Opening up a free and virtual trading platform very similar to that of Kite where a certain amount of virtual cash is provided to the user to trade and invest would be beneficial to Zerodha in the following ways: -
Prospective clients get a chance to interact with the Kite platform and understand it better before they actually open up a trading platform with Zerodha.
It increases visibility and brand reach of Zerodha.
Though there are a lot of virtual trading platforms available, I personally have found Kite to probably be the easiest trading platform to use and thus a virtual trading platform by Zerodha would actually be successful despite the competition.
This is my opinion. What are your opinions regarding opening up of a virtual trading platform by Zerodha?
