Zebpay is the best exchange here in our country and I trust it.
Yes Zebpay is the first comapny to start btc trading in India and now CS is also expanding along with Unocoin. But in Unocoin has the highest fees of 1.15% while zebpay offers 0% fees for transaction with them.
Undoubtedly zebpay emerge as best exchange available via phone in india.its 3 step transaction is really good ,just upload your id proof and attach back and go,very convinient exchange for mobile users.
Coinsecure and unocoin are also good , coinsecure service is also very fast.
