Well, we do have other options here. For instance, if I were in this situation then I would still continue using crypto as if nothing had happened.
The problem only arises on buying/selling crypto for fiat. I would stop using the Indian currency and would trade with whatever I have left.
May be at some point in future the government of India will accept cryptocurrencies, I would patiently wait until then.
If required we can also use other currencies for withdrawal such as using USD and getting the amount in paypal.
Also, peer to peer exchanges such as WazirX can be used since it is very hard for the government to judge the amount that it coming from such sources.
If we are in contact with local sellers then we can make the deal in cash too but it's quite risky this way.
