Hi Hive account@firepower,
I have only one account on unocoin and I found the exchange is good one. However I haven't used any other exchanges till now. So I can't make any comparison, but sometimes I have seen huge difference between buying and selling price on unocoin. Yesterday I got a email from unocoin regarding RBI notice

Our stance regarding the recent
RBI notice
Dear Unocoin Users,
We have always believed in offering our customers with the best and most secure blockchain services. Since December 2013, our team has been serving the Indian bitcoin and blockchain community by continuously innovating:

Industry leading Crypto-Assets and Blockchain company offering two market leading platforms: Unocoin, an online brokerage for trading bitcoin, and Unodax, an order matching crypto exchange.
Providing 24x7 customer support by email and telephone.
Unique buying plans such as SBP (systematic buying plans) & OTC (over the counter) along with multi-tier membership programs.
Introducing new features such as Crypto Basket, etc.

Due to the RBI’s recent notification on 'Prohibition on Dealing in Virtual Currencies', our banking relationships are likely to be disrupted on or before July 5th, 2018. We are in the process of deploying new mechanisms for INR deposits and withdrawals. This is not a small undertaking and it will take us some time to deploy new solutions, please do not panic. Until further notice from our team, customers may continue INR deposits and withdrawals from Unocoin through normal banking channels as long as our bank accounts are functional beyond which the bank accounts based deposits and withdrawals of INR won’t be available till the RBI’s notice stay effective.
Please feel free to contact us at support@unocoin.com in case of queries.
Regards,
Unocoin Team
