There's no need to be confused and panicked to buy Ethereum because I'm sure India is also very open to creating a Binance Exchange account.
I'm sure after confirmation of the Binance account and the account is Verified then the OP will be able to buy and Withdraw Ethereum to his India-based debit card.
This experience was the same as mine when creating a Binance exchange account.
Yeah, Until now I didnt hear india goverment ban exchange.
So I think there is no problem about it.
India people can create account at exchange such binance, Kucoin, Hotbit etc. Then buy etheruem there
Lately I hear india goverment allow bitcoin and crypto currency, but take the tax from this.
So, I think OP doesnt have problem about how to buy ethereum in India again.
