any sites other than Zebpay ??
Yes you can use Coinsecure or Unocoin. But withdrawal at Coinsecure is the best. You will get instant withdrawals many times. While that is not the case with Unocoin. Also do you want to buy/sell the btc?
You can withdraw and deposit at Zebpay also instantly on any working day.Zebpay is available only on mobile devices and that is the only disadvantage of Zebpay.I hope they have a full website also or some similar app for Windows pc so that it can be accessed from both.
In india ,majority of people use phone more than desktop or laptop.i would say mostly all prefer using phone .so thats why zebpay has launched its app rather coming to desktop version.
