Zebpay is the best Indian exchange/wallet according to me. I use Zebpay on a regular basis and find it completely soothing to handle transactions.
The deposit and withdraw are smooth enough to make the transfers and buying and selling BTC is hassle free. Although I don't like their support as they take time to handle the queries but in most cases the query is solved withing 2-4 days. Transferrinf BTC from zebpay to another zebpay wallet is totally free and doesn't take any transaction fees
