The only website we have right now that looks trustable is buysellbitco.in and downside is they work 8AM to 10PM and pause the trading at any time of day whenever they feel like.
When are we going to see a 24hr exchange here in India that doesn't have any daily limits?
Please try
INRBTC, we have trades which have been executed on all odd times , even now the bitcoins are being traded.
It is 24 Hrs open, it has no limits
and when more of you start using it , it will have a much higher depth too.
