In India cryptocurrency is not legal as well as not illegal. There is no any official permission for use of Bitcoin or any other coin but still many crypto exchanges are running currently in India also getting advertisements on TV, YouTube & many more places. Here government also believe there is future of cryptocurrency. As we know bitcoin started trading from around 0.0008$ to 0.08$ and now it's approx 50,000 $$. But there is also risk side of getting loss for those who don't have some knowledge of trading and those who don't have patience. Keeping in view of these all things government is talking time for making it fully legal. We believe a very good future of Bitcoin & many of the Indian started doing trading in cryptocurrency.
Also as long as the internet is live in this world then many more users, organization, industries, etc will involve and enter to the crypto bitcoin market. I personally believe Bitcoin will reach a greater heights in the future and a real holder can understand this.
I am not Indian nor living in India but I think India is quite neutral to this, technically, rolling out crypto advertisements is already a form of legality, so technically speaking, Bitcoin is indeed legal there, CoinSwitch operates as a digital exchange used by a lot of Indian citizens, if digital exchanges there can operate freely, then the government is indeed allowing crypto activities but never supports them.
Technology continues to advance, and so does our innovation to the environment, right now, technology continues to surge through several advancements, and so does cryptocurrency along with Bitcoin, technology will never go back and only goes forward, so does with our internet, so I doubt the internet will disappear unless the country's government decides to ban the access to internet.
