E Commerce industry is on a boom right now and it will certainly grow. The reason being it is only a few of Indians living in metros and medium cities who have used e commerce but still there is a large population who have not touched it.
As many e commerce players are going app only that means the power of
e-commerce will come to the mobile owner and mobile is reaching slowly into our far flung areas.
So as the reach increases and logistics will support more and more people will go to e commerce and the boom will continue.
There will be certainly a settling phase where the graph may go down but soon it will rise again and more and more people will join the ecommerce revolution.
Another point is more and more people are starting to sell online in India. that number is still too less what it really should be. So as these people grow, awareness will grow and sales will grow.
I hope logistics, payment systems and infrastructure in India evolves at the same rate to support this revolution.
