I think no exchanges were closed actually.
an Indian agency is trying to freeze a Bitcoin exchange.
The key word here is " trying" so no worries. This is just the way journalists like to present their news, to attract more attention.
I dint say anyone has been closed. I asked which one they are trying to close? I think there are ~4 exchanges in India and all operators are on this forum. So, the operator might tell us which one is under scrutiny by Narcotics Control Bureau. If any one is under scrutiny, operator must have been intimidated by now.
I found ZebPay was aggressively promoting this video. So, may be NCB is investigating ZebPay. But, whether it is ZebPay or any other exchange, I dont see why they should be shut down because of this. If criminals keep money in bank, do they shut down banks itself?
