Right now only Koinex is offering Ethereum to buy in rupees. It is one of the 5 coins offered by Koinex to buy in INR (Indian National Rupees).
Process is very simple:
- Log in with email and mobile no.
- You need to create profile with PAN card, Aadhar card and fill KYC details followed by instructions.
- After verification, you will get a unique account no to add in Internet banking.
Verification takes 24 hours generally. If any technical development is going on then it may take some more time.
You can transfer amount in the particular account and purchase Ether and other 5 cryptocoins on Koinex.
Next could be Bitxoxo as they have listed Ether as upcoming. Bitbay was also in league which was offering buying and trading in rupees but still not operational.
