I don't think there is a definitive answer on this. The most recent language from the RBI (dated February 1, 2017) can be found here: https://rbi.org.in/scripts/bs_pressreleasedisplay.aspx?prid=39435
"The Reserve Bank of India had cautioned the users, holders and traders of Virtual Currencies (VCs), including Bitcoins, about the potential financial, operational, legal, customer protection and security related risks that they are exposing themselves to, vide its press release dated December 24, 2013.
The Reserve Bank of India advises that it has not given any licence / authorisation to any entity / company to operate such schemes or deal with Bitcoin or any virtual currency. As such, any user, holder, investor, trader, etc. dealing with Virtual Currencies will be doing so at their own risk."
