Hey @rahulbasu

I've recently joined it and I am skeptical. Your review is helpful. I can relate to your points like,

It doesn't have Google Two Factor Authenctication
It doesn't have App
It is not popular yet.

But,
It's one of the few cryptocurrency exchange in India.
We have many cryptocurrency options.
The fees is low compared to other Bitcoin exchanges like Zebpay and Unocoin.

I think it's new site but it will grow rapidly.
