Could it be due to a general expectation for USD to collapse in the near future. Should a devaluation occur, it would be rather awkward for anyone with a significant bitusd position.
Probably more sensible to hold bitgold, bitsilver and their ilk....
I doubt this is the reason...I for once want some bitusd but I do not plan to buy them at 10% above the peg and I don't want some bitusd if the market cap of Bitshares is at these levels..
Why Bitbtc has no trading as well??
I think the reason that the bitusd book is like that compared to the bitcny book is because most of the trading happens in btc38 between btc and cny and bts.. usd trading is just non existent..BTS is still alive because of Chinese investors mostly I think, who see the potential more clearly than the rest..
Unless there are actually markets that accept at all times bitusd=usd at all times with high volume
I think that book will look like this forever..
I may be wrong though..
