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.
I guess online retailers would love to use BTC since it will cut their banking fees. Once the retailers starts using bitcoins, the awareness of cryptos will also increase throughout the country.
BUT the problem here for the retails is the uncertainty of government's position on cryptos.
