I think that the RBI is going to continuously give such statements so as to avoid more increased adoption of bitcoins by the common folks of India. Most Indians don't look into the technical side of it, some don't have the capability to understand while some don't bother looking into it. The Government and RBI will be trying to regulate them, which cannot be achieved so they'll probably come with their own cryptocurrency. So if they are able to stop few investments into Bitcoins, those investments will likely be invested into the cryptocurrency the RBI / GOI comes up with. So basically block the investment into Bitcoins and fund their project. That what I think.
