Hi Sanjay Nehru, Yes, This is what most of the traders are following in the market. For every side, there are a few cons that you need to consider before starting option selling.

1) Higher Margin - The margin requirement is very high for option selling you can check the margin requirement using Fyers margin calculator.
2) Unlimited Risk- When you buy options, your risk is restricted to the premium paid. However, selling options exposes you to potentially unlimited risk. For instance, selling naked calls can result in substantial losses if the underlying asset experiences a significant rally.
3) The market trend - Option selling is most successful in neutral to mildly bullish or bearish market conditions, yet it can incur significant losses if the market strongly moves against your position.
4) Physical delivery -This means you become obligated to either buy or sell the underlying asset. (Only applicable to the Stock options)

Hope this will help you to understand the risk involved. Also, you can read more about the option strategy to reduce the risk and plan your trading. https://fyers.in/school-of-stocks/module/options-strategies.html
