I really don't know what the Indian government is thinking for banning the crypto trading again. There's a rumor circulating around that the Indian government might want to make their own crypto currency so that they can control the people who are trading. This should be a centralized exchange where they only allowed their own crypto currency to be use by the people but I highly doubt it if people would follow their government project.
These are just unsubstantiated rumors. Check my previous post in this thread. No bill related to cryptocurrency is scheduled for discussion during this year's parliament session. Every now and then, some people want to spread FUD and will make rumors such as this one. If they are to be believed, India has banned Bitcoin dozens of times already. Don't fall in to this trap, and I am sure that India is not going to ban BTC for another 4-5 years.
