Because people don't read. They just spread FUD and hear what they want to here and have no idea about legal issues. Anyway... Since when has banning things ever worked? >.<
Why would you want regulated entities to offer crypto assets anyway? The point of crypto is not to have regulation. Regulation just means someone can control it.
If Indian government legalize crypto currency then it will be a great news for it's public, yes India is the second most populated country in the world and I am sure the transactions and usage will be more aggressive than other countries and there is a big chance for a massive pump if they legalize crypto currency.
They have never banned it and never legalized it, they have denied any cryptocurrency trading directly from bank. The p2p options are always available, there is no illegal charge upon anybody holding the crypto coins, there is no different income tax law for crypto coins.
They won't be able to prove who has coins and who does not and that would be a massive waste of public resources. I doubt your average taxpayer is going to be happy with their tax money being spent that way when it could be used to upgrade and improve infrastructure.
