You'll have to buy it off Zebpay/Coinsecure to initially beging with or you can even try cex.io.
For trading start with Poloniex, and then go to Bittrex.
We have Koinex and Bitpay coming up for buying/selling alt coins. Check them out.
I like the platform UX for Kionex and the order books look to be just started to filling up, I bet in a year or two it will have the highest volume in India going past Zebpay and be the market leader in India for bitcoins.I hope they don't have the spread too much like zebpay /unocoin.How much time does it take the kyc to get verified on Kionex?
