Rates depends upon demand & the day when you meet... if you looking for ZEBPAY rate, than have to add commission (Zebpay charges 1.2%) to get the exact rates. Currently the most secured considered is UNOCOIN with higher BTC volume and zero commission.  But all these rates on different exchanges are anyway different.

We dont intend to make huge profit from this deal by charging higher rates. Its just a thought so BTC can be transferred easily and there is trust factor on both parties.
