Yes it is absolutely back here is another blog post citing the same thing:
https://news.bitcoin.com/zebpay-relaunch-india/ . Looks like they are inspired by the WazirX's Acquisition by Binance. Moreover the primary reason why they left was RBI banning banking transactions with crypto exchanges but then WAZIRX realized that how nicely can P2P work in such an environment. Looks like ZEBPAY will now focus on becoming a full fledged exchange with P2P facility in India.
I doubt the correctness of this news. Because the website is showing "500 server error". I don't know is it only me or everyone else is getting the same error!
Zebpay.com works fine for me. Moreover, many existing Zebpay users including me got emails that they are due for a comeback. So I guess the news is legit.
Wallet maintenance fee? Looks something new for me.
Back in 2018, when they closed, they had informed that they would charge fee for the safekeeping of the Crypto which was not withdrawn by the users after the withdrawal deadline. I guess that's what they are calling as Wallet Maintenance fee. Dont know the earlier charges were, but this was discussed in the latest email as well
Therefore, please take notice that from March 1st, 2020, we will charge a monthly fee of 0.0001 BTC per member, equal (on average) to roughly USD 0.80 / SGD 1.1 / INR 60
The line
"passive Income and Borrowing program" clearly shows that they are ready to become the first exchange to dive into margin trading with leverage in India. They might even launch some investment schemes just like Binance has been doing lately. But I don't think there is much of an Indian market which would want to trade on an Indian exchange now. Everyone is pretty comfortable with exchanges like Binance and Huobi etc.
