I am not surprised, Scam exchanges like p2pb2b do a lot of washing trading and report fake volumes.
Just try and checkout Digifinex's daily volume  It all faked.

I once tried to trade on that platform, placed my sell order just around the sell price at that time but it never went through after almost 4 days. The trading history showed that the bidding price had even gone way above my sell order but still, it was never touched 

I got so pissed, withdrew all my holdings and promised never to every used it again.
