As you have seen that more and more users from India are now getting into crypto currency and companies like zebpay and coinsecure makes it easier to buy bitcoins.
So do you think merchants like flipkart and amazon should use bitcoin as alternate payment gateway.
For country like India accepting and using in in day to day transactions bitcoin will be a big change. I think flipkart, snapdeal etc. will slowly introduce bitcoin as alternate payment method. Right now we can buy vouchers from them and they are on right track.
