I was not aware that Bitcoin is not allowed in India. if that is the case, I believe it might be too risky.
Bitcoin is not ban in India, what is banned is running an exchange, basically govt. started banning the banks(Exchanges bank accounts) on which customers were depositing money to buy crypto using INR, you can still buy BTC fro localbitcoin (I would not advice this platform)
or you can buy from Peer to Peer that is if someone has BTC, you can pay them and they can sell your BTC to you.
You can buy Bitcoin from coinswitch.co exchange also using your credit card in India.
