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.
The scenario within India is different. Myself too see the emergence of more number of exchanges for cryptocurrencies. In reality majority of the exchanges were registered on foreign countries and is functional on India. The government have revealed a statement that cryptocurrency is an unregulated digital asset and not a legal tender. Government once issued ban on the usage of cryptocurrency, and now the lift is being lifted. This is called transition, and the same could happen with other countries that are against cryptocurrency usage in the past. This transition is the factor that makes the future of bitcoin more effective.
