1= the first thing is layout and design of the zebpay is not such user friendly as compare to other.
2= the second thing is zebpay is just a third party platform for bit coin sailing and buying so you have to pay fix charges even the rate are fluctuate in other direct bitcoin trading web/wallet but zebpay remains its price same and higher so I think when we have direct trading option then why to go for zebpay.
3= the third thing how can it would be useful when we are paying extra amount for sale and resale. I have got other for trading directly into bitcoin and sale government and IT department can strict on this wallet.
