customer support services. On the other hand, discount brokers offer limited products and few services that might prove handy to beginners or those individuals who require limited assistance.
A better choice would be to go for the brokers who provide numerous services and products at a competitive price range. For instance, some discount brokers allow you to avail different types of investments and provides a platform to trade equipped with the latest technologies.
Moreover, these services and benefits can be accessed via affordable subscription packages. Therefore, it proves to be one of the better options if you want to create Demat account online with multiple products and services to choose from.
